甲壳素与苯基异氰酸酯衍生物(2a-2d)经氨基甲酰化反应合成了4个新型的甲壳素苯基氨基甲酸酯衍生物(3a-3d),其结构经IR和元素分析表征。分别将3a-3c涂敷于大孔氨丙基硅胶表面(涂覆量均为16 wt%)制得相应的手性固定相(3a'-3c')。3a'-3c'对19个手性化合物的分离性能和耐用性能研究结果表明:3a'-3c'的手性识别性能及耐用性均优于纤维素-三(3,5-二甲基苯基氨基甲酸脂)固定相。
Four novel chitin derivatives (3a - 3d) were prepared by carbamoylation reaction of chitin with phenyl isocyanates. The structures were characterized by IR and elemental analysis. Three ehiral stationa- ry phases(3a' -3c') were obtained by coating 16 wt% 3a -3e on maeroporous silanized silica gel. The enantioseparation capabilities and durability of 3a' - 3c' were investigated by analysis on nineteen ehiral compounds. The results showed that ehiral recognition capability and high durability of3a' -3e' were better than the chiral stationary phase prepared from celhdose tris(3,5-dimethylphenylcarbamate).
