【摘要】 采用气相色谱方法分析了甘油与盐酸反应过程中的主要物质。使用KB-WAX毛细管柱及FID检测器,以乙二醇作内标和甲醇定容,并用内标法计算。结果表明,在程序升温下,气相色谱内标法能使GLY,DCP,CPD等几种物质达到基线分离,该方法能满足测试要求。更多还原

【Abstract】 In this paper,a simple gas chromatographic method for the identification of glycerol(GLY),1,3-dichloropropanol-2-propanol,(DCP) and 3-chloro-1,2-propandiol(CPD) in GLY chlorination reaction is described.The results are detected by KB-WAX capillary column with a flame ionization detector(FID) and calculated by an internal stand method.Glycol is used as an internal standard,and the samples are diluted with methanol.This method is simple,rapid and the results are reliable.更多还原
