Esters of 1,2,3,6-tetrahydrobenzyl alcohol have been found to exhibit powerful odorous notes such as floral, woody and fruity notes, rendering such compounds valuable as fragrance materials either alone or in compositions. These 1,2,3,6-tetrahydrobenzyl alcohol esters are prepared by reacting 1,2,3,6-tetrahydrobenzyl alcohol with an appropriate organic acid.

The present invention provides compounds which upon thermolyis, hydrolysis or both, release an odorant molecule. They find utility, for example, in tobacco, in tobacco paper, and as additives to food, beverages or gum. These compounds are dicarboalkoxy dioxolane derivatives having the following formula: ##STR1## wherein R. sup. 1 and R. sup. 2 are, independently, --CO. sub. 2 R. sup. 3 wherein R. sup. 3 is --H. sub. 3 or lower alkyl, provided that in at least one of R. sup. 1 and R. sup. 2, R. sub. 4 is lower alkyl; wherein Z is a direct bond, or --CH. dbd. C(R. sup. 4)--; where R. sup. 4 is an alkyl group; and Y is, when Z is a direct bond, ##STR2## where R. sup. 5 is lower alkyl; and Y, when Z is --CH. dbd. C(R. sup. 4)--, ##STR3## where R. sup. 6 is H, lower alkyl or OR. sup.

The perfume compositions of this invention contain hexyloxyacetonitrile which contributes unique olfactory properties reminiscent of irone with a flowery, herbaceous by-note. Hexyloxyacetonitrile can be incorporated readily in a wide variety of perfume compositions to enhance, diffuse and prolong the odor characteristics of such compositions.

Alicyclic ketone and alcohol derivatives having the structure: ##STR1## wherein the dotted line represents a carbon-carbon double bond or a carbon-carbon single bond; wherein Z is ##STR2## and wherein each of R. sub. 1, R. sub. 2, R. sub. 3, R. sub. 4, and R. sub. 5 is hydrogen or lower alkyl are useful as odor-modifying ingredients in perfumes and perfumed products and as flavor-modifying ingredients in foodstuffs and tobacco products. These derivatives may be prepared from substituted phenols having the structure: ##STR3##.

The present invention provides organoleptic compositions which upon thermolyis, hydrolysis or both, release an odorant molecule. They find utility, for example, in tobacco, in tobacco paper, and as additives to food, beverages or gum. The compositions contain one or more dicarboalkoxy dioxolane derivatives having the following formula: ##STR1## wherein R. sup. 1 and R. sup. 2 are, independently, --CO. sub. 2 R. sup. 3 wherein R. sup. 3 is --H. sub. 3 or lower alkyl, provided that in at least one of R. sup. 1 and R. sup. 2, R. sup. 3 is lower alkyl; wherein Z is a direct bond, or --CH. dbd. C(R. sup. 4)--; where R. sup. 4 is --H or alkyl group; and Y is ##STR2## where R. sup. 5 and R. sup. 6 are independently --H, lower alkyl or --OR. sup. 7 where R. sup.
