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 wer e 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), respective ly. For density, experimental data were fitted by a five-parameter cor relation with a goodness of fit approximating experimental error. The presence of NaCl was found to be responsible for excess volume. For vi scosity, a five-parameter polynomial correlation gave the dependence o f dynamic viscosity on aqueous molalities and temperature, with a devi ation less than 3.8%. There was a major contribution of interaction te rms in the calculation of the ternary viscosity, particularly for the high viscosity level.
