DEHYDRATION PROCESS USING ACETIC ANHYDRIDE OF WET METHYL ACETATE AND ITS APPLICATION TO THE CARBONYLATION OF METHYL ACETATE

摘要

P THE INVENTION CONCERNS THE DEHYDRATION OF METHYL ACETATE USING ACETIC ANHYDRIDE. /P P THIS PROCESS MAY BE PART OF A CARBONYLATION PROCESS OF ANHYDROUS ACETATE, WHICH PRODUCES THE ACETIC ANHYDRIDE NECESSARY FOR DEHYDRATION, AND MORE GENERAL TO A PROCESS FOR OBTAINING METHYL ACETATE BY ESTERIFICATION OF ACETIC ACID BY CHOH IN AN ESTERIFICATION ZONE, THEN DEHYDRATION AND CARBONYLATION OF METHYL ACETATE GIVING ACETIC ANHYDRIDE. /P P DEPENDING ON THE PROPORTIONS INTRODUCED IN THE GLOBAL PROCESS, THAT MAY PROVIDE VARIOUS INTERMEDIATES OF ORGANIC SYNTHESIS. /P
