| 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;1,2-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0~27 mg·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%~100.42%。[结论]该方法可以满足直接测定甘油氢解液相产物的要求。 |

| Abstract: |
| [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 0~27 mg·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. |
