Density Measurement of Aqueous solution of Tetrapropylammonium Hydroxide at different Temperatures and Concentrations: Data and Correlation

摘要

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 TF.1 pressure. Derived properties, molar volume (Vm) and excess molar volumes (Vm~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 Vm~E derived properties for a binary system, Vm~E are interpreted based on intermolecular interactions.
