ABSTRACT

Vapor pressures and standard molar enthalpies of vaporization were determined for five cyclohexyl esters: cyclohexyl formate, cyclohexyl acetate, cyclohexyl propanoate, cyclohexyl butyrate, and cyclohexyl valerate. The data were obtained from the temperature dependence of the vapor pressure measured by the Knudsen and the transpiration methods. Additionally, the standard molar enthalpies of vaporization of the same cyclohexyl esters were measured calorimetrically. An analysis of the results obtained from three independent methods has allowed us to improve the determination of the enthalpies of vaporization by the Knudsen effusion method.
