| Abstract: |
| Taking the fuming sulfuric as sulfonating agent to synthesize the petroleum sulfonate, the influences of material, temperature and time on product performance were studied. The optimized materials, technology condition were screened out. The results show that petroleum sulfonate with fine performance can be obtained when rection temperature is 400 and reao tion time is 60 minutes. Lower surface tension and lower interface tension can be obtained in purified petroleum sulfonate which was synthesized by ocean vacuum gas oil and Liaohe vacuum cut 4 fraction oil. |
| Key words: petroleum sulfonate synthesis surface tension interface tension performance assessment |
