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.
本发明提供了含有新型杂芳香族香料释放添加剂的烟用组合物,其结构如下:
其中 R 是氢或 C₁-C₄ 烷基;R¹ 是氢或 C₁-C₈ 烷基;R² 是 C₃-C₁₂ 芳族取代基;但至少有两个 R¹ 基团是 C₁-C₈ 烷基。
在典型的香烟吸食条件下,2-异丙基吡嗪和苯乙酮会作为热分解产物释放出来,并增强主流烟和副流烟的味道和香气。
