A PROCESS FOR THE PREPARATION OF AN ALKYL ALKENOATE

A process for the preparation of an alkyl alkenoate, wherein a lactone of the general molecular formula (I) wherein n is 1, 2 or 3, R1 is a C1-C4 alkyl group, and R2, R3 and R4 are, independently, a H atom or a C1-C4 alkyl group, is reacted with a C1-C4 alkyl alcohol in a liquid phase in the presence of a strong acid catalyst at transesterification conditions to form the alkyl alkenoate, wherein alkyl alkenoate and alcohol are continuously removed from the liquid phase by distillation.
