摘要：

Petroleum sulfonate (PS) was prepared in an autoclave sulfonation reactor using HIV-400 furfural extract oil of Daqing Refinery as feedstock and oleum (120%) as sulfonation agent. The effects of synthesis conditions were studied, and the PS yield was 45.1% with 48.2% of active components under the following best synthesis technology conditions: acid-oil ratio of 0.45:1 and reaction temperature of 60 degrees C. The interfacial tension between crude oil and the water phase was effectively reduced by adding the PS at low dosage, when it was compounded with sodium carbonate, the interfacial tension could be under 10-3 mN/m, meeting the requirements of an oil-displacing surfactant.
