摘　　要：非水滴定法可定量测定季铵盐N2 6 3浓度 ,预处理对测定结果有显著影响。适当量的碱可以将叔胺盐转化成游离胺 ,但过多的碱会产生较多的季铵碱 ,使测定结果偏低。预处理使N2 6 3中含有一定水 ,如果分析季铵盐纯度 。Titration in non aqueous solution can be used for the quantitative analysis of quaternary ammonium salt N 263 ,but the pretreatment has marked influence on the result of determination Proper quantity of alkali can transform the halide salt of tertiary amine to free amine,but excessive alkali will produce more quaternary ammonium hydroxide,which decreases the value of determination An amount of water will be carried in the sample whilc pretreatment,so it's necessary to remove the attached water in cass of analyzing the product purity
