Abstract:Ethylene glycol Gemini sodium 2-ethyl-1-butanol inate was synthesized by the method of using carbonyl solid acid as the catalyst and anic solvents in esterification and without any extra phase transfer catalysts in sulfonation at normal atmospheric pressure. The optimal synthetic conditions were as follows: in the single-esterification, n(ethylene glycol):n(maleic anhydride)=:2
