Thermodynamic study on phase transition in adsorbed film of fluoroalkanol at the hexane/water interface. 7. Pressure effect on the miscibility in the adsorbed film of alkanol and fluoroalkanol mixture
Article Abstract:
The pressure dependence of interfacial tension at various compositions was measured and the experimental results were analyzed thermodynamically through the study of the miscibility of 1-icosanol (C20OH) and 1,1,2,2-tetrahydroheptadecafluorodecanol (FC10OH) in the adsorbed film at the hexane/water interface. It was found that the alcohol molecules become less miscible and therefore the activity coefficients of alcohols become larger in the expanded state with increasing pressure.

Calorimetric study of dilute aqueous solutions of ethylene glycol oligomers
Article Abstract:
A study was conducted to analyze dilute aqueous solutions of ethylene glycol oligomers. Thermodynamic equations were applied to experimental results to evaluate the differential enthalpies of the solution. Experimental results indicated that the distance between the oxygen atoms for the helical conformation of ethylene glycol oligomers in the crystalline state was similar to that of liquid water.

Calorimetric study of micellar solution of pentaethylene glycol monooctyl and monodeccyl ethers
Article Abstract:
The enthalpy of micelle formation of C8E5 and C10E5 are obtained at seven temperatures by measuring the enthalpies of mixing of C8E5 in water and of aqueous solution of C10E5 in water. It is found that the enthalpies of micelle formation of C9E5 and C10E5 are positive and decrease with increasing temperature.
