正/负离子双子表面活性剂复配体系的油/水界面性能研究
|
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2.29×10-3m N/m;当SGS-12与CTAB的复配电荷比为9∶5时,界面张力最低可达1.84×10-3m N/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4.3×10-3m N/m。SGS-12与CD2N-16和CD3N-12复配后无正协同效应。
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- 3m N / m as the minimum.The lowest interfacial tension of the blended system of SGS- 12 / CTAB can achieve 1. 84 × 10- 3m N / m at a9∶ 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- 3m N / m as the minimum. However,the blended systems of SGS- 12 / CD2N- 16 and SGS- 12 / CD3N- 12 exhibit no obvious synergism.
