摘要
研究了用石油馏分液相氧化产物制得的石油羧酸盐与不同磺酸盐 (ORS 41、B 10 0、MS 45等 )的复配体系的界面活性。结果表明 ,复配体系的界面活性优于单一的石油羧酸盐或磺酸盐体系。将少量磺酸盐与石油羧酸盐复配 ,可使体系达到超低界面张力所需的矿化度大大降低 ,碱度范围大为拓宽 ,达到超低界面张力值所需的时间大为缩短 ,初始界面张力很低。
The interfacial activities of petroleum carboxylate produced by liquid phase oxidized hydrocarbon and its combined systems with sulfonate have been studied. The research results have shown that the interfacial activities of combined systems are much better than that of pertoleum carboxylate or sulfonate systems alone. Adding a little sulfonate to pertroleum carboxylate can substatially decrease the concentration of electrolyte necessary to obtain ultralow interfacial tension(IFT). The time needed to arrive at low IFT is very short for the combined systems. The initial low IFT is very advantageous to enhance oil recoveries. In general, petroleum carboxylate shows good synergism with several sulfonates. (ORS 41, B 100, MS 45, etc).
