Transport Properties of Diethyl Malonate with Aniline and Benzaldehyde at 308.15 and 318.15 K

Abstract

Densities, viscosities and ultrasonic velocities of binary liquid mixtures of diethyl malonate with aniline and benzaldehyde have been measured at 308.15 and 318.15 K. From these data, excess volume (V E ), deviation in isentropic compressibility (∆KS), deviation in viscosity (∆η), deviation in intermolecular free length (∆Lf), deviation in free volume (∆Vf), deviation in internal pressure (∆πi) and deviation in acoustic impedance (∆Z) have been calculated. These results were correlated with the Redlich and Kister type polynomial equation to derive the coefficients and standard errors. Variations in the calculated excess quantities have been studied for mixtures of diethyl malonate with component liquids. From the value of excess properties, intermolecular interactions have been studied.

Thermodynamic Properties of Binary Liquid Mixtures Containing Furfural with Chlorobenzene, Nitromethane, Diethylmalonate and 1-Butanol at 308.15K and 318.15K Supported by FTIR Spectral Studies

“…Nitromethane (SRL, Mumbai, purity >99%), 1-butanol (Thermo fisher scientific, Mumbai, Purity >99%), were purified by distillation, and furfural (SRL, Mumbai, Purity >99%), and diethylmalonate (SRL, Mumbai, Purity >99%) were used without further purification. The purity of the pure compounds was also confirmed by comparing the measured density, viscosity, and ultrasonic velocity of the pure compounds at various temperatures with those described in the literature, which showed a fair agreement and is listed in Table 1 [9][10][11][12][13][14][15].…”
