?丙二醇是重要的有機合成原料,目前國內(nèi)均采用環(huán)氧丙烷加壓水合的生產(chǎn)工藝.水合、雙效蒸發(fā)器中的主組分測定的常規(guī)方法是折光法和化學(xué)法,目前主要采用這兩種方法.現(xiàn)用方法的局限在于只能測定丙二醇含量而無法了解其它組分含量.為滿足生產(chǎn)中提高收率、降低單耗的需要,有必要建立一個有效、快速測定丙二醇及其雜質(zhì)含量的分析方法.

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.
