PROCESS FOR THE PRODUCTION OF DI-N-PROPYLACETIC ACID

摘要

A process for the preparation of di-n-propyl acetic acid which comprises the steps of A. converting n-valeraldehyde-diallyl acetal into allyl-l-pentenyl ether be cleaving one mol of allyl alcohol per one mol of n-valeraldehye-di-allyl acetal; B. thermally rearranging the allyl-l-pentenyl ether into 2-propyl-pent-4-en-1-al, C. partially hydrogenating the 2-propyl-pent-4-en-1-al catalytically to form 2-propyl valeraldehyde, and D. oxidizing the 2-propyl valeraldehyde to form di-n-propyl acetic acid.
