摘　　要：以富含正丁烯的催化液化气和冰醋酸为原料,采用优化改良后的大孔强酸性阳离子交换树脂催化剂合成醋酸仲丁酯。测试其最佳反应条件,结果显示在反应温度105℃,反应压力1.0 MPa,醋酸与丁烯摩尔比2.0,进料质量空速3.0 h-1的工艺条件下,丁烯转化率≥58%,醋酸仲丁酯选择性≥92%。The rich in n-butene catalytic LPG and acetic acid as raw materials, the improved optimization macroporous strong acid cation exchange resin as catalyst, to synthesize sec-butyl acetate. The optimal reaction conditions for the test results show that the reaction temperature is 105 ℃, reaction pressure is 1.0 MPa, acetic acid and butene molar ratio is 2.0. Under the conditions of feed WHSV 3.0 h^（-1）, the butene conversion rate≥58 %, the butyl acetate selectivity ≥92 %.
