Thermodynamic solubility of piroxicam in propylene glycol + water mixtures at 298.2-323.2 K - Data report and modeling

Abstract

The solubility of piroxicam (66 data points) in binary mixtures of propylene glycol (PG) + water at six different temperatures ranging from 298.2 to 323.2 K are reported. Three different cosolvency models, i.e., the Yalkowsky, the Jouyban-Acree and a combined version of the Jouyban-Acree model with the van't Hoff approach, were used for correlating the reported data. All the results of the analyses showed an acceptable range of the error percentages.
