| 摘 要： | 对脂肪醇聚氧乙烯(3)醚(AEO3)进行糖苷化,用反相高效液相色谱法对糖苷化后的混合物进行了检测分析。确定了色谱条件:C18Diamonsil,5μm,4.6×250mm色谱柱,乙氰∶N,N 二甲基甲酰胺=1∶4(体积比)为流动相,示差折光检测器。结合用化学法测得的未反应葡萄糖、生成的二糖多糖的质量百分含量,可计算出AEO3糖苷化后混合物中的糖苷化物的质量百分含量。该方法的相对标准偏差小于5%。

| Abstract: | The glucosidation of aliphatic alcohol (3) ethoxylates(AEO_3) was made and the production mixture was analysed by reverse phase-high performance liquid chromatograph(RP-HPLC). A good condition for RP-HPLC was established: C_(18)Diamonsil, 5 μm,4.6×250 mm chromatographic column,acetonitrile∶N,N-dimethyl formamide=1∶4(volume ratio)as the mobile phase and a differential refractive index detector.The mass ratio of glucosides was figured out with the unreact ratio of glucose and polysaccharides detected by chemical method. The CV is less than 5%. |
