| 摘 要： | 采用HP-INNOWax(30m×0.32mm,0.5μm)毛细管柱,建立气相色谱-氢火焰离子化检测器(GC-FID)外标法,同时测定由生物柴油副产物甘油制备环氧氯丙烷反应体系中环氧氯丙烷、1,3-二氯丙醇和2,3-二氯丙醇的含量。通过对环氧氯丙烷、1,3-二氯丙醇和2,3-二氯丙醇的线性关系、精密度和回收率试验,获得了满意的结果。线性相关系数分别为环氧氯丙烷0.9999、1,3-二氯丙醇0.9999、2,3-二氯丙醇0.9999;平均回收率:环氧氯丙烷99.86%、1,3-二氯丙醇98.24%、2,3-二氯丙醇102.26%。方法简便、快速、准确率高、重现性好。

| Abstract: | A gas chromatography and external standard methods was developed for detecting simultaneously epichlorohydrin and its intermediates such as 1,3-dichloro-2-propanol and 2,3-dichloro-1-propanol. Samples in the reaction system were detected by GC-FID with HP-INNOWAX(30 m×0.32 mm,0.5 μm) capillary column. The results showed that the linear correlation coefficients for epichlorohydrin,1,3-dichloro-2-propanol and 2,3-dichloro-1-propanol were 0.999 9,0.999 9 and 0.999 9. Recoveries for epichlorohydrin,1,3-dichloro-2-propanol and 2,3-dichloro-1-propanol were 99.86%,98.24% and 102.26%,respectively. The experimental results showed that this method was effective,quick,accurate and stable. |
