Abstract:
Described is a process for augmenting or enhancing the aroma of a nonionic, anionic or cationic solid or liquid detergent comprising the step of intimately admixing with a solid or liquid anionic, cationic or nonionic detergent base a composition comprising from about 80% up to about 98% of trans, trans-delta-damascone and from about 2% up to about 20% of cis, trans-delta-damascone or substantially pure trans, trans-delta-damascone.
Abstract:
Processes and compositions are described for the use in tobacco flavor and aroma and perfume aroma augmenting, modifying, enhancing and imparting compositions and as tobacco, perfume, cologne and perfumed article aroma imparting materials of 1-(2,6,6-trimethyl-1,3-cyclohexadien-1-yl)-1,3-butanedione which has the structure: ##STR1## which also, in its enolate form, has the structure: ##STR2##
Abstract:
Described is a process for preparing an equilibrium mixture containing 1-(2,6,6-trimethyl-1,3-cyclohexadien-1-yl)-1,3-butanedione and its enol, which equilibrium mixture contains compounds having the structures: ##STR1## which process involves first reacting a methyl magnesium halide with 1-acetyl-2,6,6-trimethyl-1,3-cyclohexadiene to form a first organometallic compound; reacting the first organometallic compound with an acetyl halide to form a second organometallic compound, a novel intermediate; and then reacting said second organometallic compound with a hydrolyzing agent such as aqueous acid to form said equilibrium mixture.
