棉籽油脚单乙醇酰胺磺基琥珀酸单酯盐的制备
摘要
利用不经提纯的棉籽油脚为原料
合成出棉籽油脚单乙醇胺磺基琥珀酸单酯盐.通过正交实验设计
确定了合成棉籽油脚单乙醇胺的优化条件为:反应温度为80℃
反应时间为3h
W(催化剂)=4.5%
n(RCOOCH3):n(H2NCH2CH2OH)=1∶1.1.界面张力测定结果表明
合成的棉籽油脚单乙醇胺磺基琥珀酸单酯盐能与克拉玛依七东一区原油形成10-3mN/m超低界面张力.
Abstract
The disoium cottonseed wasted-oil monoethanolamine sulfosuccinate was synthesized from natural cottonseed wasted-oil. By orthogonal experiments
The optimized reaction conditions of amidation are reaction temperature 80℃
reaction time 3h
amount of catalyst 4.5%(based on the weight of reations) and n(RCOOCH3):n(H2NCH2CH2OH)=1:1.1. The surface properties were detected and the results showed that the monoethanolamine sulfosuccinate was a good surfactant which can produce ultra-low interfacial tension (10-3 mN/m order) and can be used for ejecting rock-oil.
