N2 - The current work investigates the wax disappearance temperature (WDT) of three binary systems including n-tetradecane. +. n-hexadecane, n-hexadecane. +. n-octadecane and n-undecane. +. n-octadecane as a function of temperature at local atmospheric pressure. Verifying the uncertainties of the measurements, the WDT of pure n-hexadecane and the system n-tetradecane. +. n-hexadecane are compared with available experimental data reported in literature. Good agreement between the measured experimental data in the present study and those reported previously in literature is observed. Finally, by modeling the paraffin systems with different combinations of ideal solution behavior, regular solution theory, predictive Wilson, predictive UNIQUAC and UNIFAC, the solid-liquid equilibria of the binary systems were described to find the most accurate model without using any adjustable parameter.
