摘　　要：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 R12The surface tensions of 3dodecyloxy2 hydroxypropyl trimethyl ammonium Chlorid(R 12 TAC).Sodium dodecyl sulfate(SDS) and R 12 TAC/SDS aqueous solution have been measured,and the effects of the β cyclodextrin(β CD)on the surface activities of these mixed systems have been investigated.The experimental results show that the surface activities of the mixed sarfactants are higher than those of the single one.The addition of β CD can cause the surface activity of the single surfactant decreasing but the result in the surface activities of R 12 NC1/SDS increasing.
