Process for producing mixture containing 4-(4{40 -methyl-4{40 -hydroxyamyl)-{66 {hu 3{b -cyclohexene carboxaldehyde

摘要

A process is described for reacting "myrac aldehyde" having the structure: <IMAGE> (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 DEG up to 120 DEG C, to produce a mixture containing a major proportion of 4-(4'-methyl-4'-hydroxyamyl)- DELTA 3-cyclohexene carboxaldehyde and a minor proportion of 3-(4'-methyl-4'-hydroxyamyl)- DELTA 3-cyclohexene carboxaldehyde (otherwise termed "Lyral") having the structure: <IMAGE> and a minor proportion of 3-(4'-methyl-4'-hydroxyamyl)- DELTA 3-cyclohexene carboxaldehyde having the structure: <IMAGE> 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.
