摘　　要：研究了碎米葡萄糖制备山梨醇的氢化工艺。通过单因素和正交试验,获取最佳氢化工艺条件为:反应压力10MPa,反应温度120℃,pH=8,催化剂用量5%,转速200r/min,时间2h。在此条件下,碎米葡萄糖转化为山梨醇的转化率为40.34%。Sorbitol was prepared by hydrogenation of broken-rice glucose and the optimal hydrogenation conditions were obtained by single factor tests and orthogonal test： pressure 10 MPa, temperature 120 ℃, pH 8, the dosage of catalyst 5%, shaking speed 200 r/min, and reaction time 2 h. Under these conditions, the ratio of broken-rice glucose to sorbitol reached 40.34%.
