ABSTRACT:
Described is a mixture containing a major proportion of unsaturated aldehydes defined according to the structure: ##STR1## wherein in the mixture in each of the molecules thereof one of the dashed lines represents a carbon-carbon double bond and each of the other of the dashed lines represent carbon-carbon single bonds, prepared by first reacting a diisoamylene compound defined according to the structure: ##STR2## wherein one of the dashed lines represents a carbon-carbon double bond and each of the other of the dashed lines represent carbon-carbon single bonds or defined according to one of the structures: ##STR3## with formaldehyde or a formaldehyde source such as trioxane or paraformaldehyde in the presence of an alkanoic acid anhydride and an acid catalyst; then hydrolyzing the resulting ester or mixture of esters to form an alcohol or mixture of alcohols and finally oxidizing the resulting alcohol or mixture of alcohols to form a mixture of aldehydes; the organoleptic uses of such oxidation products in the field of perfumery, colognes and perfumed articles (e.g., solid or liquid anionic, cationic, nonionic, zwitterionic detergents, fabric softener compositions or dryer-added fabric softener articles).
