摘　　要：【目的】研究快速直接测定未经衍生化处理甘油氢解产物（1，3-丙二醇；l，2-丙二醇）的方法。【方法】以甲醇为溶剂，醋酸正丁酯为内标物建立气相色谱分析测试方法，并采用ZB-5HT气相色谱柱。【结果】当样品组成浓度在0～27mg·mL^1范围内，内标法校正实验工作曲线的线性相关系数R达到0．9993～0．9995，标准残差（SE）为0．0040~0．0112。对6个实验真实样品进行平行定量测定，结果表明最大相对偏差为0．06～0．09，平均回收率为99．19％～l00．42％。【结论】该方法可以满足直接测定甘油氢解液相产物的要求。【Objective】This study focused on directly and rapidly quantitative analysis of liquid products of glycerol hydrogenolysis to propanediols(1,3-PDO;1,2-PDO)without derivatization by using gas chromatography.【Methodes】The test method of gas chromatography direct analysis was established by using the ZB-5HT column in gas chromatography,methanol as solvent,and n-butyl acetate as the internal standard.【Results】Experimental results showed that linear correlation coefficients(R)were 0.9993~0.9995 with the components concentration in the range of 0~27mg·mL-1,and the standard errors(SE)were 0.0040~0.0112.Parallel determination experiments were carried in six real products of hydrogenation,and the maximum relative deviation(MRD)was in the range of 0.06~0.09.【Conclusion】The average recovery rate was 99.19%~100.42%,which could meet the requirements of analyzing the liquid products of glycerol hydrogenation.
