摘要： 通过化学还原法制备了不同Co/P和P/B摩尔比的Co-P-B非晶态催化剂. 采用XRD, ICP-Mass和氮气吸附-脱附等温线对催化剂的性质进行了表征. 在5.0 MPa和120 ℃条件下, 以1-辛烯的氢甲酰化为模型反应, 对Co-P-B催化剂的活性进行了评价, 并与Co-B及Co-P催化剂进行了比较. 结果表明, 非晶态Co-P-B催化剂对1-辛烯氢甲酰化反应具有良好的活性和选择性. 催化剂中P, B和Co的摩尔比、结构及比表面积等性质影响催化剂的活性和选择性, 添加适量的P有助于提高转化率和选择性. 在Co-P-B(Co摩尔分数为85.4%, P摩尔分数为3.3%)催化剂上, 1-辛烯的转化率为97.2%, C9-醛的选择性达到99.5%.

Abstract: Amorphous Co-P-B catalysts with different Co/P and P/B molar ratios were prepared by chemical reduction method. The catalysts were characterized with XRD, ICP-Mass and N2 adsorption-desorption isotherm. The catalysts were evaluated in the hydroformylation of 1-octene under the reaction conditions of 5.0 MPa and 120 ℃. The results showed that amorphous Co-P-B catalysts exhibited relatively high activity and selectivity in the hydroformylation of 1-octene. The molar ratios of Co/P and P/B, amorphous property and surface area affected the activity and selectivity of the Co-P-B catalysts, and the conversion and selectivity were enhanced by adding appropriate amount of P. Over the Co-P-B catalyst(Co 85.4%, P 3.3%, molar fraction), 97.2% conversion of 1-octene and 99.5% selectivity of C9-aldehyde were obtained under the reaction conditions employed in this study.
