目前,在甲醇羰基化反应中,多采用均相催化体系,但由于反应产物的分离及催化剂的回收比较繁锁,给工业化生产带来了许多困难。甲醇羰基化反应催化剂的多相化,引起了人们的极大兴趣。然而由于这类催化剂的活性低,铑从载体表面上易于流失以及其他因素,到目前为止,仍未得到比较满意的结果 At present, the homogeneous catalytic system is mostly used in the carbonylation of methanol. However, due to the separation of the reaction products and the cumbersome recovery of the catalyst, many difficulties are brought about for industrialized production. Methanol carbonylation catalyst heterogeneity has aroused great interest. However, due to the low activity of such catalysts, the loss of rhodium from the support surface and other factors, so far no satisfactory results have been obtained
