摘要
针对用大庆原油馏分油制备驱油剂石油羧酸盐时，反应器易结焦的问题，采用了１０＃白油为原料制备驱油剂在氧化反应时不结焦，经汽相氧化皂化和盐度调节，可制备出和大庆原油产生超低界面张力的表面活性剂，其中最低值可达１０－３数量级。
In concerning with the probolem of easy coke deposit inside the reactor during the preparation of petroleum carboxylate for enhanced oil recovery (EOR) by oxidation of fraction of Daqing crude oil,10# white oil is taken as the feed for the feed for the oxidation,and no coke deposide insids the reactor with the feed. A surfactant of petroleum carboxylate can be made from the feed by gaseous phase oxidation, saponification,and adjustment of salinity.With Daqing crude oil,the surfactant shows super-low interfacical tension, which is low to the scale of 10^-3.
