ABSTRACT
Densities of the binary mixtures consist of methanol, ethanol, 1-propanol, 1-butanol and 1-pentanol with diisopropylamine were measured at temperatures (293.15, 298.15, 303.15 and 313.15) K and atmospheric pressure. Data were used to calculate the excess molar volumes. All the excess molar volumes are large and negative over the whole range of mole fraction, indicating strong interactions between unlike molecules. The ERAS-model has been applied for describing the binary excess molar volumes. The ERAS parameters confirm that the strong interactions between unlike molecules are encountered in mixtures. Also The Peng Robinson Stryjek Vera (PRSV) equation of state has been used to predict the binary excess molar volumes.
