ABILITY OF THE NITTA-CHAO MODEL FOR THE PREDICTION OF PRESSURE AND TEMPERATURE-DEPENDENCE OF THE VOLUMETRIC PROPERTIES OF N-ALKANE PLUS 1-ALKANOL SYSTEMS

Volumetric behaviour of n-alkane + 1-alkanol mixtures in a wide range of temperatures and pressures was examined on the basis of the Nitta-C hao model. Literature data of experimental densities in a temperature range from 298.15 to 373.15 K and pressures up to 40 MPa were selected in order to test the model predictions for the following quantities: excess molar volumes v(E) and isothermal compressibilities kappa(T). ( partial derivative v(E)/partial derivative T)(p) and (partial derivati ve h(E)/partial derivative p)(T) obtained from density data were compa red with those predicted with the Nitta-Chao model.
