“…90 Both the hydrotrope itself and the solute influence the MHC and C max of hydrotropes, which are useful in predicting the recovery. 44,106,108,109 Therefore, the MHC and C max are worth considering with lignin solubilization together to achieve the economic feasibility of hydrotropic systems in biomass processing.…”

Strong self-association of hydrophobic solutes takes place in water. However, solute selfassociation has often been neglected in understanding the aqueous solubility of drugs as well as their solubilization by excipients, cosolvents and hydrotropes. Based on a rigorous statistical thermodynamic foundation, here we show how to estimate the contribution from solute selfassociation to solubility and solubilization, based on experimental data such as solubility and the osmotic second virial coefficients. Such data show that solute self-association can indeed be negligible in most common cases of hydrotropic solubilization, Setschenow coeffficients and the hydrophobic hydration.

The effect of hydrotropes such as sodium salicylate, sodium benzoate, and nicotinamide on the solubility and mass transfer coeffi cient of benzoic acid has been investigated. The solubility studies were carried out under a wide range of hydrotrope concentrations (0 to 3.0 mol/L) and different system temperatures (303K to 333K). It has been observed that the solubility and mass transfer coeffi cient of benzoic acid increases with an increase in hydrotrope concentration and also with system temperature. A Minimum Hydrotrope Concentration (MHC) was found essential to initiate a signifi cant increase in the solubility and the mass transfer coeffi cient. The maximum enhancement factor (φ s ), which is the ratio of the solubility value in the presence and absence of a hydrotrope, has been determined for all sets of experimentations. The solubility of benzoic acid has been enhanced to 19.98 times in the presence of 2.5 mol/L concentration of sodium salicylate hydrotrope at 333K.The effectiveness of hydrotropes was measured in terms of Setschenow constant K s and the highest value has been observed as 0.502 for sodium salicylate.
