Abstract
This invention provides smoking compositions which contain a tetracarbonate ester compound as a flavorant additive. In one of its embodiments, this invention provides tobacco compositions which contain a tetracarbonate ester flavorant additive such as 2,5-bis(menthoxycarbonyloxymethylene)-3,6-bis(menthoxycarbonyloxy)-1,4-dio xane: ##STR1## Under cigarette smoking conditions the above illustrated tetracarbonate ester pyrolyzes into menthol and other products which enhance the flavor of the mainstream smoke and the aroma of sidestream smoke.
Claims7
A smoking composition comprising an admixture of (1) combustible filler selected from natural tobacco, reconstituted tobacco and non-tobacco substitutes, and (2) between about 0.0001 and 2 weight percent, based on the total weight of filler, of a tetracarbonate ester flavorant-release additive corresponding to the formula:
- ##STR11## where R is a substituent selected from aliphatic, alicyclic and aromatic radicals.
A method of preparing a smoking composition which is adapted to impart flavoring to the mainstream and sidestream smoke under smoking conditions, which method comprises incorporating into natural tobacco, reconstituted tobacco or non-tobacco substitute between about 0.0001 and 2 weight percent, based on composition weight, of a tetracarbonate ester flavorant-release additive corresponding to the formula:
- ##STR12## where R is a substituent selected from aliphatic, alicyclic and aromatic radicals.
