PROCESS FOR ISOMERIZATION OF LACTONES INTO PENTENOIC ACIDS BY ACID OR BASIC CATALYSIS BY ACID OR BASED CATALYST

摘要

The present invention relates to lactones, more particularly to a process for isomerizing different valerolactones and their isomers to pentenic acid.;More particularly, the present invention relates to a process for the preparation of acidic solid catalysts or basic metal phosphates, basic metal oxides, basic metal oxides, metal oxides, metal oxides, metal oxides, metal oxides and metal oxides selected from acidic molecular sieves, clays, bridges, clays Carbonates and basic molecular sieves selected from the group consisting of carbonates and basic molecular sieves.
