Solubilities of 5,10,15,20-tetrakis(4-chlorophenyl) porphyrinmanganese(III) chloride in N,N-dimethylformamide + water mixtures

摘要

The solubility of 5,10,15,20-tetrakis(4-chlorophenyl) porphyrin manganese(III) chloride (abbrevi-ated in p-ClTPPMnCl) in N,N-dimethylformamide (abbreviated in DMF) + water solvent mixtures at293.2-353.2 K were measured. The effects of mass fraction of DMF in the solvent mixtures at 1.00-0.80on the solubility were studied. The results show that the solubility decreases with the decreasing massfraction of DMF at constant temperature, and increase with the increasing temperature at constant sol-vent composition. The experimental data were correlated with Apelblat equation, and the solubilitiescalculated by the model were in good agreement with experimental observations.
