Excess Volumes of Ethyl Acetate + Toluene, + o-Chlorotoluene, and + p-Chlorotoluene from 283.15 to 303.15 K

Abstract

Excess volumes (V®) of binary mixtures of ethyl acetate with toluene and its o-and p-chloro derivatives have been determined from density measurements from 283.15 to 303.15 K over the entire composition range. Excess volumes are negative for all mixtures at all temperatures. The V*• values are close to zero for the ethyl acetate + toluene system. The values decrease in the order toluene, o-chlorotoluene, and p-chlorotoluene. The effect of temperature on the excess volume is ( dVE/dT)p, being generally negative.

Thermodynamic Properties of Water + Ethylene Glycol at 283.15, 293.15, 303.15, and 313.15 K

“…Excess volumes and viscosities at 308.15 K have been reported by Reddy et al (1994), excess volumes, viscosities, and refractive indices at 298.15 K by Aminabhavi and Gopalakrishna (1995), and surface tension at a series of temperatures by Hoke and Chen (1991). As a part of a program in progress in our laboratory, which concerns the study of thermodynamic properties of binary organic solutions (Palaiologou and Molinou, 1995;Palaiologou, 1996), we report a systematic study of excess volumes (V E ), viscosity deviations (∆η), refractive index deviations (∆R) and surface tension excess (σ E ) of aqueous ethylene glycol mixtures at (283.15, 293.15, 303.15, and 313.15) K. The data cover the entire range of composition at 10% mass intervals.…”

Densities, Viscosities, and Refractive Indices of Some Alkyl Esters with 4-Chlorotoluene Systems at (293.15, 298.15, and 303.15) K

“…Introduction of a Cl group into the toluene molecule may influence both the sign and magnitude of excess properties. As a continuation of previous work in our laboratory (Palaiologou and Molinou, 1995) we here report excess volumes V E , deviations in viscosity from a mole fraction average, ∆η, and deviations in refractive index from a volume fraction average, ∆R, for binary mixtures of 4-chlorotoluene + methyl acetate, +ethyl acetate, and +propyl acetate, at (293.15, 298.15, and 303.15) K.…”

Electron Releasing Effect on the Thermodynamic and Transport Properties of Liquid Mixtures at Various Temperatures

“…This fact signifies decreasing dipole-dipole interaction due to decreasing proton donating ability with increasing chain length of 1-alkanols. It also suggests the rupture of hydrogen bonded chain of the dipolar interactions between N,N-diethyl aniline and 1-alkanol exceed the [42,43] as the carbon chain increases and also decreases in proper dipole alignment of the components.…”
