Materials which can provide strawberry, rosy, banana, woody, piney, minty, fruity and jasmine aromas with floral, fruity, spicy, green, hawthorne, ozoney and anisic topnotes are highly desirable in the art of perfumery. Many of the natural substances which provide such fragrance nuances and contribute the desired nuances to perfumery compositions are high in cost, vary in quality from one batch to another and/or are generally subject to the usual variations of natural products.

The prior art contains a large number of teachings regarding the use of organic carbonates in augmenting or enhancing the aroma of perfumes. Thus, U.S. Pat. No. 4,033,993 discloses the use of organic carbonates defined according to the structure: ##STR25## wherein R.sub.1 is a moiety having from 8 to 12 carbon atoms selected from the group consisting of alkylcyclohexyl, alkenylcyclohexyl, alkynylcyclohexyl and cycloalkyl and R.sub.2 is a moiety selected from the group consisting of alkyl having from 1 to 5 carbon atoms, alkenyl having from 2 to 5 carbon atoms and alkynyl having from 2 to 5 carbon atoms. U.S. Pat. No. 4,033,993 describes, for example, methyl-1-ethynycyclohexyl carbonate having a fruity, herbal complex odor and distinct fragrance of dill. In addition, U.S. Pat. No. 4,033,993 describes methyl cyclooctyl carbonate as having a herbal, natural and complex fragrance which is distinguished by a strong and long clinging flowery jasmine scent and further indicates its use in jasmine perfume compositions. U.S. Pat. No. 4,033,993 describes the preparation of the compounds defined according to the structure: ##STR26## according to the reaction: ##STR27## wherein R.sub.1 and R.sub.2 are defined as above.

In addition, U.S. Pat.

Described in U.S. Pat. No. 4,080,309 are also such compounds as methyl cyclooctyl carbonate and the use thereof in jasmine perfume formulations. As is the case in U.S. Pat. No. 4,033,993, the carbonates of U.S. Pat. No. 4,080,309 are indicated to be prepared according to the reaction: ##STR29##

4-Cyclooctenyl alkyl carbonates defined according to the structure: ##STR30## wherein R.sub.4 is methyl or ethyl and reaction products including a major proportion of said 4-cyclooctenyl alkyl carbonates and a minor proportion of bicyclooctanyl carbonates having the structure: ##STR31## wherein R.sub.5 is methyl or ethyl and uses thereof in augmenting or enhancing the aroma of perfume compositions, colognes and perfumed articles are described in U.S. Pat. No. 4,452,730 issued on June 5, 1984.

Referring to the drawings in FIGS. 15 and 16, the invention embodied therein comprises a device for forming scented polymer pellets (e.g., polyethylene, polypropylene or mixtures such as polyepsiloncaprolactone and polyethylene or polypropylene or copolymers of polyvinyl acetate and polyethylene or the like) which comprises a vat or container 210 into which a polymer or mixture of polymers admixed with one of the oxobicyclononane derivatives of our invention is placed.

The container is closed by an air-tight lid 228 clamped to the container by clamps 265. A stirrer 273 traverses the lid or cover 228 in air-tight manner and is rotated in a suitable manner. The surrounding cylinder 212 having heating coils which are supplied with electrical current through cable 214 from a rheostat or control 216 is operated to maintain the temperature inside the container 210 such that the polymer such as polyethylene in the container will be maintained at a molten or liquid state. It has been found advantageous to employ a colorless, odorless polymer such as low density polyethylene with a viscosity ranging between about 180 and about 220 centistokes and having a melting point in the neighborhood of 220.degree. F. The heater 212 is operated to maintain the upper portion of the container 210 within the temperature range of from 250.degree.-350.degree. F. An additional bottom heater 218 is regulated through a control 220 connected thereto through a connecting wire 222 to maintain the lower portion of the container 210 within the temperature range of from 250.degree.-350.degree. F.

In accordance with this aspect of the invention, a polymer such as polyethylene or polypropylene is added to the container 210 and is then heated from 10 to 12 hours whereafter an aroma imparting material containing at least one of the oxobicyclononane derivatives of our invention or at least one of the oxobicyclononane derivatives of our invention per se is quickly added to the melt. The mixture containing the oxobicyclononane derivative of our invention must be compatible with the polymer and forms a homogeneous liquid melt therewith. The heat resisting mixture generally containing from 10 to 40% by weight of the mixture of at least one of the oxobicyclononane derivatives of our invention or a mixture thereof is added to container 210; the mixture is stirred for a few minutes, for example, 5-15 minutes, and maintained within the temperature range as indicated previously by the heating coils 212 and 218 respectively. The controls 216 and 220 are connected through cables 224 and 226 through a suitable supply of electric current for supplying the power for heating purposes.

Thereafter, the valve "V" is opened permitting the mass to flow outwardly through a conduit 232 having a multiplicity of orifices 234 adjacent the lower side thereof. The outer end of the conduit 232 is closed so that the liquid polymer and at least one of the oxobicyclononane derivatives of our invention or mixture containing same will continuously drop or drip through the orifices 234 downwardly from the conduit 232. During this time, the temperature of the polymer and the perfumant mixture containing at least one of the oxobicyclononane derivatives of our invention in the container 210 is accurately controlled so that a temperature in the range of from 210.degree. up to 275.degree. F. will be maintained in the material exiting in the conduit 232. The regulation of the temperature through the control 216 and the control 220 is essential in order to insure temperature balance to provide for the continuous dropping or dripping of the molten polymer and the perfumant containing at least one of the oxobicyclononane derivatives of our invention through the orifices 234 at a range which will insure the formation of droplets 236 which will fall downwardly onto a moving conveyor belt 238 trained to run between conveyor wheels 240 and 242 beneath the conduit 232. When the droplets 236 fall onto the conveyor belt 238 they form pellets 244 which harden almost instantaneously and fall off the end of the conveyor 238 into a container 246 which is advantageously filled with water or some other suitable liquid to insure the rapid cooling of each of the pellets. The pellets are then collected from the container 246 and packaged for shipment.

A feature of the invention is the provision for the moistening of the conveyor belt 238 to insure the rapid formation of the solid polymer-aromatizing agent containing pellets 244 without sticking to the belt. The belt 238 is advantageously of a material which will not normally stick to a melted polymer, but the moistening means 248 insures a sufficiently cold temperature of the belt surface for the adequate formation of the pellets 244. The moistening means comprises a container 250 which is continuously fed with water 252 to maintain a level 254 for moistening a sponge element 256 which bears against the exterior surface of the belt 238.

The present invention also provides an economically efficient process for synthesizing the compounds defined according to the structure: ##STR119## by first reacting bicyclononadiene having the structure: ##STR120## with formic acid according to the reaction: ##STR121## and then reacting the resulting formate compound with the carbonate having the structure: ##STR122## (wherein R represents methyl or ethyl) according to the reaction: ##STR123##

The bicyclononene formate is formed from bicyclononadiene by reaction of bicyclononadiene with formic acid. The reaction is carried out at reflux conditions for a period sufficient to yield a product containing greater than 80% bicyclononene formate. The mole ratio of formic acid:bicyclononadiene may vary between about 2:1 up to about 7:1 with a preferred mole ratio of between 5.5:1 and 6:1 of formic acid:bicyclononadiene. At the end of the reaction the reaction product, the bicyclononene formate is distilled. The crude reaction product contains the compounds having the structures: ##STR124## with the majority of the mixture being the compounds having the structures: ##STR125## The compound having the structure: ##STR126## is separated out from the reaction mass by fractional distillation leaving the compounds having the structures: ##STR127## These compounds may be separated from one another whereby the group of compounds having the structures: ##STR128## may be separated from the group of compounds having the structures: ##STR129## by preparative liquid chromatography. However, from a practical standpoint the fractional distillation product is sufficient for the purposes of use of the resulting bicyclononenyl formates as intermediates in preparing carbonates which are subsequently useful in perfumery.

The resulting mixture of compounds having the structures: ##STR130## is then reacted with either diethyl carbonate or dimethyl carbonate defined according to the structure: ##STR131## wherein R represents methyl or ethyl in the presence of an alkali metal alkoxide catalyst such as sodium methoxide, sodium ethoxide, sodium isopropoxide, potassium t-butoxide as well as other metal alkoxides such as aluminum isopropoxide. The reaction temperature may vary between 50.degree. C. and 90.degree. C. with a preferred reaction temperature of between 60.degree. and 80.degree. C.

The mole ratio of dialkyl carbonate to bicyclononenyl formate may vary from about 2:1 up to about 4:1 with a preferred mole ratio of about 2.8:1. The concentration of alkali metal alkoxide or other metal alkoxide in the reaction mass may vary from about 0.03 moles per liter up to about 0.5 moles per liter with a preferred concentration of alkali metal alkoxide or other metal alkoxide in the reaction mass being about 0.05 moles per liter. At the end of the reaction the reaction mass is quenched with weak acid such as acetic acid. The reaction mass is then fractionally distilled thereby recovering a mixture of carbonates having the structures: ##STR132## with the major (e.g., greater than 75%) portion of carbonates having the structures: ##STR133## The group of carbonates having the structures: ##STR134## may be separated by preparative liquid chromatograph from the group of carbonates having the structures: ##STR135## However from a practical standpoint it is preferable not to so separate the fractional distillation products but to use such fractional distillation products "as is" for their organoleptic properties in perfumery, e.g., augmenting or enhancing the aroma of perfume compositions, perfumed articles and colognes.

The bicyclononenyl formates defined according to the structure: ##STR136## usually mixtures of bicyclononenyl formates having the structure: ##STR137## may also be utilized to prepare other compositions of matter of our invention, particularly the compounds having the structures: ##STR138##

In those cases where the compounds having the structures: ##STR139## are to be prepared, these materials are prepared using as a starting material the compounds having the structure: ##STR140## which, in turn, is prepared by hydrolyzing the compounds having the structure: ##STR141##

The hydrolysis reaction on the compound or compounds having the structure: ##STR142## is as follows: ##STR143## The reaction is carried out in a strong base such as sodium hydroxide or potassium hydroxide with a mole ratio of hydroxyl ion:formate being between about 2:1 and about 1:1 with a preferred mole ratio of hydroxyl ion:formate being about 1.5:1. The reaction temperature may vary between about 40.degree. and 60.degree. C. with a preferred reaction temperature of about 50.degree. C. At the end of the reaction, the reaction mass is neutralized and the resulting product is preferably fractionally distilled from the reaction mass. The resulting compounds may be used "as is", or they may be separated by means of column chromatography or they may be further reacted as shown, infra.

Compounds having the structure: ##STR144## may be prepared according to the reaction: ##STR145## whereby the compounds having the structure: ##STR146## are reacted with an excess of oxidizing agent such as potassium dichromate in sulfuric acid, in the presence of an inert solvent such as isopropyl alcohol. The mole ratio of compound having the structure: ##STR147## to dichromate oxidizing agent may vary from about 1:1 up to about 1:1.5 with, preferably, a slight excess of dichromate ion being present. The reaction is carried out at a temperature of between about 30.degree. and about 40.degree. C. At the end of the reaction, the reaction mass is extracted with a solvent such a toluene and the organic extracts are neutralized using aqueous base. The reaction mass is then fractionally distilled to yield the compounds having the structure: ##STR148## which may be used "as is" or separated prior to use by means of column chromatography.

Furthermore, the compounds having the structure: ##STR149## may be esterified as with acetic anhydride or propionic anhydride to form the corresponding acetic acid esters or propionic acid esters according to the reactions: ##STR150##

The reaction is carried out using a slight molar excess of alkanoic anhydride, e.g., acetic anhydride or propionic anhydride, e.g., about a 15% excess. The reaction is carried out at a temperature in the range of from about 115.degree. C. up to about 140.degree. C. At the end of the reaction, the reaction mass is quenched with water and the organic phase is separated and neutralized with weak base such as sodium bicarbonate. The reaction mass is then fractionally distilled yielding the compounds having the structures: ##STR151## (in the case of using an acetic anhydride starting material) and ##STR152## (in the case of using a propionic acid anhydride starting material).

The resulting mixtures can be used "as is" or they can be separated into their component isomers as by means of column chromatography.

As stated, supra, the oxobicyclononane derivatives of our invention can be used to contribute strawberry, rosey, banana, woody, piney, minty, fruity and jasmine aromas with floral, fruity, spicy, green, hawthorne, ozoney and anisic topnotes to perfume compositions, perfumed articles and colognes with the perfumed articles being such materials as solid or liquid anionic, cationic, nonionic or zwitterionic detergents, perfumed polymers, fabric softener compositions, fabric softener articles, optical brighteners, fabric conditions, hair preparations, shampoos and hair sprays. As olfactory agents the oxobicyclononane derivatives of our invention can be formulated into or used as components of a "perfume composition".

The term "perfume composition" is used herein to mean a mixture of organic compounds including, for example, alcohols other than the alcohols of our invention, aldehydes, ketones other than the ketones of our invention, nitriles, ethers, lactones, esters other than the carbonates and alkanoic acid esters of our invention and, frequently, hydrocarbons which are admixed so that the combined odors of the individual components produce a pleasant or desired fragrance. Such perfume compositions usually contain: (a) the main note or the "bouquet" or foundation stone of the composition; (b) modifiers which round off and accompany the main note; (c) fixatives which include odorous substances which lend a particular note to the perfume throughout all stages of evaporation and substances which retard evaporation; and (d) top notes which are usually low-boiling, fresh-smelling materials.

In perfume compositions, the individual component will contribute its particular olfactory characteristics, but the overall effect of the perfume composition will be the sum of each of the effects of each of the ingredients. Thus, the individual compounds of this invention or mixtures thereof can be used to alter the aroma characteristics of the perfume composition, for example, by highlighting or moderating the olfactory reaction contributed by another ingredient in the composition.

The amount of oxobicyclononane derivative(s) of our invention which will be effective in perfume compositions depends upon many factors including the other ingredients, their amounts and the effects which are desired. It has been found that perfume compositions containing as little as 0.1% of the oxobicyclononane derivative(s) of our invention or even less and perfume compositions containing as much as 70% of one or more of the oxobicyclononane derivative(s) of our invention can be used to impart interesting, strawberry, rosey, banana, woody, piney, minty, fruity and jasmine aromas with floral, fruity, spicy, green, hawthorne, ozoney and anisic topnotes to perfumed articles, perfume compositions and colognes. Such perfumed articles include fabric softener compositions, drier-added fabric softener articles, cosmetic powders, talcs, solid or liquid anionic, cationic, nonionic or zwitterionic detergents and perfumed polymers. The amount employed can range up to 70% as stated, supra, and will depend on considerations of cost, nature and of the end product and the effect desired on the finished product and particular fragrance sought.

Thus, one or more of the oxobicyclononane derivative(s) of our invention can be used alone or in a perfume composition as an olfactory component, in solid or liquid anionic, cationic, nonionic or zwitterionic detergents (including hand soaps) perfumed polymers (those which are microporous and those which are macroporous and contain particulate absorbent fillers such as talc), space odorants and deodorants; perfumes, colognes, toilet waters, bath salts, hair preparations such as lacquers, brilliantines, pomades and shampoos; cosmetic preparations such as creams, deodorants, hand lotions and sun screens; powders such as talcs, dusting powders, face powders and the like.

When used as an olfactory component of a perfumed article such as a microporous polymer or a macroporous polymer containing an absorbent filler or such as a solid or liquid cationic, anionic, nonionic or zwitterionic detergent or of a cosmetic powder, as little as 0.01% of one or more of the oxobicyclononane derivative(s) of our invention will suffice to provide an interesting strawberry, rosey, banana, woody, piney, minty, fruity and jasmine aromas with floral, fruity, spicy, green, hawthorne, ozoney and anisic topnotes. Generally, no more than 0.8% of one or more of the oxobicyclononane derivative(s) of our invention is required. Thus, the range of oxobicyclononane derivative(s) in perfumed articles may vary from about 0.01% up to about 0.8%.

In addition, the perfume compositions of our invention can contain a vehicle or carrier for the oxobicyclononane derivative(s) of our invention alone or with other ingredients. The vehicle can be a liquid such as an alcohol such as ethanol, a glycol such as propylene glycol or the like. The carrier can be an absorbent solid such as a gum (e.g., xanthan gum or gum arabic) or components for encapsulating the composition as by coacervation using gelatin or by forming a polymeric shell around a liquid perfume center by means of the use of a urea formaldehyde prepolymer.

The following Examples I, II, XIII, XIV, XV, XVI and XVII set forth processes for preparing the oxobicyclononane derivatives of our invention. Examples III-XII and the examples following Example XVII set forth methods for using the oxobicyclononane derivatives of our invention for their organoleptic properties.
