ABSTRACT

By using laser technique, the solubility data of o-iodoaniline and p-iodoaniline in twelve pure solvents (water, methanol, ethylene glycol, ethyl acetate, hexane, cyclohexane, dichloromethane, trichloromethane, tetrachloromethane, ethanol, isopropanol and benzene) from 273K to 333K was measured. And the data was correlated with NRTL model, Apelblat equation, eh equation and van't Hoff equation. Results indicated that Apelblat equation gave the best fitting results and dissolution of iodoaniline in the solvents was endothermic.
