Abstract
4-Pentenoates are prepared by isomerization by a process in which isomeric pentenoates are treated with a zeolite of the pentasil type at from 50.degree. to 300.degree. C., and the 4-pentenoate is distilled off from the reaction mixture.
Claims11
A process for the preparation of 4-pentenoic esters by the isomerization of 3-pentenoic esters which comprises:
- heating 3-pentenoic esters in a reactor to a temperature of from 50.degree. C. to 300.degree. C. in the presence of a zeolite catalyst having a pentasil structure, and
- distilling off from the reaction mixture the 4-pentenoic esters that are formed.
