摘要：The composition of heavy alkyl benzene sulfonates (HABS) was determined and the HABS was separated by a preparative HPLC. The surface and interfacial tensions of the components were measured. The results show that the HABS is a mixture of homologues, C(n)ABS, with different alkyl carbon numbers ranging from 12 to 25 on phenyl group. The CMC of six components, C(12)ABS, C(13)ABS, C(16)ABS, C(17)ABS, C(18)ABS, and C(19)ABS are 0.401-0.030 g.L-1. The C(16)ABS has the strongest interfacial activities. There occurred synergism between C(16)ABS and ionized organic acids in the crude oil produced by Na2CO3.
