Pentaerythritol products with a purity of 91.88% and a whiteness of 97.5% have the problems of yellow color and low purity. Carry out research on the analysis of impurities in the product and decolorization and impurity removal technology, in order to provide effective decolorization and impurity removal technology and product quality control for product production. parameter. Through the detection and analysis of infrared, nuclear magnetic, Raman, TG, DSC, LC-MS and other instruments, it is confirmed that the main impurities in the product are dipentaerythritol, a small amount of polypentaerythritol, pentaerythritol methanol ether, a trace amount of acetal and ester compounds, of which yellow impurities The ingredients may be acetals and esters. Through the study of pentaerythritol synthesis conditions and post-treatment process, it is preliminarily verified that the yellow impurities are acetal and ester compounds.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. developed a packed column for the determination of pentaerythritol, with high column efficiency, good separation, and satisfactory results.
