GBT 14022.2-2009 工业糠醇试验方法
GBT 14022.2-2009 工业糠醇试验方法 详细信息：

名称：毛细管柱

固定液：聚乙二醇

规格：25m*0.32mm*0.25mm

型号：PEG-20M

应用：GBT 14022.2-2009 工业糠醇试验方法；GBT 14022.2-1992 工业糠醇试验方法

       糠醇由糠醛经催化加氢制得。它是一种在合成树脂、塑料、涂料和粘合剂等方面广泛应用的有机化工原料;又是一种性能优良的溶剂。随着工业生产的发展,各行业对糠醇的质量及所含杂质的限量提出了不同的要求。有关糠醇质量检验,国外报道的资料可归纳为两大类,即化学分析和色谱分析。国内目前通用的方法是测定羟基值。由于产品中含羟基的杂质如副产四氢糠醇一并计入糠醇中,使结果偏高,对于其它杂质,亦不能给出定量的结果。

GBT 14022.2-2009 Test method for industrial furfuryl alcohol
GBT 14022.2-2009 Test method for industrial furfuryl alcohol Details:

Name: capillary column

Fixative: polyethylene glycol

Specifications: 25m*0.32mm*0.25mm

Model: PEG-20M

Application: GBT 14022.2-2009 Test method for industrial furfuryl alcohol; GBT 14022.2-1992 Test method for industrial furfuryl alcohol

        Furfuryl alcohol is obtained by catalytic hydrogenation of furfural. It is an organic chemical raw material widely used in synthetic resins, plastics, coatings and adhesives; it is also a solvent with excellent performance. With the development of industrial production, various industries have put forward different requirements for the quality of furfuryl alcohol and the limit of impurities contained in it. Regarding the quality inspection of furfuryl alcohol, the data reported abroad can be classified into two categories, namely chemical analysis and chromatographic analysis. The current common method in China is to measure the hydroxyl value. Since the impurities containing hydroxyl groups in the product, such as the by-product tetrahydrofurfuryl alcohol, are included in the furfuryl alcohol, the results are high, and quantitative results cannot be given for other impurities.

        Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. developed the gas chromatography analysis of furfuryl alcohol, and the results were accurate and reliable.
