“…The CPA–EOS is a powerful tool for thermodynamic modeling of associating components as well as nonassociating components, and it has been successfully applied into many mixtures. − This equation of state combines the simplicity of a cubic EOS, that is, the Soave Redlich Kwong (SRK) equation, and the association term from the Wertheim theory, as that used in statistical association fluid theory (SAFT). The results are accurate because this equation of state models the association part of the components in the mixtures, unlike the cubic equations of state.…”

In this paper, experimental values of densities, speeds of sound, and refractive indices in a temperature range of 293.15−323.15 K have been measured as a function of composition for the binary liquid mixtures of 1,2dimethoxyethane with alcohols such as methanol, propan-1-ol, propan-2-ol, and butan-2-ol. From these experimental values, excess/derived properties such as excess molar volume, isentropic compressibility, deviation in isentropic compressibility, and deviation in the refractive index have been calculated. Excess/derived properties have been correlated using the Redlich− Kister equation and physicochemical properties modeled using the cubic plus association equation of state for pure and binary mixtures. The results are interpreted with respect to possible molecular interactions between components.
