The reduction reaction is preferably carried out in the presence of a solvent such as isopropyl alcohol under reflux conditions. At the end of the reaction, the reaction mass is neutralized and then fractionally distilled to yield the resulting primary alcohol which may be used as is for its organoleptic properties; or the primary alcohol may be further reacted, for example, to form esters according to the generic reaction: wherein R 7 is C 1 -C 3 lower alkyl and wherein Y represents oxyacyl, chloro or bromo; more specifically, for example, according to the reaction: Such esterification reactions in order to form esters defined according to the generic structure: or, more specifically, for example, the compound having the structure are carried out under conditions well known to those having ordinary skill in the art; for example, as exemplified in Example X, infra, using an acetic anhydride reagent under reflux conditions (approximately 110°C) for a period of time of between about 0.5 hours up to about 3 hours. At the end of the reaction, the reaction mass is neutralized with, for example, aqueous sodium carbonate, and the resulting product is dried and fractionally distilled. The resulting ester defined according to the structure: more specifically, for example, defined according to the structure: may then be used as is for its organoleptic properties or further reacted by means of transesterification whereby the ester moiety is replaced with a different ester moiety totally or in part (for example, whereby a mixture of acetate and butyrate esters is formed). The transesterification conditions are well known to those having ordinary skill in the art. If the initial oxo reaction is carried out whereby a mixture of stereoisomers or a stereoisomer having an enantiomeric excess of greater than 50%, [EE%>50%], for example having an enantiomeric excess percent of 90%, [EE%=90%], then the resulting reaction products as set forth, supra, will have the same enantiomeric excess and will have the same specific optical rotation. The trans:cis mixture of compounds having the structures: and in a 9:1 ratio, has a velvety, diffusive, sweet, rich, warm, intense musk, spicy, woody, balsamic, earthy, rooty and vetiver-like aroma with animalic, costus topnotes and sweet, musky, spicy, floral undertones.

The bottom portion of the container 212 is heated by means of heating coils 212A heated through a control 220 connected thereto through a connecting wire 226 to maintain the lower portion of the container 212 within a temperature range of from 250-350°F. Thus, polymer (e.g., polyolefin) added to the container 212 is heated from 10-12 hours whereafter a scent or aroma imparting material which contains or consists of at least one of the 4,5,6,7-tetrahydro-polyalkylated-4-indane carbinols, carbinyl esters, carboxaldehydes, ketones and cyanides of our invention is quickly added to the melt. The material must be compatible with the polyolefin and forms a homogeneous liquid melt therewith. The scented material containing or consisting of at least one of the 4,5,6,7-tetrahydro-polyalkylated-4-indane carbinols, carbinyl esters, carboxaldehydes, ketones and cyanides of our invention is of a type for the particular aroma desired and formulated specifically for the scenting purpose for which the polyolefin will be employed. The heat resisting coils and aromatic materials in some instances in solid or powdered form, may be employed or added to the polyolefin in the container 212 . Generally, about 10-30% by weight of the scenting material is added to the polyolefin. After the scent imparting material containing or consisting of at least one of the 4,5,6,7-tetrahydro-polyalkylated-4-indane carbinols, carbinyl esters, carboxaldehydes, ketones and cyanides of our invention 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. The controls 216 and 220 are connected to the heating coils 212A respectively, through wires 214 and 222 . Thereafter, the valve "V" is opened permitting the mass to flow outwardly through conduit 232 (shown in cross section by reference numeral 218) 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 (e.g., polyolefin or polyurethane, which is thermoplastic) and aroma imparting mixture (containing at least one of the 4,5,6,7-tetrahydro-polyalkylated-4-indane carbinols, carbinyl esters, carboxaldehydes, ketones and cyanides of our invention) will continuously drop through the orifices 234 downwardly from the conduit 232 . During this time, the temperature of the polymer (e.g., polyolefin or thermoplastic polyurethane) and aroma mixture containing at least one of the 4,5,6,7-tetrahydro-polyalkylated-4-indane carbinols, carbinyl esters, carboxaldehydes, ketones and cyanides of our invention in the container 212 is accurately controlled so that a temperature in the range of from about 210-275°F will exist 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 molten polymer (e.g., polyolefin or thermoplastic polyurethane) and scenting material containing or consisting of at least one of the 4,5,6,7-tetrahydro-polyalkylated-4-indane carbinols, carbinyl esters, carboxaldehydes, ketones and cyanides 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 trained 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 or some other suitable cooling liquid in order to insure the rapid cooling of each of the pellets. The pellets 244 are then collected from the container 245 and utilized in a process as illustrated, infra. A feature of this aspect of the process of our invention is the provision for moistening the conveyor belt 238 to insure rapid formation of the solid polymer (e.g., polyolefin or thermoplastic polyurethane) scented pellets 244 without sticking to the belt. The belt 238 is advantageously of a material which will not normally stick to a melted plastic, 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 254 to maintain a level for moistening a sponge element 256 which bears against the exterior surface of the belt 238 . The following Examples I-XI serve to illustrate the processes for preparing the compounds of our invention and the compounds useful for their organoleptic properties. Examples following Example XI (Examples XII, et seq.) illustrate organoleptic utilities of the 4,5,6,7-tetrahydro-polyalkylated-4-indane carbinols, carbinyl esters, carboxaldehydes, ketones and cyanides of our invention. All parts and percentages given herein are by weight unless otherwise specified. The invention is not to be limited to the examples, but is only limited by the scope of the claims appended hereto.
