Abstract

The invention discloses an ethylene glycol bi-sulpho succinic acid bi(2-methyl amyl) artesunate and a production method thereof. The product is prepared by reacting maleic anhydride with 2-methyl-1-amyl alcohol to form a monoesterfication product, reacting the monoesterfication output with sodium sulfite to form a sulphonated product, and then reacting the sulphonated product with ethylene glycol. The product has good performance and is simple to synthesize.

Description

Technical field: [0001] The invention relates to a surfactant and a production method thereof. Background technique: [0002] Existing surfactants have deficiencies in work performance, scope of use, etc., and their production is relatively complicated. Invention content: [0003] The object of the present invention is to provide a kind of good performance, synthetic simple ethylene glycol bis-sulfosuccinic acid bis(2-methylpentyl) ester sodium and production method. [0004] Technical solution of the present invention is: [0005] A kind of di(2-methylpentyl) sodium ethylene glycol bissulfosuccinate, is characterized in that: its chemical structural formula is: [0006] [0007] A kind of production method of di(2-methylpentyl) sodium ethylene glycol bissulfosuccinate, is characterized in that: comprise the following steps successively: [0008] (1) Monoesterification reaction: react maleic anhydride with 2-methyl-1-pentanol to form a monoesterification product, the...
