摘要:
Alkenecarboxylates of the formula I ##STR1## where R.sub.1 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 ##STR2## where R.sub.2 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.degree. to 400.degree.
