聚氧丙烯脂肪酸乙醇酰胺磺基琥珀酸单酯二钠的表面活性

SURFACE ACTICE PROPERTIES OF DISODIUM POLYOXYPROPYLENE FATTY ACID ETHANOLAMIDE SULFOSUCCINATES

合成了一系列聚氧丙烯脂肪酸乙醇酰胺磺基琥珀酸单酯二钠并研究了其表面活性。结果表明 ,随氧丙烯聚合数或脂肪酸碳原子数的增加 ,临界胶束浓度减小而最小表面张力增大 ,润湿力和起泡力都下降 。

Disodium polyoxypropylene fatty acid ethanolamide sulfosuccinates were synthesized and some of their surface active properties were investigated. It had been found that with the increase in the polymerization number of propylene oxide or in the number of carbon atoms of the fatty acid molecular, the critical micelle concentration decreased and the critical surface tension increased, the wetting power and the foaming ability reduced. The foam stability was high and its change was less remarkable.
