Sec butanol is an important chemical raw material and intermediate, which can be used as a raw material for the production of methyl ethyl ketone, spices, dyes, lubricants, flotation agents, as well as solvents, emulsifiers, dye dispersants, dehydrators, paint removers, and industrial detergents. Tengzhou Zhongkepu adopts gas chromatographyQualitative analysis of impurities in industrial sec butanol products was carried out using chromatography, and the target components for gas chromatography analysis were determined. At the same time, R tx-200 capillary chromatography column was used to analyze the purity and impurity content of sec butanol. All impurities were well separated, and the accuracy and repeatability of quantitative analysis were good.
