Abstract

Abstract: Densities of aqueous Tetrapropylammonium hydroxide solution (5, 10, 15, 20 and 25 wt %) were invistigated over a temperature range of 298.15 to 333.15 K and at atmospheric pressure. Derived properties, molar volume ( Vm ) and excess molar volumes ( V m E ) were estimated and correlated with temperature using the least square method. The predicted values from correlations are in good agreement with measured values. The obtained results from derived properties for a binary system, V m E are interpreted based on intermolecular interactions.
