摘要
系统地研究了四种酰胺基烷基膦酸二钠新型表面活性剂的表面性质(γ,cmc和Г_∞等),结果表明,这类表面活性剂具有较高的表面活性,是一类具有单链型疏水基的表面活性剂。测定了表面活性剂-庚烷-戊醇-水的拟三元微乳液相图,并用ATR-IR研究了该微乳液在碳钢表面的吸附作用,表明该微乳液在碳钢表面形成了致密的吸附膜,此吸附膜的组成类似于微乳液的界面膜的组成。
The surface properties (γ, cmc, Γ_∞, etc.) of disodium acylaminoalkyl phosphonate (OAMEPNa_2, OAMPPNa_2, DAMEPNa_2, DAMPPNa_2) were systematically studied. The results show that these substance belong to a new kind of surfactants which have high surface activity. The pseudoternary phase diagram has been determined for the microemulsion system consisting of DAMEPNa_2-pentanol-heptane-water. The adsorption of this microemulsion on the carbon steel has been studied by ATR-IR. The results indicate that the composition of adsorption film is similar to that of the interface film of the microemulsion.
