阴、阳离子表面活性剂混合体系的增溶作用

Solubilization of Mixed System of Anionic-cationic Surfactant

研究了3-十六烷氧基-2-羟丙基三甲基氯化铵（R16TAC）和十二烷基磷酸钠（AS）混合体系对正戊醇、正己醇、苯甲醇、正辛醇、环乙烷、正己烷、四氯化碳、苯、甲苯、正庚烷和正癸烷的增溶作用.结果表明,混合体系对极性物的增溶均低于两单纯体系,曲线呈“V”型,物质的量比为1:1时增溶量最小.而对非极性物的增溶呈“马鞍”型,量比为1:1时增溶量最大.

The solubilization of n-pentanol, 1-hexanol, benzyl alcohol, 1-octanol, cyclohexane, n-hexane, carbon tetrachloride, benzyl, toluene, n-heptane and n-decane in mixed solution of 3-hexadecanealkoxyl-2-hydroxylpropyl trimethyl ammonium chloride (R16TAC) with sodium dodecyl sulfonate(AS) have been studied. The experimental results show that the solubilizing ability of mixture system is lower for polat substances than that of single surfactant aqueous solution,' V type isotherm curves of solubilized amount of polar solute has been observed,and minimum solubilizde amount is at the molar ratio 1:1 of R16 TAC/AS. However the solubilizing ability of mixture surfactants for non-plar substances is stronger than that of single surfactant solution, the solubilizing isotherm curves present' saddle 'shape, and maximum solubilized amount is at the molar ratio 1:1 of R16TAC/AS.
