Solubility and Molecular Interactions of Ferulic Acid in Polyethylene Glycol PEG-200 Solution

This study examines the ultrasonic velocities and densities of dilute solutions of polyethylene glycol (PEG-200) in ferulic acid at temperatures ranging from 293.15K to 308.15K. The experimental data are used to calculate various thermo-acoustical parameters, providing insights into the molecular structure and intermolecular interactions. The solubility of ferulic acid in PEG-200 solutions is measured at 293.15K and 308.15K. Activity coefficients are determined to assess the molecular interactions between ferulic acid and PEG-200, shedding light on the solvent-solute interactions. Ultrasonic velocities and densities are measured for PEG-200 solutions in ferulic acid at various temperatures. The data are used to compute thermo-acoustical parameters, exploring the effects of temperature and mole fraction on molecular interactions. The solubility and activity coefficients of ferulic acid in PEG-200 solutions are investigated to understand the molecular interactions between the solute and solvent. These findings provide valuable information on the solution's thermodynamic properties.
