PROCESSES FOR THE CATALYTIC DECARBOXYLATING TRANSCETONIZATION OF ARYL CARBOXYLIC AND ALIFATIC ACIDS AND FOR THE PREPARATION OF AT LEAST ONE FINAL COMPOUND, AND, USE OF THE ARYLALYPHATIC KETONE K

摘要

the present invention relates to a process for the transcetonisation (reaction of piria) between an arylcarboxylic acid and an aliphatic carboxylic acid using a metal-based compound and a light or moderate excess of arylcarboxylic acid. good selectivity, up to 99 mol%, can be achieved. arylaliphatic ketone can be used for the preparation of surfactants and other products downstream.
