Upgrading of renewable lignocellulose into bulk chemicals and drop-in-fuels has been identified as a state-of-the-art approach to fulfill alternative energy demands. Lignin, as the largest precursor of alkyl aromatics, can...

Integrating multifarious capabilities into a waste-free biorefinery has experienced the cornerstone for resolving tricky contraction in holistic biomass valorization. Fostering versatile utilization of industrial effluents and residual lignin from traditionally...

The solubility data of propylparaben in polar and apolar solvents were first measured at T = (283.15−323.15) K using the shake flask method. The results show that solubility of propylparaben in all selected solvents increases proportionally with temperature, and at a high temperature (323.15 K), propylparaben is most soluble in acetone, followed by isopropanol, 1-propanol, ethanol, methanol, ethyl acetate, 1-butanol, butyl acetate, methyl acetate, isobutanol, acetonitrile, and water. To mathematically represent the experimentally measured solubility data, the modified Apelblat model, Wilson model, and NRTL model were applied. The difference between experimentally measured and predicted values was described by the percentage of averaged relative deviation. The best correlation of solubility versus temperature with the highest accuracy was obtained using the modified Apelblat model. Dissolution thermodynamics of propylparaben in different solvents at different temperatures were calculated and discussed to study the dissolution mechanism of propylparaben in different solvents.
