Flavorant-release additives and compositions containing them
-
, (2008/06/13)
This invention provides smoking compositions which contain a novel heteroaromatic flavorant-release additive as illustrated by the following structure: where R is hydrogen or a C1-C4 alkyl group; R1 is hydrogen or a C1-C8 alkyl group; and R2 is a C3-C12 aromatic substituent; with the proviso that at least two R1 groups are C1-C8 alkyl radicals. Under typical cigarette smoking conditions, 2-isopropylpyrazine and acetophenone are released as pyrolysis products, and enhance the flavor and aroma of the mainstream and sidestream smoke.

Two series of 2-(2-hydroxy-2-phenylethyl)pyrazines were prepared and subjected to pyrolysis conditions (170 degC/diglyme solution).Series A (4a-e) includes substrates in which alkyl groups are placed on the hydroxyalkyl side chain and series B (5a-f) incl
