Measurement and correlation of the solubility of 1-alkanols (C14, C16), in n-alkanes (C7C16)

The solubility of C14, C16 n-alkanols (1-tetradecanol and 1-hexadecanol) in hexadecane and 1-tetradecanol in heptane has been measured by a dynamic method from 290 K to the melting point. These and previous data concerning solubilities in normal alkanes (C7C15) are correlated by means of Wilson, UNIQUAC, UNIQUAC ASM and two modified NRTL equations. ot-mean-square deviations of the solubility temperatures for all calculated data vary from 0.1 to 3.2 K and depend on the particular equation used. In the calculations, the existence of two solid-solid first-order phase transitions in alkanols has also been taken into consideration.
