ABSTRACT:
A process is described for reacting "myrac aldehyde" having the structure: ##STR1## (which structure is representative of a mixture of two compounds, one where the carboxaldehyde is in the "4" position and the other wherein the carboxaldehyde is in the "5" position) with an acid hydrating agent at a temperature of from 0.degree. up to 120.degree. C, to produce a mixture containing a major proportion of 4-(4'-methyl-4'-hydroxyamyl)-.DELTA..sup.3 -cyclohexene carboxaldehyde and a minor proportion of 3-(4'-methyl-4'-hydroxyamyl)-.DELTA..sup.3 -cyclohexene carboxaldehyde (otherwise termed "Lyral") having the structure: ##STR2## and a minor proportion of 3-(4'-methyl-4'-hydroxyamyl)-.DELTA..sup.3 -cyclohexene carboxaldehyde having the structure: ##STR3## which mixture possesses a sweet, lilac-lily aromatic odor and isolating a mixture of the two carboxaldehydes. The products produced by the aforementioned process are useful in various aspects of perfumery.
