摘要
将阴离子表面活性剂窄馏分重烷基苯磺酸盐(HABS 3#)与不同类型的表面活性剂复配,并测定复配体系对十二烷/水溶液的界面张力。结果表明,阴离子HABS 3#与非离子脂肪醇聚氧乙烯醚(AEO-9)、两性离子椰油酰胺甜菜碱(CAB-35)、阴离子窄馏分重烷基苯磺酸盐(HABS 1#)复配后,均能在总浓度为0.01%时,在一定的复配比例下,使得油水界面张力降至超低(10^(-3)mN/m),而与阳离子十六烷基三甲基溴化铵(CTAB)复配后,体系对油水界面张力反而升高。获得最低油水界面张力时的复配比例分别为AEO-9含量15%,CAB-35含量40%,HABS 1#含量10%,CTAB含量0。
Through the interfacial tension( IFT) measurements on the mixed system of heavy alkyl-benzene sulfonate( HABS 3#) with different types of surfactants,when HABS 3#mixed with nonionic primary alcohol ethoxylate( AEO-9),zwitterionic cocamidopropyl betaine( CAB-35) and HABS 1 #,with a total concentration of 0. 01%,the systems obtain the ultra-low IFT around 10^(-3) mN/m between the dodecane and water at a specific mixed proportion. However the compound system of HABS 3 # with cationic cetyl trimethyl ammonium bromide( CTAB) obtain a higher IFT. The mixed proportion is 15% of AEO-9,40% of CAB-35,10% of HABS 1# and 0 of CTAB respectively when the IFT appears the lowest.
