摘　　要：针对传统的非α-生育酚均相催化转型工艺存在的催化剂残留、废液处理难度大等问题,采用两步后合成磺化法制备了嫁接磺酸基团的MCM-41非均相催化剂,并通过XRD、FTIR等方法对其进行了表征。首次将磺酸型MCM-41催化剂用于非α-生育酚的羟甲基化-加氢还原转型反应,得到适宜的转型反应条件为反应温度180℃、反应时间4.5 h、催化剂用量为天然混合生育酚原料的16%,在此条件下α-生育酚收率为77.56%。催化剂复用5次后仍然具有较高的活性,α-生育酚收率为66.27%。For the problems of catalyst residue and ditticult treatment ot waste liquid in tracntlonat nomu- geneous catalytic conversion process of non -α-tocopherol, sulfonic acid group grafted on MCM -41 heterogeneous catalyst was prepared by two step posterior synthesis sulfonation method, and characterized by XRD and FTIR. Sulfonic acid functionalized MCM -41 catalyst was used in hydroxymethylation -hy- drogenation reduction transformation reaction of non - α - tocopherol for the first time, and the suitable transformation reaction conditions were obtained as follows： reaction temperature 180℃, reaction time 4.5 h, dosage of catalyst 16% of the naturally mixed toeopherols. Under these conditions, the yield of α - tocopherol was 77.56%. The catalyst still had high activity when it was reused for five times, and the yield of α - tocopherol was 66.27%,
