摘要
介绍了由二丙酮醇在高压、加热条件下还原合成２－甲基－２，４－戊二醇。影响２－甲基－２，４－戊二醇的收率的因素有：压力、温度、催化剂用量、反应时间及搅拌次数等。通过实验得出如下最佳工艺条件：压力３．０ＭＰａ，温度９５℃～１０５℃，催化剂用量１０％，反应时间７ｈ，搅拌速率５５次／ｍｉｎ。
Reported in this paper is the synthesis of 2-methyl-2,4-pentanediol through reducing diacetone alcohol under the conditions of high pressure and heating. The effects of reaction conditions, such as pressure, temperature, consumption of catalyst, reaction time and agitation speed on the yield of 2-methyl-2,4-pentanediol have been studied, and the results show that the optimum technology parameters are pressure 3.0 MPa, temperature 95℃￣105℃, consumption of catalyst 10%, reaction time 7 h and agitation speed 55 times/min.
