Densities and viscosities of ternary systems of NaCl-sucrose-water from 283.15 to 303.15 K

Densities and viscosities of ternary systems of NaCl-sucrose-water were measured in the range 283.1 to 303.1 K. NaCl and sucrose molalities ranged from 0 to 6 mol . kg(-1) and 0 to 5.55 mol . kg(-1), respectively. For density, experimental data were fitted by a five-parameter correlation with a goodness of fit approximating experimental error. The presence of NaCl was found to be responsible for excess volume. For viscosity, a five-parameter polynomial correlation gave the dependence of dynamic viscosity on aqueous molalities and temperature, with a deviation less than 3.8%. There was a major contribution of interaction terms in the calculation of the ternary viscosity, particularly for the high viscosity level.
