Abstract

The invention discloses a fatty alcohol polyvinyl ether (9) octyl sulfo succinic mixed diester sodium and relative preparation, comprising that processing monoester reaction between maleic anhydride and fatty alcohol polyvinyl ether (9), and processing diester reaction between the reaction product of monoester reaction and octanol, and processing conjugate addition reaction between the reaction product of diester reaction and sodium bisulfite to obtain final product. The invention has high-quality property and simple process.

Description

Technical field: [0001] The present invention relates to a surfactant. Background technique: [0002] The existing succinic acid diester sulfonate series surfactants are generally esterified with excess alcohol, and then the esterified product is neutralized and washed with water, dehydrated and deacidified, and then a sulfonated phase transfer catalyst is added. closed system. The process is complicated, and the product performance is not very satisfactory. Invention content: [0003] The object of the present invention is to provide a fatty alcohol polyoxyethylene ether (9) octyl sulfosuccinic acid mixed diester sodium with good performance and simple synthesis method and a preparation method. [0004] Technical solution of the present invention is: [0005] A kind of fatty alcohol polyoxyethylene ether (9) octyl sulfosuccinic acid mixed diester sodium, is characterized in that: structural formula is: [0006] [0007] A kind of preparation method of fatty alcohol...
