【Abstract】 Alkyl polyglucoside sulfosuccinate diammonium(APG-SA) was synthesized by esterification and sulfonation reaction of alkyl polyglycoside(APG) and maleic anhydride with p-toluenesulfonic acid as catalyst and ammonium sulfite as sulfonating agent.The major influential factors of the synthetic process were studied and the surface properties of product were determined.The optimum conditions obtained by single factor experiment and orthogonal experiment were as follows: esterifying temperature was 90℃,sulfonating temperature was 55℃,amount of catalyst was 1.5%(based on the mass of maleic anhydride),n(maleic anhydride)∶n(APG)=1.5∶1.Under above conditions,the content of anion active substance was 49.64%.更多还原
