新型均三嗪类CO_(2)开关型表面活性剂的合成及性能评价

Synthesis and performance evaluation of a novel s-triazine CO_(2)switchable surfactant

本文以三聚氯氰、十二胺、丙烯酸甲酯、乙二胺和3-二甲胺基丙胺为主要原料,依次通过加成反应、亲核取代反应和中和反应,制得一种含叔胺基的均三嗪类羧酸盐CO_(2)开关型表面活性剂,通过红外光谱对产物进行了结构表征,并对产物的表/界面活性、CO_(2)/N2开关响应性能进行了评价,探索了上述叔胺基CO_(2)开关型羧酸盐表面活性剂在三次采油领域的潜在应用价值。

In this paper,raw materials such as cyanuric chloride,dodecylamine,methyl acrylate,ethylenediamine and 3-dimethylaminopropylamine were used to create a triazine carboxylate CO_(2)switchable surfactant containing a tertiary amine group via addition,nucleophilic substitution,and neutralization reactions.FT-IR was used to analyze the product′s structure,and the surface/interface activity was also investigated.The emulsification and CO_(2)/N2 switchable performance of the aforesaid tertiary amine CO_(2)switchable carboxylate surfactants were examined,and the prospective application value in the field of tertiary oil recovery was investigated.
