摘　　要：催化剂是一种以铑基团为主要活性中心的贵金属铑催化剂,具有高选择性、高活性及反应条件温和等良好性能,但在羰基合成反应的使用过程中,工艺反应会受到中毒和环境等多种因素的影响,导致铑的形态发生改变,使其从单体铑转变为不太活跃的铑团簇,从而降低催化剂溶液的活性,本文对铑催化剂失活原因进行了具体分析。Rhodium catalyst is a noble metal catalyst with rhodium group as the main active center,which has good performance such as high selectivity,high activity and mild reaction conditions,but during the use of rhodium catalyst for carbonyl synthesis,the process reaction will be affected by a variety of factors,such as poisoning and the environment,which leads to a change in the morphology of rhodium,which changes it from monomeric rhodium to less active rhodium clusters,thus reducing the activity of the catalyst solution.In this paper,the causes of deactivation of ROPAC catalysts are specifically analyzed.
