Molecular Interactions in Binary Mixture of Propylamine with Non-polar Solvents

Abstract

Ultrasonic velocity and density measurements for binary   mixture: I. propylamine + benzene II. propylamine + toluene   III. propylamine + o-xylene at 301.15 K have been utilized   to compute excess adiabatic compressibility, excess molar   volume, free length and available volume. These values are   reported as a function of mole fraction X1 of propylamine   β_s^E vs. X1 and V_m^E vs. X₁ plots are explained in terms of dipoledipole   interactions between two like and unlike molecules.
