Shukla] Experimental values of the density and ultrasonic velocity have been measured for binary mixtures of butylamine with 1-butanol and with tert-butanol at temperatures of 293.15, 303.15 and 313.15 K over the entire mole fraction range. From these data, the excess molar volumes, deviations in isentropic compressibility, excess internal pressures, and excess molar enthalpies have been calculated. All of the excess functions were fitted to Redlich-Kister polynomial relations to estimate the adjustable parameters along with the standard deviations of the fits. The variations of these excess functions with mole fraction of butylamine have been examined. The changes in these parameters with composition suggest that the interaction between butylamine and 1-butanol is strong, whereas its interaction with tert-butanol is weak. Further, the partial molar volumes and partial molar compressibilities at infinite dilution have also been evaluated since these parameters provide better insight for studying intermolecular interactions.
