HH-FFAP毛細管柱測定丙二醇產(chǎn)品及其雜質(zhì)

   丙二醇是重要的有機會成原料，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法，目前主要采用這兩種方法?，F(xiàn)用方法的局限在于只能測定丙二醇含量而無法了解。

    滕州市浩瀚色譜儀器技術服務有限公司，《HH-FFAP毛細管柱測定丙二醇產(chǎn)品及其雜質(zhì)》建立了彈性石英毛細管柱氣相色譜分析工業(yè)1,2-丙二醇含量的方法。通過不同類型檢測器、不同固定相和不同色譜操作條件的對比試驗,對方法的準確性及影響因素進行了研究,并對樣品餾程與1,2-丙二醇含量的關系進行了探討。該方法操作簡便、快速、準確,相對誤差小于1%,用于樣品分析取得了滿意的結果,并在生產(chǎn)裝置的節(jié)能降耗以及安全生產(chǎn)等方面起到了積極作用。

Determination of Propylene Glycol Product and Its Impurities by HH-FFAP Capillary Column

   Propylene glycol is an important opportunity to become raw materials, the current domestic use of propylene oxide pressurized hydration production process. Hydration, double-effect evaporator in the determination of the main components of the conventional method of refraction and chemical method, the main use of these two methods. The limitation of the current method is that the propylene glycol content can only be determined and can not be understood.

    Tengzhou City, the vast chromatographic equipment Technology Co., Ltd., "HH-FFAP capillary column determination of propylene glycol products and impurities" to establish a flexible quartz capillary column gas chromatography analysis of industrial 1,2-propylene glycol content method. The accuracy of the method and the influencing factors were studied by comparing the different types of detectors, different stationary phases and different chromatographic operating conditions. The relationship between the distillation range and 1,2 - propanediol content was also discussed. The method is simple, rapid and accurate. The relative error is less than 1%, which is satisfactory for the sample analysis and has played a positive role in the energy saving and safe production of the production plant.
