测定了 3-十二烷氧基 - 2 -羟丙基三甲基氯化铵 (R12 TAC)与十二烷基硫酸钠 (SDS)复配体系的表面活性以及β-环糊精 (β- CD)对二者和 R12 TAC/SDS混合体系表面张力的影响 .结果表明 :R12 TAC/SDS复配件系的表面活性远高于两单纯体系 .β- CD使单一表面活性剂的表面活性降低 ,而使 R12 TAC/SDS复配体系的表面活性升高
The surface activities of 3-dodecyloxy-2-hydroxypropyltrimonium chloride (R12 TAC) and sodium dodecyl sulfate (SDS) CD) on the surface tension of the mixed system with R12 TAC / SDS.The results showed that the surface activity of R12 TAC / SDS complex was much higher than that of two pure systems.β-CD reduced the surface activity of single surfactant, R12 TAC / SDS complex system to increase the surface activity
