Cellulose 3,5-dimethylphenylcarbamate was successfully immobilized onto bare silica gel for HPLC through the intermolecular polycondensation of triethoxysilyl groups, which were introduced onto the cellulose derivative via epoxide ring-opening reaction under acidic conditions. The immobilized-type chiral packing material (CPM) exhibited high chiral recognition ability and could be used with various eluents, which are incompatible with the conventional CPMs prepared by coating the derivative onto silica gel.
通过三乙氧基硅烷基的分子间缩聚反应,成功地将3,5-二甲基苯基氨基甲酸纤维素酯固定在用于高效液相色谱(HPLC)的裸硅胶上,其中三乙氧基硅烷基是在酸性条件下通过环氧开环反应引入到纤维素衍生物上的。这种固定化型手性填充材料(CPM)表现出高的手性识别能力,并且可以与各种洗脱剂一起使用,而这些洗脱剂与通过将衍生物涂覆在硅胶上制备的传统CPM不相容。
