醋酸仲丁酯加氢制备仲丁醇

摘要

Using alumina as the support,a series of CuO/Al2O3 catalysts was prepared by impregnation method. The influence of reaction conditions of sec-butyl acetate hydrogenation was investigated. The results showed that the conversion of sec-butyl acetate and the selectivity to sec-butyl alcohol, butyl alcohol and alcohol were 98. 16% ,20.48% ,93. 37% and 88. 81% respectively under the optimum reaction condition as follows:reaction temperature 265℃ ,reaction pressure 8.0 MPa,space velocity 0.2 h-1 and n (hydrogen ):n( sec-butyl acetate) = 20.%以氧化铝为载体,采用浸制法制备了一系列负载型CuO/Al2O3催化剂,研究了醋酸仲丁酯加氢反应条件对反应结果的影响.结果表明,在反应温度265℃、反应压力8.0 MPa、空速0.2 h-1和氢酯物质的量比20条件下,醋酸仲丁酯转化率为98.16％,仲丁醇选择性为20.48％,丁醇选择性为93.37％,乙醇选择性为88.81％.
