ABSTRACT

The densities and flow times of binary mixtures of N-methylacetamide with acetophenone, propiophenone, paramethyl acetophenone and parachloro acetophenone have been determined at T = 308.15 K and are employed to calculate the excess molar volumes, viscosities and deviations in viscosity over the entire range of mole fraction. All isotherms of VE as a function of composition ketones show negative deviations except propiophenone, whereas all isotherms of Dg as a function of composition of ketones record negative deviations except parachloro acetophenone. The VE and Dg values are fitted to a Redlich Kister type equation. The results are interpreted in terms of molecular interactions occurring in the solutions.
