本文考察了盐酸-异丙醇法定量测定双长链烷基甲基叔胺的可靠性，研究了双长链烷基甜菜碱的合成中，产物中未反应的原料叔胺含量的分析测定，进而得出反应的转化率，总结了原料叔胺中含有ECHS和水时对滴定终点产生的影响。
We evaluated the reliability of qualitative measurement of N-methyl, N, N-dialkyl tertiary amine with long alkyl chains using HCl-isopropanol method, and applied this to quantify the content of the leftover tertiary amine reactant in the synthesis of a long chain dialkylated carboxybetaine, in order to estimate the conversion rate of the reaction. We also highlighted the effects of the ECHS content in the tertiary amine and the presence of water on the determination of the end point in titration. |
