摘要
采用缩醛法对三乙烯四胺进行脒基化,获得一种二元脒基化合物,与十二烷基苯磺酸钠混合,制得粘弹性流体,考察了CO2、混合液配比、温度对流体粘弹性的影响。结果表明,在35℃下,当二元脒基化合物与十二烷基苯磺酸钠的摩尔比为1∶1.2时,溶液的粘弹性最佳,显示出蠕虫状胶束的特征,混合溶液的网络结构。
Two amidine groups（ N＇-（ 2-{ 2-[2-（ dimethylamino-methyleneamino）-ethylamino]-ethylamino}-ethyl）-N,N-dimethyl formamidine）（ DEADMF） was synthesized through amidazation of triethylenetetramine. A viscoelastic fluid was prepared by mixing DEADMF and conventional anionic surfactant sodium dodecyl benzene sulfonate（ SDBS）. The effects of CO2,mixture liquid,temperature and mole ratio of DEADMF and SDBS on the mixed system were implored. The result showed that the viscoelasticity of the mixed system was optimized when temperature and mole ratio of DEADMF and SDBS were fixed at 35 ℃and 1∶ 1. 2 respectively,the characteristics of wormlike micelles and the network formed in the mixed system was observed.
