Density, viscosity and ultrasonic velocity study: Binary mixtures of 3-bromoanisole and methanol at different temperatures

Abstract

The values of density, viscosity and ultrasonic velocity at three different temperatures (303.15, 313.15 and 323.15 K) of the prepared binary mixture solutions with different compositions of 3-bromoanisole (3-BA) and methanol (MeOH) are experimentally determined and presented. Moreover, the excess values of molar volume, viscosity and ultrasonic velocity have been determined. These determined excess properties are fitted to the Redlich-Kister equation. Deviations from the linearity are found in the experimentally measured parameters with variation in mixture composition and are interpreted in terms of molecular interaction. Moreover, thermodynamic properties are evaluated to understand the dynamic behavior of the system.
