ABSTRACT
Physicochemical properties of pure liquids and their liquid mixtures at different compositions and at different temperatures have a significant role in the optimisation of chemical processes. Present report involves the analysis of the physicochemical properties of 1,3-diaminopropane and alkyl acetate. The viscosity () and refractive index (
) of 1,3-Diaminopropane, 1,3-DAP (1), with alkyl acetates, AAc, (C1-C4) (2) were measured at different temperatures (T = 303.15 to 318.15 K) under the atmospheric pressure 0.1 MPa. Deviation in viscosity,
, deviation in refractive index,
, and excess Gibbs free energy of activation,
for these binary mixtures were calculated from measured viscosity and refractive index data and fitted to Redlich-Kister polynomial equation (R.K.). The
data were analysed in terms of the Graph theoretical approach (GTA) to study the interactions in binary mixtures. The
values were also correlated by using Bloomfield and Dewan (BFD) model and various correlations.
data were correlated by various relevant correlations.
