PROCESS FOR THE CARBONYLATION OF ETHYLENE

A PROCESS FOR THE LIQUID-PHASE CARBONYLATION OF ETHYLENE IN THE PRESENCE OF A CATALYST SYSTEM COMPRISING A GROUP VIII METAL OR COMPOUND THEREOF, A PHOSPHINE LIGAND AND A SOURCE OF ANIONS, AND IN THE PRESENCE OF A SOURCE OF HYDROXYL GROUPS, IS CARRIED OUT IN CONDITIONS IN WHICH THE MOLAR RATIO OF ETH...

Zusammenfassung:	A PROCESS FOR THE LIQUID-PHASE CARBONYLATION OF ETHYLENE IN THE PRESENCE OF A CATALYST SYSTEM COMPRISING A GROUP VIII METAL OR COMPOUND THEREOF, A PHOSPHINE LIGAND AND A SOURCE OF ANIONS, AND IN THE PRESENCE OF A SOURCE OF HYDROXYL GROUPS, IS CARRIED OUT IN CONDITIONS IN WHICH THE MOLAR RATIO OF ETHYLENE TO CARBON MONOXIDE IN THE GASEOUS PHASE OF THE REACTOR IS GREATER THAN 1: 1 AND PREFERABLY GREATER THAN 5:1. THE HIGHER RATIOS OF ETHYLENE TO CARBON MONOXIDE ARE BENEFICIAL IN INCREASING THE TURNOVER NUMBER OF THE CATALYST SYSTEM.
