Abstract: Solubilities of 2,4-dichlorobenzaldehyde in five single organic solvents,namely,n-propanol,n-butanol.cyclohexane,chloroform and dichloromethane as well as in two mixed solvents,namely,cyclohexane-acetone and cyclohexane n-butanol,have been measured.These data are correlated withWilson,NRTL and UNIQUAC activity coefficient models and can be used for the process design inthe purification of 2,4-dichlorobenzaldehyde.

Key words: solubility, solid-liquid equilibrium, thermal analysis, 2, 4-dichlorobenzaldehyde
