Measurement and Correlation of Solubility of o -Nitrobenzaldehyde in Four Binary Solvents from 273.15 to 313.15 K
Abstract
The mole fraction solubility of o -nitrobenzaldehyde was measured in four binary aqueous–alcoholic solvent systems (methanol–water, ethanol–water, n -propanol–water, and isopropanol–water) by the laser dynamic method over the temperature range of 273.15–313.15 K. The results showed that the solubility of o -nitrobenzaldehyde increases with both rising temperature and increasing mole fraction of the alcoholic component. The solubility data were correlated using the modified Apelblat model, the Yaws model, the Van’t Hoff–Jouyban–Acree model, and the Wilson model. Among these, the modified Apelblat model provided significantly superior correlation results compared to the other models. The calculated Hansen solubility parameters indicated that hydrogen bonding energy plays a predominant role in the mixing process.
