This invention relates to polyalkyl indanyl n-propyl and allyl ethers having the generic structure: ##STR2## wherein the dashed line represents a carbon-carbon single bond or a carbon-carbon double bond; wherein R.sub.3 represents methyl or hydrogen; wherein R.sub.1, R.sub.2, R.sub.4 and R.sub.5 each represents methyl or ethyl with the provisos that:

1. at least three of R.sub.1, R.sub.2, R.sub.4 and R.sub.5 is methyl;

2. when each of R.sub.1, R.sub.2, R.sub.4 and R.sub.5 is methyl, then R.sub.3 is methyl; and

3. when the dashed line is a carbon-carbon double bond then R.sub.1, R.sub.2, R.sub.3, R.sub.4 and R.sub.5 are each methyl

and uses thereof in augmenting or enhancing the aroma of perfume compositions, colognes and perfumed articles.

Materials which can provide musky, cigar box-like, amber, woody, patchouli and camphoraceous aromas with woody, winey and balsamic 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 teaching regarding the use of tetrahydro pentylmethyl indane derivatives defined according to the structure: ##STR3## wherein R represents alkyl, acyl or hydrogen in perfumery. Thus, U.S. Pat. No. 3,636,165 issued on January 18, 1972 discloses the use of the genus having the structure: in perfumery and the species of that genus having the structure: ##STR4## Such ethers are indicated to have "woody, balsamic" odors. The specification of U.S. Pat. No. 3,636,165 is incorporated herein by reference.

The compounds having the structures: ##STR5## were prepared and compared with the compounds having the structures: ##STR6## and the compounds having the structures: ##STR7## have unexpected, unobvious and advantageous properties when compared with other members of the genus which are ethers, defined according to the structure: ##STR8##

Thus, for example, the compound having the structure: ##STR9## has a "weak woody" aroma profile. Its intensity on a scale of 1 to 10 is "1" as compared to an intensity of "10" for each of the compounds having the structures: ##STR10## By the same token the compound having the structure: ##STR11## has a weak woody, balsamic aroma and its intensity on a scale of 1 to 10 can be classified as "2.1".

FIG. 6 is a section taken on line 6--6 of FIG. 5.

FIG. 1 is the GLC profile for bulked distillation fractions 20-31 of the distillation product of the reaction product of Example I containing the compounds having the structures: ##STR16## The peak indicated by reference numeral 10 is the peak for the mixture of the compounds having the structures: ##STR17## The peak indicated by reference numeral 12 is for the compound having the structure: ##STR18## (Conditions: Carbowax column programmed at 160.degree. C. isothermal).

Referring to the drawings in FIGS. 5 and 6, 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 polyalkyl indanyl n-propyl and allyl ethers 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 polyalkyl indanyl n-propyl and allyl ethers of our invention or at least one of the polyalkyl indanyl n-propyl and allyl ethers of our invention per se is quickly added to the melt. The mixture containing one of the polyalkyl indanyl n-propyl and allyl ethers 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 one of the polyalkyl indanyl n-propyl and allyl ethers 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 polyalkyl indanyl n-propyl and allyl ethers 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 polyalkyl indanyl n-propyl and allyl ethers of our invention in the container 210 is accurately controlled so that a temperature in the range of from 210.degree. F. 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 polyalkyl indanyl n-propyl and allyl ethers 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 provides polyalkyl indanyl n-propyl and allyl ethers defined according to the generic structure: ##STR19## wherein the dashed line represents a carbon-carbon single bond or a carbon-carbon double bond; wherein R.sub.3 is methyl or ethyl; and wherein R.sub.1, R.sub.2, R.sub.4 and R.sub.5 each represents the same or different methyl or ethyl with the provisos that:

(i) at least three of R.sub.1, R.sub.2, R.sub.4 and R.sub.5 is methyl;

(ii) when each of R.sub.1, R.sub.2, R.sub.4 and R.sub.5 is methyl, then R.sub.3 is methyl; and

(iii) when the dashed line is a carbon-carbon double bond then R.sub.1, R.sub.2, R.sub.3, R.sub.4 and R.sub.5 are each methyl.

The polyalkyl indanyl n-propyl and allyl ethers of our invention have utilities in perfumery; that is, in augmenting or enhancing the aroma of perfume compositions, colognes and perfumed articles including but not limited to solid or liquid anionic, cationic, nonionic or zwitterionic detergents, fabric softener compositions, fabric softener articles, cosmetic powders and hair preparations and perfumed polymers. The polyalkyl indanyl n-propyl and allyl ethers of our invention are prepared by first reacting a cyclic hexenol derivative defined according to the structure: ##STR20## with an alkali metal hydride having the formula:

according to the reaction: ##STR21## thereby forming the compounds defined according to the structure: ##STR22##

The compound having the structure: ##STR23## which is intended to include mixtures of compounds having the structures: ##STR24## is then reacted with allyl bromide or n-propyl bromide defined according to the generic structure: ##STR25## wherein the dashed line is a carbon-carbon single bond or a carbon-carbon double bond according to the reaction: ##STR26## thereby forming a member of the genus having the structure: ##STR27##

The compounds defined according to the generic structure: ##STR28## may be prepared according to the techniques as set forth in U.S. Letters Pat. No. 3,636,165 the specification of which is incorporated herein by reference.

The reactions for production of the polyalkyl indanyl n-propyl and allyl ethers of our invention defined according to the structure: ##STR29## namely, the reactions: ##STR30## may be carried out in accordance with conditions as set forth in said U.S. Letters Pat. No. 3,636,165 issued on January 18, 1972.

Conditions for such a reaction sequence are also set forth in U.S. Letters Pat. No. 4,782,192 the specification for which is incorporated herein by reference.

Thus, compounds having the generic structure: ##STR31## are first reacted with an alkali metal hydride such as sodium or potassium hydride or in the alternative with n-butyl lithium to form the resulting metal salt defined according to the generic structure:

The reaction is preferably carried out in an inert solvent such as diethyl ether or tetrahydrofuran in admixture with toluene at reflux temperatures, e.g., the boiling point of the solvent composition at atmospheric pressure.

At the end of the reaction to form the salt defined according to the generic structure: ##STR32## the said salt is then reacted with an allyl halide or a propyl halide defined according to the generic structure: ##STR33## that is, one of the compounds having the structures: ##STR34##

The reaction, to wit: ##STR35## is also carried out at reflux conditions in the presence of the solvent that was previously used in the reaction to form the salt having the structure: ##STR36##

Immediately upon the cessation of the reaction and after the solvent is stripped, the reaction mass is washed in order to purify it by means of ordinary "work up" techniques; and then the reaction mass is distilled to yield the odor acceptable fraction or fractions for use for their respective organoleptic properties.

Examples of the polyalkyl indanyl n-propyl and allyl ethers of our invention produced according to the processes of our invention and their organoleptic properties are set forth in the following Table I:

One or more of the polyalkyl indanyl n-propyl and allyl ethers of our invention and one or more auxiliary perfume ingredients including, alcohols, aldehydes, ketones, ethers other than the polyalkyl indanyl n-propyl and allyl ethers of our invention, esters, terpenic hydrocarbons, nitriles, lactones, natural essential oils and synthetic essential oils, may be admixed so that the combined odors of the individual components produce a pleasant and desired fragrance, particularly in the musk, amber and patchouli fragrances.

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) topnotes which are usually low-boiling, fresh smelling materials.

In perfume compositions, it is the individual components which contribute to their particular olfactory characteristics, however the over-all sensory effect of the perfume composition will be at least the sum total of the effects of each of the ingredients. Thus, one or more of the polyalkyl indanyl n-propyl and allyl ethers of our invention can be used to alter, modify or enhance the aroma characteristics of a perfume composition, for example, by utilizing or moderating the olfactory reaction contributed by another ingredient in the composition.

The amount of one or more of the polyalkyl indanyl n-propyl and allyl ethers of our invention which will be effective in perfume compositions as well as in perfumed articles and colognes depends on many factors, including the other ingredients, their amounts and the effects which are desired. It has been found that perfume compositions containing as little 0.01% of one or more of polyalkyl indanyl n-propyl and allyl ethers of our invention or even less (e.g., 0.005%) can be used to augment or enhance or impart musky, cigar box-like, amber, woody, patchouli and camphoraceous aromas with woody, winey and balsamic topnotes to soaps, cos- metics, solid or liquid anionic, cationic, nonionic or zwitterionic detergents, powders, fabric softeners, drier added fabric softener articles, hair conditioners and colognes. The amount employed can range up to 70% of the fragrance components and will depend upon considerations of cost, nature of the end product, the effect desired on the finished product and the particular fragrance sought.

The polyalkyl indanyl n-propyl and allyl ethers of our invention are useful (taken alone or taken further together with other ingredients in perfume compositions) as (an) olfactory component(s) in detergents and soaps, space odorants and deodorants, perfumes, colognes, toilet water, bath 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(s) as little as 1% of the polyalkyl indanyl n-propyl and allyl ethers of our invention will suffice to impart intense and long-lasting musky, cigar box-like, amber, woody, patchouli and camphoraceous aromas with woody, winey nd balsamic topnotes to various formulations such as patchouli formulations. Although generally, no more than 60% of the polyalkyl indanyl n-propyl and allyl ethers of our invention, based on the ultimate end product, is required in the perfume composition, amounts of polyalkyl indanyl n-propyl and allyl ethers of our invention of up to 95% may be used in such perfume compositions.

When used in perfumed articles such as anionic, cationic, nonionic or zwitterionic detergents, or dryer-added fabric softener articles, cosmetic powders or deodorant compositions, from 0.1% up to 5.0% of the polyalkyl indanyl n-propyl and allyl ethers of our invention based on the over-all perfumed article weight may be used in the perfumed articles to impart intense and long-lasting, musky, cigar box-like, amber, woody, patchouli and camphoraceous aromas with woody, winey and balsamic topnotes.

In addition, the perfume compositions of our invention can contain a vehicle or carrier for the polyalkyl indanyl n-propyl and allyl ethers 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 in gelatin or by forming a polymeric shell around a liquid perfume center by means of the use of, for example, a ureaformaldehyde prepolymer.

The following Examples I and II set forth processes for preparing the polyalkyl indanyl n-propyl and allyl ethers of our invention. Example III, et seq. set forth methods for using the polyalkyl indanyl n-propyl and allyl ethers of our invention for their organoleptic properties.

Unless otherwise indicated, all parts and percentages are by weight.
