酯化工艺水中乙二醇含量分析方法的探究

Determination of Glycol in Esterification Process Water

酯化工艺水中乙二醇含量的高低关系到聚酯生产工艺的稳定性,所以对其分析方法的研究在聚酯生产中有着重要的意义。与传统的滴定(碘量法)相比,气相色谱内标法具有快速、简单、准确等优点,可以缩短分析的时间,减少人为误差,对于聚酯生产在线监控有着积极的作用。

Glycol content in process water affected the stability of polyester production, so gas chromatography internal standard method was applied to determine the glycol in esterification process water. This method had some advantages of rapid, simple and accuracy, and could shorten the analysis times and reduce human error.
