GBT 14022.2-2009 工業(yè)糠醇試驗(yàn)方法 詳細(xì)信息：

名稱：毛細(xì)管柱

固定液：聚乙二醇

規(guī)格：25m*0.32mm*0.25mm

型號：PEG-20M

應(yīng)用：GBT 14022.2-2009 工業(yè)糠醇試驗(yàn)方法；GBT 14022.2-1992 工業(yè)糠醇試驗(yàn)方法

       糠醇由糠醛經(jīng)催化加氫制得。它是一種在合成樹脂、塑料、涂料和粘合劑等方面廣泛應(yīng)用的有機(jī)化工原料;又是一種性能優(yōu)良的溶劑。隨著工業(yè)生產(chǎn)的發(fā)展,各行業(yè)對糠醇的質(zhì)量及所含雜質(zhì)的限量提出了不同的要求。有關(guān)糠醇質(zhì)量檢驗(yàn),國外報(bào)道的資料可歸納為兩大類,即化學(xué)分析和色譜分析。國內(nèi)目前通用的方法是測定羥基值。由于產(chǎn)品中含羥基的雜質(zhì)如副產(chǎn)四氫糠醇一并計(jì)入糠醇中,使結(jié)果偏高,對于其它雜質(zhì),亦不能給出定量的結(jié)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.
