Referring to FIGS. 16 and 17, there is provided a process for forming scented polymer elements (wherein the polymer may be a thermoplastic polymer such as low density polyethylene or polypropylene or copolymers of ethylene and vinyl acetate or mixtures of polymers and copolymers such as copolymers of ethylene and vinyl acetate and polyethylene) such as pellets useful in the formation of plastic particles useful in fabricating certain articles which may be perfumed. This process comprises heating the polymer or mixture of polymers to the melting point of said polymer or mixture of polymers, e.g., 250.degree. C. in the case of low density polyethylene. The lower most portion of the container is maintained at a slightly lower temperature and the material in the container is taken off at such location for delivery through the conduit (indicated by reference numeral 218). Thus, referring to FIGS. 16 and 17, in particular, the apparatus used in producing such elements comprises a device for forming the polymer containing perfume, e.g., polyethylene or polyethylene-polyvinyl acetate or mixtures of same or polypropylene, which comprises a vat or container 212 into which the polymer taken alone or in admixture with other copolymers and the perfuming substance which is at least one of the methyl substituted hexahydroindanols and alkyl ethers thereof of our invention and other compatible perfumes is placed. The container is closed by means of an air-tight lid 228 and clamped to the container by bolts 265. A stirrer 273 traverses the lid or cover 228 in an air-tight manner and is rotatable in a suitable manner. A surrounding cylinder 212A having heating coils which are supplied with electric current through cable 214 from a rheostat or control 216 is operated to maintain the temperature inside the container 212 such that the polymer in the container will be maintained in the molten or liquid state. It has been found advantageous to employ polymers at such a temperature that the viscosity will be in the range of 90-100 Sayboldt seconds. The heater is operated to maintain the upper portion of the container 212 within a temperature range of, for example, 220.degree.-270.degree. C. in the case of low density polyethylene. The bottom portion of the container 212 is heated by means of heating coils 212A regulated through the control 220 connected thereto through a connecting wire 222 to maintain the lower portion of the container 212 within a temperature range of 220.degree.-270.degree. C.
Thus, the polymer or mixture of polymers added to the container 212 is heated from 10-12 hours, whereafter the perfume composition or perfume material which contains one or more of the methyl substituted hexahydroindanols and alkyl ethers thereof of our invention is quickly added to the melt. Generally, about 10-45% by weight of the resulting mixture of the perfumery substance is added to the polymer.
After the perfume material is added to the container 212, the mixture is stirred for a few minutes, for example, 5-15 minutes and maintained within the temperature ranges indicated previously by the heating coils 212A. The controls 216 and 220 are connected through cables 224 and 226 to 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 conduit 232 (also shown by reference numeral 218 (in cutaway cross section)) having a multiplicity of orifices 234 adjacent to the lower side thereof. The outer end of the conduit 232 is closed so that the liquid polymer in intimate admixture with one or more of the methyl substituted hexahydroindanols and alkyl ethers thereof of our invention and one or more other substances (if desired) will continuously drop through the orifices 234 downwardly from the conduit 232. During this time, the temperature of the polymer intimately admixed with the perfumery substance in the container 212 is accurately controlled so that a temperature in the range of from about 240.degree.-250.degree. C., for example (in the case of low density polyethylene) will exist in the conduit 232. The regulation of the temperature through the controls 216 and 220 is essential in order to insure temperature balance to provide for the continuous dripping or dropping of molten polymer intimately admixed with the perfume substance which is all of or which contains one or more of the methyl substituted hexahydroindanols and alkyl ethers thereof of our invention, through the orifices 234 at a rate which will insure the formation of droplets 236 which will fall downwardly onto a moving conveyor belt 238 caused to run between conveyor wheels 240 and 242 beneath the conduit 232.
When the droplets 236 fall onto the conveyor 238, they form pellets 244 which harden almost instantaneously and fall off the end of the conveyor 238 into a container 245 which is advantageously filled with water 252 or some other suitable cooling liquid to insure the rapid cooling of each of the pellets 244. The pellets 244 are then collected from the container 245 and utilized for the formation of other functional products, e.g., garbage bags and the like.
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.

No. 3,681,464 issued on Aug. 1, 1972 (title: "SATURATED INDANE DERIVATIVES AND PROCESSES FOR PRODUCING SAME") wherein the reaction sequence: ##STR60##
The mixture of compounds defined according to the structure: ##STR61## uses as a starting material the mixture of compounds defined according to the structure: ##STR62## prepared according to the reaction sequence: ##STR63## the details for which are disclosed in the above-mentioned U.S. Pat. No. 3,681,464 issued on Aug. 1, 1972, the specification for which is incorporated by reference herein.
With reference to preparing the methyl substituted hexahydroindanols and alkyl ethers thereof of our invention defined according to the structure: ##STR64## the mixture of ketones defined according to the structure: ##STR65## is reacted with an organometallic compound having the structure:
(R.sub.1).sub.p M'"
wherein R.sub.1 is methyl or ethyl; wherein P is the valence of M'" which is 1 or 2; wherein M'" is a methyl or metal halide, M or M'; wherein M represents Li or MgX; wherein X is chloro, bromo or iodo; wherein M' is a bivalent metal, cadmium or zinc. Thus the compound having the structure:
(R.sub.1).sub.p M'"
may either be a compound having the structure:
R.sub.1 --M
in the case of monovalent metals or metal halides, or the compound having the structure: ##STR66## in the case of bivalent metals. The reaction takes place at low temperatures, e.g., -10.degree. C. up to +10.degree. C. in the presence of a solvent which is inert to the reactants, that is, diethyl ether (anhydrous) or tetrahydrofuran (anhydrous).
This reaction is set forth as follows: ##STR67##
The resulting organometallic salt having the structure: ##STR68## is then hydrolyzed in the presence of an acid, such as dilute hydrochloric acid or dilute ammonium chloride according to the reaction: ##STR69## The resulting alcohol defined according to the structure: ##STR70## is then etherified with an alkyl halide defined according to the structure:
R.sub.7 --Y
wherein R.sub.7 is C.sub.1 -C.sub.3 alkyl, that is, methyl, ethyl, n-propyl or isopropyl and Y represents chloro, bromo or iodo according to the reaction sequence: ##STR71## wherein R.sub.1 " represents hydrogen, methyl or ethyl. It is to be noted then that the mixtures defined according to the structure: ##STR72## and the methyl substituted hexahydroindanols and alkyl ethers thereof defined according to the structure: ##STR73## can both be prepared in this manner.
In carrying out the etherification reaction, the mixture of compounds defined according to the structure: ##STR74## or the compounds defined according to the structure: ##STR75## are first reacted with an alkali metal hydride having the formula:
M".sup.+- H
wherein M" is sodium or potassium according to the reaction: ##STR76## wherein R.sub.1 " is hydrogen, methyl or ethyl and R.sub.2, R.sub.3, R.sub.4, R.sub.5 and R.sub.6 are defined, supra. The resulting salt having the structure: ##STR77## is then reacted with the etherifying reagent having the structure:
R.sub.7 --Y
wherein R.sub.7 and Y have been defined, supra, according to the reaction: ##STR78##
With respect to the Grignard reaction, the organometallic salt formed when the reagent: ##STR79## is reacted with a ketone or mixture of ketones defined according to the structure: ##STR80## has the following structure: ##STR81## whereas when the Grignard reaction is carried out using the Grignard reagent having the structure:
R.sub.1 --M,
the salt having the structure: ##STR82## is formed. Both of the foregoing compounds are shown by the structure: ##STR83## wherein M'", P, R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5 and R.sub.6 have been defined, supra.
The Grignard reaction is carried out in the presence of an inert solvent such as tetrahydrofuran or diethyl ether as set forth, supra. The reaction temperature may vary between -10.degree. C. and +10.degree. C. for the formation of the salt, and the reaction temperature may vary between about 15.degree. C. up to about 30.degree. C. for the hydrolysis reaction. The mole ratio of ketone:Grignard reagent is preferably slightly greater than 1:1 in favor of the ketone (that is, where the ketone reactant is in excess). The concentration of Grignard reagent in solution (that is, in the inert solvent) may vary from about 0.5 up to about 1 mole per liter. In the hydrolysis reaction, other acidic medium may be used, for example, dilute acetic acid.
With respect to the etherification procedure, the mole ratio of alkali metal hydride:alcohol is preferably slightly greater than 1:1 in favor of the alkali metal hydride. Preferably the mole ratio of alkali metal hydride:alcohol is about 1.3:1. The reaction also takes place in the presence of an inert solvent such as tetrahydrofuran or diethyl ether, and the alkali metal hydride is used in solution wherein the solvent is the inert solvent, e.g., tetrahydrofuran. The reaction temperature for the formation of the alkali metal salt is in the range of from about 65.degree.-75.degree. C. The time of reaction is between about 3 hours and about 5 hours.
With respect to the reaction of the etherifying reagent with the resulting salt, the temperature of reaction is between about 75.degree. C. and about 80.degree. C. and the time of reaction is between about 5 and 15 hours. The reaction of the etherification reagent with the salt also takes place in the presence of an inert solvent, which is the same solvent as the one for the formation of the salt, e.g., tetrahydrofuran or diethyl ether. If an inert solvent such as diethyl ether is used when using the higher reaction temperatures, higher pressures must be employed; that is, super atmospheric pressures, e.g., 5-10 atmospheres. The reaction using the tetrahydrofuran solvent may take place at 1 atmosphere.
At the end of the reaction, the reaction mass is quenched with water and extracted with solvent, such as diethyl ether. The extract is stripped of solvent and distilled preferably by means of fractional distillation. The resulting fractions are bulked and utilized for their organoleptic properties.

At least one of the methyl substituted hexahydroindanols and alkyl ethers thereof of our invention prepared in accordance with the process of our invention and one or more auxiliary perfume ingredients including, for example, alcohols other than the methyl substituted hexahydroindanols and alkyl ethers thereof of our invention, aldehydes, ketones, terpenic hydrocarbons, nitriles, esters, lactones, ethers other than the methyl substituted hexahydroindanols and alkyl ethers thereof of our invention, 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 and preferably in the piney and patchouli fragrance areas. Such perfume compositions usually contain (a) the main note or "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 overall sensory effect of the perfume composition will be at least the sum total of the effects of each of the ingredients. Thus, at least one of the methyl substituted hexahydroindanols and alkyl ethers thereof of our invention prepared in accordance with the processes 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 at least one of the methyl substituted hexahydroindanols and alkyl ethers thereof of our invention prepared in accordance with the processes of our invention which will be effective in perfume compositions as well as in perfumed articles (e.g., anionic, nonionic, cationic or zwitterionic detergents, soaps, fabric softener compositions and articles, and hair preparations) and colognes 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 0.01% of at least one of the methyl substituted hexahydroindanols and alkyl ethers thereof of our invention prepared in accordance with the processes of our invention or even less (e.g., 0.005%) can be used to impart a woody, amber, cedarwood, fresh cut cedarwood, fruity, bois ambrene, limlewood (fir), green, green wood, balsamic, cassis, juniper, animalic, camphoraceous, musky, jasmine and fatty aroma with woody, cedarwood, amber, fruity, sandalwood, musky, kephalis, green and balsamic topnotes to soaps, cosmetics, anionic, nonionic, cationic or zwitterionic detergents, fabric softener compositions, fabric softener articles, perfumed polymers and the like. The amount employed can range up to 70% of the fragrance components and will depend on considerations of cost, nature of the end product, the effect desired on the finished product and the particular fragrance sought.
One or more of the methyl substituted hexahydroindanols and alkyl ethers thereof of our invention prepared in accordance with the processes of our invention are useful (taken alone or 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 creams, deodorants, hand lotions and sun screens; powders such as talcs, dusting powders, face powders, perfumed polymers and the like.
When used as (an) olfactory component(s), as little as 0.2% of one or more of the methyl substituted hexahydroindanols and alkyl ethers thereof of our invention prepared in accordance with the processes of our invention will suffice to impart an intense and long lasting, woody, amber, cedarwood, fresh cut cedarwood, fruity, bois ambrene limlewood (fir), green, green wood, balsamic, cassis, juniper, animalic, musky, camphoraceous, jasmine and fatty aroma with woody, cedarwood, amber, fruity, sandalwood, musky, kephalis, green and balsamic topnotes to patchouli, vetiver and pine formulations. Generally, no more than 6% of one or more of the methyl substituted hexahydroindanols and alkyl ethers thereof of our invention prepared in accordance with the processes of our invention based on the ultimate end product are required in the perfumed article composition. Accordingly, the range of the use of the methyl substituted hexahydroindanols and alkyl ethers thereof of our invention in a perfumed article may vary from about 0.2% up to about 6% by weight of the ultimate perfumed article.
In addition, the perfume compositions or fragrance compositions of our invention can contain a vehicle or carrier for one or more of the methyl substituted hexahydroindanols and alkyl ethers thereof of our invention prepared in accordance with the processes of our invention.
