Excess molar volumes, excess isentropic compressibilities, excess viscosities, relative permittivity and molar polarization deviations for methyl acetate +, ethyl acetate +, butyl acetate +, isoamyl acetate +, methyl propionate +, ethyl propionate +, ethyl butyrate +, methyl methacrylate +, ethyl methacrylate +, and butyl methacrylate + cyclohexane at T = 298.15 and 303.15 K

摘要

Experimental densities, dynamic viscosities, speeds of sound and relative permittivities for ten binary mixtures of methyl acetate +, ethyl acetate +, butyl acetate +, isoamyl acetate +, methyl propionate +, ethyl propionate +, ethyl butyrate +, methyl methacrylate +, ethyl methacrylate +, and butyl methacrylate + cyclohexane at T = 298.15 and 303.15 K have been measured. Applicability of Grunberg-Nissan, McAllister and Auslander equations was tested for correlating viscosity of mixtures. The suitability of free length and collision factor theories, and Nomoto and Junjie equations for predicting the speeds of sound in binary mixtures have been explored. Excess molar volumes, excess isentropic compressibilities, excess viscosities, relative permittivity and molar polarization deviations have been calculated and their compositional variation has been mathematically expressed by Redlich-Kister equation. The analysis of excess and deviation functions has been done to ascertain the predominant type of interactions in the bulk state of mixtures.
