固体超强酸对合成辛基多苷的催化作用

The Catalytic Properties of Solid Superacid for the Synthesis of Octyl Polyglycosides

SO2 -4 /ZrO2 固体超强酸用作合成辛基多苷 (OctylPolyglycosides)的催化剂 ,具有活性高、选择性好、易与产品分离、无污染、可重复利用等优点。文中主要讨论SO2 -4 /ZrO2 ,SO2 -4 /ZrO2 MoO3、SO2 -4 /ZrO2 Fe2 O3、以及SO2 -4 /ZrO2 SiO2 固体超强酸在合成辛基多苷反应中的不同催化活性。实验证明 :同一制备条件下的不同催化剂其活性不同 ,且SO2 -4 /ZrO2 的活性、选择性最好 ,可使葡萄糖的转化率高达 96%。

SO 2- 4/ZrO 2 solid superacid for the synthesis of octyl polyglycosides,it has higher activity,selectivity,implution and reusability.The catalytic activity of SO 2- 4/ZrO 2,SO 2- 4/ZrO 2 MoO 3,SO 2- 4/ZrO 2 Fe 2O 3,and SO 2- 4/ZrO 2 SiO 2 were mainly studied in this paper.The experiments showed that the catalytic activity and selectivity of SO 2- 4/ZrO 2 was better than the others under the same prepared condition for the synthesis of octyl polyglycosides.SO 2- 4/ZrO 2 catalyst could make the conversion of glucoside reach 96% in the synthesis of octyl polyglycosides.
