AbstractThe solubility of substituted pyrazaboles: 1,3,5,7-tetramethylpyrazabole (TMP) and 1,3,5,7-tetramethyl-4,4,8,8-tetraphenylpyrazabole (TMTFP) in methanol, ethanol, 2-propanol, tert-butanol and toluene have been determined by a dynamic method at temperatures ranging from the boiling point of the solvent to 285 K. Introduction of the substituents to a pyrazabole molecule strongly decreases the solubility in alcohols. The results have been correlated by the Wilson. UNIQUAC and UNIQUAC ASM equations. The best results were obtained for UNIQUAC ASM equation with the average root mean square deviation delta=1.5 K.
