【摘要】 研究了双亲水基型阴离子表面活性剂十六烷基二苯醚二磺酸盐(C16-MADS)与季铵盐型阳离子表面活性剂十二烷基二甲基羟乙基氯化铵(K3)的复配性能,结果表明:当溶液中量比值2α[n(K3)/n(C16-MADS+K3)]为0.67时,协同作用(降低表面张力的能力、效率和形成胶束能力)最强.混合胶束和表面混合吸附层中的组成随溶液组成变化不大,均接近等量比.复配体系的胶束聚集数较单一体系均有大幅度的增加.更多还原

【Abstract】 The formulation performance of hexadecylphenoxybenzenedisulfonate salt(C16-MADS,an ionic surfactant with double hydrophilic groups) with dodecyldimethylhydroxyethylammonium chloride(K3,a cationic surfactant of quaternary ammonium type) was researched.The results showed that the synergic effect was the strongest when α2[K3∶(C16-MADS+K3),mol ratio]=0.67 in the solns.The compns.of the mixed micelles and mixed surface adsorption layers did not change importantly with the soln.compn.,both near to equivalent mole fraction.The micelle aggregation number in the compounded systems increased remarkably as compared to the single systems.更多还原
