Densities, Relative Permittivities, Excess Volumes, and Excess Molar Polarizations for Alkyl Ester (Methyl Propanoate, Methyl Butanoate, Ethyl Propanoate, and Ethyl Butanoate) + Hydrocarbons (<i>n</i>-Heptane, Benzene, Chlorobenzene, and 1,1,2,2-Tetrachloroethane) at 308.15 K and 318.15 K

Abstract

New experimental values of density and relative permittivity for alkyl esters (methyl propanoate, methyl butanoate, ethyl propanoate, ethyl butanoate) + n-heptane, + benzene, + chlorobenzene, and + 1,1,2,2-tetrachloroethane are reported at 308.15 K and 318.15 K. The relative permittivities calcuated from the measured capacitances have an uncertainty of ±0.1%. The excess volumes and relative permittivity deviation are calculated from the density and relative permittivity data. The molar and excess molar polarizations are obtained from the combination of permittivity and density data for all the mixtures at both temperatures. The results are analyzed in terms of molecular interactions.
