Solubility of piperonal in different pure solvents and binary isopropanol+water solvent mixtures

摘要

Using a laser monitoring observation technique, the solubilities of piperonal in different pure solvents and binary isopropanol+water solvent mixtures were determined by synthetic method from 273.15 K to 293.15 K. Results of these measurements were correlated by Apelbat equation and the combined nearly ideal binary solvent (CNIBS)/Redlich-Kister equation. The results find that Apelbat equation and the combined ideal binary solvent (CNIBS)/Redlich-Kister equation provided accurate mathematical representations of the experimental data, respectively.
