Thermophysical Properties of Acetophenone with Ethylchloroacetate at Temperatures of 303.15, 313.15 and 323.15 K

Abstract

Densities, viscosities, refractive indices and speed of sounds of the binary mixtures of Acetophenone with Ethyl- chloroacetate were measured over the entire mole fractions at (303.15, 313.15 and 323.15) K. From these experimental results, excess molar volume V E , viscosity deviation ∆η, refractive index deviation ∆nD, deviations in speed of sound ∆u, deviations in isentropic compressibility ∆ks and excess intermolecular free length ∆Lf were calculated. The viscosity data have been cor- related with the equations of Grunberg and Nissan, Hind et al., Tamura and Kurata, Katti and Chaudri, Sedgwick, Krishnan- Laddha and McAllister. The thermo physical properties under study were fit to the Jouyban-Acree model. The excess values were correlated using Redlich-Kister polynomial equation to obtain their coefficients and standard deviations. It was found that in all cases, the data obtained fitted with the values correlated by the corresponding models very well. The results are interpreted in terms of molecular interactions occurring in the solution.
