摘要
According to process route and conditions decided by small scale test,disodium alkyl polyoxyethylene(3) ether sulfosuccinate(AEMES) was pilot produced.The optimal process conditions were that esterification temperature 80℃,n(Ether):n(anhydride)=1:1.05,esterification time 6h,catalyst ZY-1,sulfonation temperature 70℃,n(anhydride):n(salt)=1:1.05,and sulfonation time 2h.Technical indexes except sodium sulfite content reached the requirements of light industry standard of Disodium sulfosuccinate(manuscript).The final product without adding hydrogen peroxide,sodium content can be no more than 0.2% of the requests at the conditions of 25℃ for 5 days or 45℃ for 1 day.
