Effect of omega-hydrogenation on the absorption of fluorononanols at the hexane/water interface: Miscibility in the adsorbed film of fluorononanols
Article Abstract:
A study to measure the interfacial tension to the hexane solution of 1H,1H-perfluorononanol (FDFC9OH) and its omega-hydrogenated analogue, 1H,1H,9H-perfluorononanol (HDFC9OH) against water as a function of total molality and composition of mixture at 298.15 K under atmospheric pressure is performed. The results indicate that the Gibbs energy of adsorption (G(super H,E)) value is negative in the gaseous state and is positive and increases with decreasing interfacial tension in the condensed state.

Effect of omega-hydrogenation on the adsorption of fluorononanols at the hexane/water interface: Pressure effect on the adsorption of fluorononanols
Article Abstract:
The interfacial tension gamma of the hexane solution of 1H,1H-perfluorononanol (FDFC9OH) and its omega-hydrogenated analogue, 1H,1H,9H-perfluoronanol (HDFC9OH), against water was measured as a function of pressure and concentration at 298.15 K to clarify the effect of omega-dipole on the orientation of fluorononanol molecules. The adsorbed films of both alcohols exhibit two kinds of phase transition among three different states, the gaseous, expanded, and condensed states.

Effect of omega-hydrogenation on the adsorption of fluorononanols at the hexane/water interface: Temperature effect on the adsorption of fluorononanols
Article Abstract:
The effect of omega-dipoles on the adsorbed film of fluoroalkanol at the oil/water interface is clarified. The partial molar entropy and energy changes associated with the adsorption of HDFC9OH are evaluated and compared to those of FDFC0OH in order to see the effect of omega-dipoles on the adsorption of HDFC9OH.
