摘　　要：用流变仪测定了不同烷基链碳原子数(m=6,8,10,12)阴离子双子表面活性剂粘度,优选出GA12-4-12增粘效果较好,并系统研究了各种因素对GA12-4-12溶液粘度的影响。研究表明,随浓度升高,GA12-4-12溶液粘度上升。加入浓度超过0.03%的无机盐(NaCl、AlCl3.6H2O)对GA12-4-12溶液有降粘作用,加入的AlCl3溶液浓度超过一定值时,GA12-4-12溶液的粘度最后趋于稳定,而较高浓度的CaCl2的加入对GA12-4-12溶液有增粘作用,不同价态的无机盐对GA12-4-12溶液粘度的影响原因有待研究。与有机酸盐(水杨酸钠、十二烷基苯磺酸钠)复合而成的GA12-4-12溶液体系具有较好增粘能力。阴离子双子表面活性剂GA12-4-12溶液和十二烷基苯磺酸钠的复合物粘度随温度的变化先升后降。A rheometer was used to test several anionic gemini surfactants of different alkyl lengths,the most satisfied one of the optimal viscosification was GA12-4-12.Moreover,the effect of various factors on the viscosity of GA12-4-12 was studied systematically.The research shows that the viscosity of GA12-4-12 increases with the increase of concentration.The viscosity of GA12-4-12 reduces when concentration of the inorganic salts(NaCl,AlCl3·6H2O)is over 0.03%.The viscosity of GA12-4-12 finally tends to be stable when concentration of solution AlCl3·6H2O is beyond a certain value.But the addition of solution CaCl2 in high concentration increases the viscosity of GA12-4-12.The cause of effect on other inorganic salts in different valences needs to be further studied.The mixture of gemini surfactant and organic salts(sodium salicylate,SDBS) has better viscosification.The viscosity of mixture containing GA12-4-12 and SDBS goes up and then down as the temperature increases.
