利用动力学实验装置及加温加压“原位”红外光谱和紫外光谱等检测手段,研究了氧、氯、硫及其化合物对铑膦络合物催化丙烯氢甲酰化反应的影响及作用机理。实验表明,上述物质能与催化剂的配位体三苯基膦及铑中心金属发生反应,其结果破坏了催化剂的活性结构,导致催化剂失活。不同的氯化物和硫化物对催化性能影响程度有明显差别。实验并证明,氧中毒是暂时性的,而氯中毒是永久性的。 The effects of oxygen, chlorine, sulfur and their compounds on the catalytic hydroformylation of propene with rhodium-phosphine complexes were studied by means of kinetic experimental equipment and “in-situ” infrared spectroscopy and ultraviolet spectroscopy at elevated temperature and pressure. mechanism. Experiments show that the above substances can react with the ligand of the catalyst triphenylphosphine and rhodium center metal, resulting in the destruction of the active structure of the catalyst, resulting in deactivation of the catalyst. Different chlorides and sulfides have significant differences on the catalytic performance. Experiments have shown that oxygen poisoning is temporary and that chlorine poisoning is permanent.
