The solubility of 2,6-dichloro-4-nitroaniline (DCNA) in 12 pure solvents of n-butanol, n-propanol, methanol, ethylene glycol (EG), ethanol, isopropanol, acetonitrile, cyclohexane, 1,4-dioxane, ethyl acetate, water, and N-methyl pyrrolidone (NMP) was achieved through the shake-flask method at the temperatures from 278.15 to 323.15 K and ambient pressure p = 101.2 kPa. The mole fraction solubility of DCNA in the above solvents increased as the temperature increased and ranked as NMP > 1,4-dioxane > ethyl acetate > acetonitrile > n-butanol > n-propanol > ethanol > EG > isopropanol > methanol > cyclohexane > water. The solvent–solvent and solvent–solute interactions on the DCNA solubility were investigated using the linear solvation energy relationship on the basis of the solvent descriptors. The acquired solubility was correlated using the NRTL model, λh equation, modified Apelblat equation, and Wilson model. The obtained maximum relative average deviation and root-mean-square deviation were 6.53 × 10–2 and ...
