        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.
