Volumetric, Speed Of Sound Data and Viscosity for the Binary Mixtures of 2- Methylaniline with Aliphatic Ketones and Cyclic Ketones at Different Temperatures

Abstract

Density (ρ), viscosity (η), and speed of sound (u) were measured for the binary systems of methylaniline (2-MA) with acetone (AC), methylethylketone (MEK), methylpropylketone (MPK), diethylketone(DEK), methylisobutylketone (MIBK), acetophenone (AP),cyclopentanone(CP), and cyclohexanone(CH) and their pure liquids at 298.15 K and 308.15 K over the entire composition range. By using this data, the excess molar volumes (VE), deviation in isentropic compressibility (Δκs), deviation in viscosity (Δη) were calculated. These results were fitted to the Redlich-Kister polynomial equation. The variations of these properties with composition of the mixtures suggest that the dipole –dipole interactions, hydrogen-bond and charge – transfer complex formation between 2-methylaniline and ketones. The magnitude of these properties was found to depend on the chain length and ring size of the ketone molecules.
