HH-FFAP毛细管柱测定丙二醇产品及其杂质

   丙二醇是重要的有机会成原料，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。

    滕州市浩瀚色谱仪器技术服务有限公司，《HH-FFAP毛细管柱测定丙二醇产品及其杂质》建立了弹性石英毛细管柱气相色谱分析工业1,2-丙二醇含量的方法。通过不同类型检测器、不同固定相和不同色谱操作条件的对比试验,对方法的准确性及影响因素进行了研究,并对样品馏程与1,2-丙二醇含量的关系进行了探讨。该方法操作简便、快速、准确,相对误差小于1%,用于样品分析取得了满意的结果,并在生产装置的节能降耗以及安全生产等方面起到了积极作用。

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.
