摘　　要：介绍以双丙酮醇为原料 ,经催化加氢合成异己二醇的方法。研究反应温度、反应压力、反应时间、搅拌转速以及催化剂用量等因素对异己二醇合成工艺和产品收率的影响 ,确定了合成异己二醇较好的工艺条件 ,使合成收率达到 90 %以上。此合成产品收率高 ,操作方便 ,易实现工业化生产。A method for the synthesis of hexylene glycol by catalytic hydrogenation from diacetone is presented. The effects of reaction temperature,pressure and time, amount of catalyst and rate of agitation on product yields are discussed.The advanced operating conditions for synthesis of hexylene glycol are obtained. The yield of the synthesis can be higher than 90%. The new process is featured by high yield, easy operation, which is convenient for the realizing commercial production.
