Abstract

A METHOD COMPRISES CONTINUOUSLY SUPPLYING AN ALCOHOL TO A PRESSURIZED REACTION SYSTEM, PRESSURIZING CARBON MONOXIDE WITH A COMPRESSOR 8 ATTACHED TO A FIRST FEED LINE 22, FOR CONTINUOUSLY SUPPLYING CARBON MONOXIDE TO THE REACTION SYSTEM VIA A SECOND FEED LINE 23 WITH A REFERENCE FLOW RATE F, AND CONVERGING EXCESS CARBON MONOXIDE IN THE REACTION SYSTEM IN THE FIRST FEED LINE VIA A BRANCHED CIRCULATION LINE 24 FOR ALLOWING TO REACT ALCOHOL WITH CARBON MONOXIDE. THE REFERENCE FLOW RATE F IN THE SECOND FEED LINE 23 IS A TOTAL RATE OF A REFERENCE CONSUMPTION FLOW RATE FCS IN THE REACTION AND A FLOW RATE F1 IN EXCESS RATE OVER A FLUCTUATION CONSUMPTION FLOW RATE ( )FCV IN THE REACTION SYSTEM (F=FCS+F1, F1> ( )FCV). ACCORDING TO THE PRESSURE FLUCTUATION OF THE GASEOUS PHASE IN THE REACTION SYSTEM, THE FLOW RATE IN THE CIRCULATION LINE 24 IS CONTROLLED TO A FLOW RATE FR=F1-( )FCV AND THE FEED FLOW RATE IN THE FIRST FEED LINE 22 IS CONTROLLED TO A FLOW RATE FSU=FCS+ ( )FCV, FOR COMPENSATING A CONSUMPTION RATE VARIATION IN THE REACTION SYSTEM WITH THE FEED FLOW RATE OF CARBON MONOXIDE. THIS ENSURES DISCHARGE INHIBITION OF THE GASEOUS REACTANT IN A LIQUID PHASE PRESSURIZED REACTION SYSTEM (SUCH AS CARBONYLATION REACTION SYSTEM) AND EFFECTIVE UTILIZATION THE REACTANT FOR THE REACTION.
