【摘要】 以顺丁烯二酸二乙酯和丙酮为原料,在催化剂的作用下,在高压釜中反应得到一种重要的农药中间体丙酮基丁二酸酯。试验表明,当温度为150℃左右,反应时间为20h,顺丁烯二酸二乙酯与催化剂的摩尔比为1∶0.05,压力达到0.8MPa时,收率可达91.8%,该产品的含量为95.5%。更多还原

【Abstract】 Acetone and 1,2-ethylenedicarboxylic acid ester were reacted under high pressure and in the present ofcatalyst to yield an important pesticide intermediate, acetonylsuccinic acid ester. At 150oC, a reaction time of 20 h, amolar ratio for 1,2-ethylenedicarboxylic acid ester to catalyst of 1:0.05, and pressure of 0.8 MPa, product yield was91.8% and purity was 95.5%.更多还原
