PROCESS FOR THE PREPARATION OF UNSATURATED ALCOHOLS AND/OR OF THEIR ESTERS

摘要

Process for the preparation of unsaturated alcohols and/or esters thereof by reacting conjugated dienes with water and/or aqueous carboxylic acid solutions in the presence of a macroporous acid ion exchanger and suitable solvents. The diene has the general formula I (I) in which R1, R2 and R3 are hydrogen or a methyl group and R2 also can represent an aliphatic hydrocarbon radical having 2 to 6 carbon atoms which may contain a double bond which is not in a conjugated position relative to the double bonds of the diene, and preferably R1 and R3 each represent groups CH3 or CH2-CH3. Said diene is reacted in a homogeneous or quasi-homogeneous phase in the presence of said macroporous acid ion exchanger.
