Progress in Research of Catalytst System Stability for Oxo Synthesis

综述了烯烃羰基合成反应中金属铑催化体系稳定性的研究进展,分别介绍了羰基合成反应催化体系中有机膦配体经过氧化或水解而变质的历程和铑络合物催化剂失活的原理,并重点介绍了目前国内外围绕设计合成稳定的配体和通过添加剂抑制催化剂失活而提出的保持羰基合成反应中催化体系稳定的方案,分析了各种方案的利弊,并对今后的发展方向进行了展望。

The study on the stability of rhodium catalyst systems used in oxo synthesis of olefins was reviewed. The degradation of organo-phosphrous ligands through oxidation or hydrolysis and the deactivation mechanism of the rhodium complex catalysts were discussed. The ways for stabilizing the rhodium catalyst systems included searching for more stable ligands and additives used to inhibit the deactivation. Many approaches based on these ideas were introduced, and their advantages and disadvantages were analyzed.
