Abstract
The binary solid–liquid phase equilibrium for 4-(methylsulfonyl)benzaldehyde in methanol, ethanol, 1-propanol, 2-propanol, 1-butanol, acetone, acetonitrile, toluene, and acetic acid were studied experimentally within the temperatures range from (283.15 to 318.15) K under 101.3 kPa by using a static equilibrium method. With the increase in temperature, the solubility of 4-(methylsulfonyl)benzaldehyde in these solvents increased. The solubility values from high to low obeyed the following order in different solvents: acetone > acetonitrile > acetic acid > methanol > ethanol > toluene > 1-butanol > 1-propanol > 2-propanol. The modified Apelblat equation, λh equation, Wilson model, and nonrandom two liquid model were employed to correlate the experimental solubility of 4-(methylsulfonyl)benzaldehyde in the nine solvents. The calculated solubility with the modified Apelblat equation provided better agreement than those with the other three models. Generally, the regressed results by the four thermodynamic mode...
