The solubilities of some pyrazaboles (pyrazabole, 4,4,8,8-tetraethylpyrazabole (TEP), and 4,4,8,8-tetrapropylpyrazabole) in alkanols (methanol, ethanol, 2-propanol and t-butanol) have been determined at temperatures ranging from the boiling point of the solvent to 273 K. Two correlation methods were applied : the Wilson and UNIQUAC ASM model. The best solubility correlation in alcohols was obtained with the UNIQUAC ASM KW equation, with the association constants as an adjustable parameter. In the calculations, the existence of one solid-solid first-order phase transition of TEP was also taken into consideration. The root-mean-square deviations of the solubility temperatures for all measured data varied from 2.9 to 1.9 K for the Wilson and UNIQUAC ASM models, respectively.
