Abstract:
Hydroformylation of 1-hexene over a series of silica supported noble metal catalysts,HRhCO(TPP)3,HRhCO(TPPTS)3/SiO2 and TPPTS-Rh/SiO2 catalyst were investigated. The results show that the selectivity towards aldehydes and the ratio of liner to branched aldehyde( n/b)over Rh-TPPTS / SiO2 catalyst are near to those of HRhCO(TPPTS)3/SiO2,but much higher than to those of Rh/SiO2 . Under the higher pressure of 7.0 MPa,the TOF of aldehydes on Rh-TPPTS / SiO2 catalyst increase greatly up to 0.0692 S-1 . A possible of catalyst model of Ligands containing lone-pair electron tightly chemically connected to the highly dispersed Rh particles and formation of supported aqueous-film heterogeneous catalyst possessing of homogeneous catalytic performance has been tentatively proposed.

摘要:
考察了几种硅胶负载贵金属催化剂和HRhCO(TPP)3催化剂的1-己烯氢甲酰化反应,对Rh/SiO2、 HRhCO(TPPTS)3/SiO2 和TPPTS-Rh/SiO2上的1-己烯氢甲酰化结果进行了比较.结果表明, TPPTS-Rh/SiO2催化剂的醛的选择性和醛的正异比n/b接近HRhCO(TPPTS)3/SiO2 的相应的催化性能,而远高于Rh/SiO2的相应的催化性能, 7.0 MPa高压下TPPTS-Rh/SiO2催化剂的活性大幅度增加,达到0.0692 S-1.实验排除了其他可能,认为是含有孤
