季戊四醇的测定10%OV-101/Chromosorb GAW DMCS填充柱

季戊四醇的测定10%OV-101/Chromosorb GAW DMCS填充柱 详细信息:


名称:填充柱
固定液:10%OV-101
载体:Chromosorb GAW DMCS,180um-250um
规格:2m*3mm
型号:10%OV-101/Chromosorb GAW DMCS
应用:GBT 7815-2008 工业用季戊四醇


纯度91.88%、白度97.5%的季戊四醇产品存在颜色发黄、纯度不高的问题,开展产品中杂质成分分析与脱色除杂技术研究,以期对产品生产提供有效的脱色除杂技术与产品质量控制参数。通过红外、核磁、拉曼、TG、DSC、液质联用等仪器检测分析,确认产品中主要杂质为双季戊四醇、少量多季戊四醇、季戊四醇甲醇醚、微量的缩醛和酯类化合物,其中黄色杂质成分可能为缩醛和酯类化合物。通过季戊四醇合成条件与后处理工艺的研究,初步验证了黄色杂质为缩醛和酯类化合物。

Determination of Pentaerythritol 10%OV-101/Chromosorb GAW DMCS Packed Column


Determination of Pentaerythritol 10% OV-101/Chromosorb GAW DMCS Packed Column Details:



Name: Packed Column

Fixative: 10%OV-101

Carrier: Chromosorb GAW DMCS, 180um-250um

Specifications: 2m*3mm

Model: 10%OV-101/Chromosorb GAW DMCS

Application: GBT 7815-2008 Industrial Pentaerythritol


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.
