AbstractThe height of liquid rise in Pyrex glass capillaries at microemulsion/oil and microemulsion/brine interfaces was measured for the toluene-brine-sodium dodecyl sulfate-butanol system, as a function of brine salinity. Results show that, in the two phase regions, σog > σμg at lower salinities and σμg > σwg at higher salinities, where σog, σμg, σwg are the interfacial tensions between glass and the oil, microemulsion, and brine phases, respectively, these differences increasing with distance from the three-phase region. In the three-phase region, σμg > σwg > σog for freshly etched glass, and σwg > σμg > σog for untreated glass surfaces, the differences being small. Values of cos θc (θc = contact angle) were estimated using the interfacial tension data of A. Pouchelon (thesis, Universite Pierre et Marie Curie, Paris, 1983; and with J. Meunier, D. Langevin, D. Chatenay, and A. M. Cazabat, Chem. Phys. Lett. 76, 277, 1980). © 1984.
