季铵盐快速定量分析方法对于季铵盐产品的开发、应用具有重要的意义.应用四苯硼钠返滴定分析方法对季铵盐定量分析进行了研究,探讨了分析结果的重现性和准确性以及NaOH加量对滴定终点的影响,并与沉淀法、HG/T2230-2006十二烷基二甲基氯化铵季铵盐定量分析方法进行了对比.结果表明:该方法适合于季铵盐定量分析,且分析结果重现性好,准确率为99.5%.
The rapid quantitative analysis of quaternary ammonium salt is of great significance to the development and application of quaternary ammonium salt products.Quantitative analysis of quaternary ammonium salts is carried out by using tetraphenylboron sodium back titration method.The repeatability and accuracy of the analytical results are discussed And the amount of NaOH added on the endpoint of the titration were compared with precipitation method, HG / T2230-2006 dodecyl dimethyl ammonium chloride quaternary ammonium quantitative analysis results show that: This method is suitable for quaternary ammonium Salt quantitative analysis, and the analysis of reproducible results, the accuracy rate of 99.5%.
