Density and Viscosity of N-Methylacetamide–Calcium Chloride Mixtures over the Temperature Range from 308.15 to 328.15 K at Atmospheric Pressure

The values of densities in N-methylacetamide solutions of calcium chloride have been measured at atmospheric pressure using an Anton Paar digital vibrating U-tube densimeter at temperatures ranging from 308.15 to 328.15 K, ΔT = 5 K and in the concentration range from 0 to 0.355 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 and apparent molar volumes of calcium chloride, and thermal expansion coefficients of solutions have been calculated using the experimental values. Dependences of these properties on the electrolyte concentrations have been discussed.
