摘要
合成了一种耐温抗盐表面活性剂，通过红外光谱分析了该表面活性剂的结构。将其与2500万分子量聚丙烯酰胺进行复配，考察了复配体系的表面、界面性能。研究结果表明：所合成的产物为目标产物；磺基甜菜碱表面活性剂的临界胶束浓度（cmc）为2．19×10^-3mol／L，临界胶束浓度下的表面张力（γcmc）为25．51mN／m；加入聚合物后临界胶束浓度变为4．09×10^-3mol／L，γcmc变为26．65mN／m；表面活性剂质量浓度在0．8—1．5g/L，可使胜利原油油水间的界面张力达到超低数量级（10^-3mN／m）；聚合物的加入有利于乳状液的形成。
A heat resisting and salt tolerant surfactant is synthesized, and the structure is analyzed by Infrared （IR）. The sulfobe- taine surfactant is compounded with 25 million molecular weight of polymer, the surface and interfacial properties of the compound sys- tem are investigated. The experimental resuhs indicate that the product is the target one, the critical micelle concentration of sulfobe- taine surfactant is 2. 19 × 10-3 tool/L, the surface tension （γcmc） is 25.51 mN/m; with the polymer added, the cmc become 4. 09 ×10-3 mol/L, and the Tome become 26. 65 mN/m; the mass concentration of surfactant is in the range of 0. 8 g/L to 1.5 g/L, the water/crude oil interfacial tension is arrived ultra low value 10-3 mN/m from Shengli oilfield. It is conductive to form the emulsion due to the poly- mer added.
