Abstract
Thermal expansion coefficients, ?, excess thermal expansion coefficients, ?E, isothermal coefficients of pressure excess molar enthalpy, (?HE/?p)T,x, partial molar volumes, V?i, partial molar volumes at infinite dilution, V?i?, partial excess molar volumes, V?Ei, and partial excess molar volumes at infinite dilution, V?Ei?, were calculated using experimental densities and excess molar volumes, VE, data. All calculations are performed for the binary systems of cyclohexylamine with 1-propanol or 1-butanol or 2-butanol or 2-methyl-2-propanol. The Redlich-Kister polynomial and the reduced excess molar volume approach were used in the evaluation of these properties. In addition, the aim of this investigation was to provide a set of various volumetric data in order to asses the influence of temperature, chain length and position of hydroxyl group in the alcohol molecule on the molecular interactions in the examined binary mixtures.
