摘要:
In one embodiment this invention provides smoking compositions which contain a novel oxalate ester flavorant-release additive.Under cigarette smoking conditions, a combustible filler additive such as methyl 2-pyrazinyl-2-propanyl oxalate or di(2-pyrazinyl-2-propanyl) oxalate pyrolyzes and releases 2-isopropenylpyrazine flavorant as a volatile component of the cigarette smoke. ##STR1##
