Abstract

The temperature effect on the adsorption of fluorooctanols at the hexane/water interface was discussed. The interfacial tensions of the hexane solution of fluorooctanols(1,1,2,2-tetrahydrotridecafluorooctanol, TFC₈OH, and 1,1-dihydropentadecaflurooctanol, DFC₈OH) against water were measured as a function of temperature and molality under atmospheric pressure. By drawing the interfacial pressure π vs mean area per adsorbed molecule A curves, it was concluded that the adsorbed film of TFC₈OH exhibits a first-order phase transition between the gaseous and expanded states.
