【摘要】 用薄层色谱扫描法测定Cl~-和Br~-在亲核取代竞争反应中所生成的相应卤代物混合物各组分摩尔含量,以确定其亲核性强弱.此法操作简便,快速,重现性好,准确度高,可一次同时测定多个样品.更多还原

【Abstract】 in this paper. RC1 and RBr components in the mixture, producing in necleophilic substitution reaction competing necleophiles Cl- and Br-. is determined by TLC. The simplicity, rapidity, repeatability and high accuracy of determination are the advantages of the method, and several samples are determined at the same time.更多还原
