摘　　要：在异己二醇中试试验中,采用均匀设计安排中试试验,验证放大准则,确定放大参数,考查了反应温度、反应压力、催化剂用量等工艺条件的操作稳定性,取得了较好的试验结果,使异己二醇的生产收率可以稳定在90%以上。这证明高压催化加氢合成异己二醇工艺可行,其适宜的工艺条件反应温度为130℃,压力1.5MPa,搅拌转速410r/min,催化剂用量3%。The uniform design was used as an experimental method to test and verify amplifying standard and define amplifying parameter, and exame stability of reacting temperature, reacting pressure and amount of catalyst, etc. Advanced test results were obtained. The yield of the synthesis can reach as high as above 90%, indicating that the process for the preparation of hexylene glycol by highpressure catalytical hydrogenation was feasible. The suitable technological condition were as follows, reacting temperature 130℃, pressure 1.5 MPa, stirring rotation speed 410 r/min, amount of catayst 3%.
