文摘The raw heavy alkylbenzenes were fractionately separated into different fractions, from which five fractions with low, middle and high average molecular weight were collected and sulfonted by ClSO_ 3 H into corresponding heavy alkylbenzene sulfonates(HABS). Their synergetic effects on the interfacial tensions of Sichang(Daqing Oilfield) oil-water have been investigated. The interfacial activity of the mixed HABS of different molecular weight has been remarkably improved in comparison with that of single HABS.
