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.7 is --H or lower alkyl.
本发明提供了一种感官组合物,当进行热解、水解或两者同时进行时,释放出一种气味分子。例如,在烟草、烟草纸和作为食品、饮料或口香糖添加剂中,它们具有实用性。该组合物含有一个或多个二羧基烷氧基二噁烷衍生物,其具有以下式子:##STR1## 其中R1和R2是独立的--CO2R3,其中R3是--H3或低碳基,但在R1和R2中至少有一个,R3是低碳基;其中Z是直接键或--CH.dbd.C(R4)--;其中R4是--H或烷基;而Y是##STR2##其中R5和R6是独立的--H、低碳基或--OR7,其中R7是--H或低碳基。
