Solubility of Sulfachloropyridazine in Pure and Binary Solvent Mixtures and Investigation of Intermolecular Interactions

The solubility of sulfachloropyridazine in pure methanol, ethanol, isopropanol, 1-butanol, water, acetonitrile, ethyl acetate, acetone, 1,4-dioxane and (methanol + water), (ethanol + water), and (isopropanol + water) binary solvent mixtures was determined by using a isothermal saturation method with temperatures ranging from (283.15 to 323.15) K. The descending order of the solubility in pure solvents was as follows: 1,4-dioxane > acetone > acetonitrile > ethyl acetate > methanol > ethanol >1-butanol > isopropanol > water. In three mixed solvents, the solubility of sulfachloropyridazine increased with increasing temperature and mass fraction of alcohol. At the same mass fraction of methanol, ethanol, or isopropanol and temperature, the solubility of sulfachloropyridazine in (methanol + water) was greater than that in the other mixed solvents. The obtained solubility data were correlated with modified Apelblat equation and Jouyban–Acree model. The results of correlation showed good agreement with experimen...
