PROCESS FOR THE PRODUCTION OF VINYL ACETATE

摘要

IN PROCESS FOR THE PRODUCTION OF VINYL ACETATE IN WHICH ETHYLENE, ACETIC ACID AND OXYGEN-CONTAINING GAS ARE COMBINED AT ELEVETED TEMPERATURE IN THE PRESENCE OF A CATALYST MATERIAL TO PRODUCE (i) A PRODUCT MIXTURE COMPRISING VINYL ACETATE, (ii) ALIQUID BY-PRODUCT COMPRISING ACETIC ACID AND WATER AND (iii) A GESEOUS BY-PRODUCT COMPRISING CARBON DIOXIDE, THE LIQUID BY-PRODUCT IS SEPARATED FROM THE PRODUCT MIXTURE AND TREATED TO REDUCED THEWATER CONTENT THEREIN BEFORE BEING RECYCLED TO THE REACTOR SUCH THAT THE AMOUNT OF WATER ENTERING THE REACTOR COMPRISES LESS THAN 6WT400237C8REFERABLY LESS THAN 4 WTMORE, PREFERABLY LESS THAN 3 WTOF THE TOTAL OF ACETIC ACID AND WATER ENTERING THE REACTOR.
