YUAN Hao1,ZHANG Wei1,ZHENG Hai-wu2(1.Guizhou Research Institute of Chemical Industry,Guiyang 550002,China;2.Research Institute of Science Technology,Yanshan University,Qinhuangdao 066004,China)  
In the presence of catalyst,ammonium sulfate of alkylpolyglycoside was synthesized with alkylpolyglycoside and amidosulphonic acid as materials.The effects of reaction type and dosage of catalyst,feed ratio,temperature and so on were investigated.The optimized process conditions are as follows:n(APG):n(amidosulphonic acid)=1:1.15,the dosage of catalyst CAT is 3% by weight of the reactant,the reaction temperature is 110℃,the reaction time is 3h,the content of anion active substance was 88.9%.
