丙二醇是重要的有机合成原料,目前国内均采用环氧丙烷加压水合的生产工艺.水合、双效蒸发器中的主组分测定的常规方法是折光法和化学法,目前主要采用这两种方法.现用方法的局限在于只能测定丙二醇含量而无法了解其它组分含量.为满足生产中提高收率、降低单耗的需要,有必要建立一个有效、快速测定丙二醇及其杂质含量的分析方法.
浩瀚色谱（山东）应用技术开发有限公司，研制生产的《聚乙二醇-20M填充色谱柱测定丙二醇》柱效高，分离好，取得了不错的效果。

Propylene glycol is an important organic synthetic raw material, and currently the production process of epoxy propane pressurized hydration is adopted in China The conventional methods for determining the main components in hydration and double effect evaporators are refractive index method and chemical method, which are currently mainly used The limitation of the current method is that it can only determine the content of propylene glycol and cannot understand the content of other components To meet the needs of improving yield and reducing unit consumption in production, it is necessary to establish an effective and rapid analytical method for determining the content of propylene glycol and its impurities
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has developed and produced the "Polyethylene Glycol-20M Filled Chromatography Column for Determination of Propylene Glycol", which has high column efficiency, good separation, and achieved good results.
