Excess molar volumes and viscosities for binary liquid mixtures of methyl tert-butyl ether and of tert-amyl methyl ether with methanol, 1-propanol, and 1-pentanol at 298.15 K

Excess molar volumes V-m(E) and viscosities eta have been measured as a function of composition for binary liquid mixtures of methyl tert-butyl ether and of tert-amyl methyl ether with methanol, 1-propanol, and 1-pentanol at 298.15 K and atmospheric pressure. The excess volumes V-m(E) are negative for all the mixtures over the entire range of composition. From the experimental results, the deviation in the viscosity (Delta ln eta) has been calculated. These properties are fitted to the Redlich-Kister equation to estimate the binary coefficients. The results for V-m(E) and Delta ln eta are discussed on the basis of molecular interactions between the components of the mixtures.
