微晶纤维素与异氰酸苯酯在4-N,N-二甲基氨基吡啶催化下反应合成三苯基氨基甲酸纤维素酯,反应温度低,反应时间短;以平均粒径6μm、平均孔径15nm、比表面积67m2/g的堆积硅珠做担体,涂敷15%(质量分数)三苯基氨基甲酸纤维素酯在上述担体上制备手性固定相;以此手性固定相高效液相色谱法直接分离(±)-2,2,2-三氟-1-(9-蒽基)乙醇对映异构体,确定了对映异构体的出峰顺序.
Microcrystalline cellulose and phenyl isocyanate in 4-N, N- dimethylaminopyridine catalytic synthesis of triphenylcarbamate cellulose ester, the reaction temperature is low, the reaction time is short; with an average particle size of 6μm, the average A diameter of 15nm, a specific surface area of 67m2 / g deposited silica beads as a carrier, coated with 15% (mass fraction) of triphenylcarbamate prepared in the above-described carrier chiral stationary phase; the chiral stationary phase high performance liquid phase Direct separation of (±) -2,2,2-trifluoro-1- (9-anthryl) ethanol enantiomers by chromatography gave the order of peaks of the enantiomers.
