The effect of hydrotropes potassium p-toluene sulfonate (KPTS), citric acid, and nicotinamide on the solubility and mass-transfer coefficient of 1,2-dihydroxy-9,10-anthraquinone (alizarin) was studied. Solubility studies were carried out under a wide range of hydrotrope concentrations (0 to 3.0...

The reactivity of the hydroxypropyl units was demonstrated by the esterification of porphyrazine derivatives with 3,5-bis(trifluoromethyl)benzoic acid in the presence of dicyclohexylcarbodiimide and toluene-p-sulfonic acid. The symmetrical porphyrazine derivatives with eight ester units were soluble in ...
Lennard-Jones (LJ) contributions to hydration free energies were small, being more significant for toluene due to cavity formation. The estimated Gibbs free energy of hydration presented an exponential trend for benzoic acid and (+)-catechin when compared to experimental solubility data. These trends...
The solubility of the investigated cocrystal slightly increased when adding small amounts of anti-solvent to the solvent, but drastically decreased for high anti-solvent amounts. Furthermore, the solubilities of nicotinamide, succinic acid and the cocrystal in the considered solvent/anti-solvent ...
