Abstract: Alkenecarboxylates of the formula I I where R1 is alkyl of 1 to 6 carbon atoms and n is 2, 3 or 4, are prepared by a process which comprises reacting a lactone of the formula II II where R2 is hydrogen or methyl and m is 1 or 2, with an alkanol of 1 to 6 carbon atoms in the presence of an acidic catalyst at from 150 DEG to 400 DEG C.
