How does p-methoxybenzoic acid (PMBA) solubility vary with temperature and ethanol mass fraction?

Label:chem

Topic
Solubility was measured using the static method for ethanol mass fractions of 0.6, 0.8, and 1.0 at 293.15–323.15 K.
Answer
Solubility increases with temperature and ethanol mass fraction. The dissolution enthalpy decreases with increasing ethanol mass fraction (0.6 > 0.8 > 1.0), indicating reduced solvation intensity.
