摘　　要：探究了催化剂预活化对均相催化剂体系进行1-辛烯氢甲酰化反应的影响,并从预活化温度、预活化时间和预活化气氛等方面考察了铑/双膦催化剂体系用于氢甲酰化反应的作用效果。结果表明,对催化剂体系进行预活化有利于提高烯烃转化率和醛选择性,进而增加醛收率,但当预活化温度超过70℃,预活化时间为20 min时醛选择性开始下降。此外,在合成气气氛下进行预活化在一定程度上有利于生成催化剂活性中心。The effect of catalyst preactivation on the hydroformylation of 1-octene in homogeneous Rh/diphosphine catalyst system has been investigated in terms of preactivation temperature,preactivation time and preactivation atmosphere.The results show that the preactivated catalyst is beneficial to improve the conversion and selectivity and thus increase the aldehyde yields.However,when the preactivation temperature exceeded 70℃and the preactivation time was 20 min,the aldehyde selectivity would decrease.In addition,preactivation in the syngas atmosphere is conducive to the formation of catalyst active centers.
