PROCESS FOR THE CARBONYLATION OF ETHYLENE |
摘要 |
A process for the liquid-phase carbonylation of ethylene in the presence of a catalyst system comprising a Group VIII metal or I 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.
