在较低压力(0.5—1.5MPa)下,以12-钨磷酸为催化剂,研究了丁烯-1与乙酸的气—液加成酯化反应。在适当反应条件下乙酸转化率可达86mol%。对催化剂浓度、反应温度、丁烯-1压力、乙酸中含水量以及反应时间诸因素进行了较为详细的考察。
Gas-liquid addition esterification of butene-1 with acetic acid was studied at lower pressures (0.5-1.5 MPa) using 12-tungstophosphoric acid as catalyst. Under the appropriate reaction conditions, the conversion of acetic acid can reach 86mol%. The factors such as catalyst concentration, reaction temperature, butene-1 pressure, water content in acetic acid and reaction time were investigated in detail.
