ABSTRACT
The values of densities in N-methylacetamide solutions of magnesium chloride have been measured at atmospheric pressure using a high precision vibrating U-tube densimeter Anton Paar DMA 5000M at temperatures ranging from 308.15 K to 328.15 K, T=5 K and in the concentration range from 0 to 0.083 mol*kg-1. The kinematic viscosity for these mixtures has been measured at the same thermodynamic conditions using an Ubbelohde viscometer. Partial molar volumes of N-methylacetamide; partial molar volumes, apparent molar volumes of magnesium chloride and thermal expansion coefficients of solutions have been calculated from the experimental data. Dependences of these properties on the magnesium chloride concentrations have been discussed. Growth in the salt concentration increases the solution density and viscosity, and an increase in the temperature reduces the solution density and viscosity, at the same time. An increase in the temperature and salt concentration leads to a decrease in the magnesium chloride partial molar volume.
