Pressure effect on the phase transition in the adsorbed film of alkanol and fluoroalkanol mixture

Article Abstract:

The phase transition of the adsorbed film of 1-icosanol and 1,1,2,2-tetrahydroheptadecafluorodecanol mixture at the hexane/water interface was investigated by interfacial tension measurement at concentration of X2 = 0.280 and 298.15 K. The experimental results were also analyzed thermodynamically. Results showed the the adsorbed film displayed three kinds of first-order transitions. Moreover, the difference in the transition pressure between the two kinds of condensed states can be explained by their molar volume change.

Miscibility in the adsorbed film of an alkanol and fluoroalkanol mixture

Article Abstract:

A study was conducted to analyze the miscibility of 1-icosanol and 1,1,2,2-tetrahydroheptadecafluorodecanol in the adsorbed film at the hexane/water interface. The composition of FC10OH was examined in the adsorbed film from the interfacial tension data. Experimental results indicated that the composition of the adsorbed film could be computed from the interfacial tension data and the phase diagram of adsorption.
