Abstract

The invention relates to a quality inspection method for a glycoside sulfonyl succinate product by using the content of maleic anhydride and a sulfonating rate as indexes. The quality inspection method is characterized in that the content of maleic anhydride is detected by a high performance liquid chromatography method, and the sulfonating rate is detected by a nuclear magnetic resonance spectroscopy method; the content of maleic anhydride in a glycoside maleate intermediate and the sulfonating rate of the intermediate are detected, so as to comprehensively inspect the quality of the product.The quality inspection method has the advantages that the residue amount of maleic anhydride in the glycoside maleate system is detected by the high performance liquid chromatography method to detectthe quality of the intermediate, and the sulfonating rate of the glycoside maleate is detected by the nuclear magnetic resonance spectroscopy method to further inspect the quality of the product; theinspection detection result method is scientific, objective and accurate.

Description

technical field [0001] The invention belongs to the technical field of quality inspection of fine chemical products, and in particular relates to a quality inspection method for glycoside sulfosuccinate salt products based on maleic anhydride content and sulfonation rate. Background technique [0002] Glycoside surfactants use natural fatty alcohols and glucose derived from biomass resources as basic raw materials, and are typical representatives of green and safe surfactants. With the concept of green life deeply rooted in the hearts of the people, the green and safety advantages of such products have been widely recognized Therefore, in recent years, the domestic production scale and application fields of glycoside surfactants and their derivatives such as glycoside citrate salt and glycoside sulfosuccinate salt have been rapidly growing and expanding. [0003] The quality indicators of glycoside sulfosuccinate salt products include many aspects, such as solid content, sta...
