摘要： 考察了一种磺酸盐双子(Gemini)表面活性剂SGS-12分别与单链阳离子表面活性剂(DTAC和CTAB)、双季铵盐(CD2N-12和CD2N-16)以及多头基季铵盐(CD3N-12)复配体系的油/水界面性能。结果表明,SGS-12与DTAC,CTAB及CD2N-12复配后可产生明显的正协同效应:当SGS-12与DTAC的复配电荷比为3∶5时,界面张力最低可达2.29×10-3 mN/m;当SGS-12与CTAB的复配电荷比为9∶5时,界面张力最低可达1.84×10-3 mN/m;当SGS-12与CD2N-12的复配电荷比为6∶5时,界面张力最低可达4.3×10-3 mN/m。SGS-12与CD2N-16和CD3N-12复配后无正协同效应。

Abstract: The oil/water interfacial properties of binary blended systems of sulfonate Gemini surfactant (SGS-12) with single cationic surfactants (DTAC and CTAB),bis-quaternary ammonium salts (CD2N-12 and CD2N-16),and multiple quaternary ammonium salt (CD3N-12) were investigated.Results showed that the blended systems of SGS-12/DTAC,SGS-12/CTAB and SGS-12/CD2N-12 display synergism in oil/water interface tension reduction effectiveness.When the blending ratio of SGS-12 to DTAC is 3∶5,the interfacial tension between the aqueous system and crude oil can be decreased to 2.29×10-3 mN/m as the minimum.The lowest interfacial tension of the blended system of SGS-12/CTAB can achieve 1.84×10-3 mN/m at a 9∶5 blend ratio.When the blending ratio of SGS-12 to CD2N-12 is 6∶5,the interfacial tension can be reduced to 4.3×10-3 mN/m as the minimum.However,the blended systems of SGS-12/CD2N-16 and SGS-12/CD3N-12 exhibit no obvious synergism.
