Abstract
In one of its embodiments the present invention provides a smoking composition which contains a novel type of acylpyrazine ether flavorant additive as exemplified by 1-(3-methoxy-2-pyrazinyl)-2-methyl-1-propanone: ##STR1##
Claims7
A smoking composition comprising an admixture of (1) combustible filler selected from natural tobacco, reconstituted tobacco, non-tobacco substitutes, and mixtures thereof, and (2) between about 0.00001 and 2 weight percent, based on the total weight of filler of an acylpyrazine ether corresponding to the formula:
- ##STR19## where R is a substituent selected from aliphatic, alicyclic and aromatic groups containing between about 2-12 carbon atoms, R.sup.1 is a substituent selected from hydrogen and alkyl groups containing between about 1-6 carbon atoms, X is etheric oxygen or sulfur, and R.sup.2 is a substituent selected from aliphatic, alicyclic and aromatic groups containing between about 1-12 carbon atoms, with the proviso that the position-(3) substituent is not hydrogen.
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, non-tobacco substitute or mixtures thereof between about 0.00001 and 2 weight percent, based on composition weight, of acylpyrazine ether flavorant additive corresponding to the formula:
- ##STR20## where R is a substituent selected from aliphatic, alicyclic and aromatic groups containing between about 2-12 carbon atoms, R.sup.1 is a substituent selected from hydrogen and alkyl groups containing between about 1-6 carbon atoms, X is etheric oxygen or sulfur, and R.sup.2 is a substituent selected from aliphatic, alicyclic and aromatic groups containing between about 1-12 carbon atoms, with the proviso that the position-(3) substituent is not hydrogen.
