Abstract
ABSTRACT The extraction equilibrium of 2-chlorophenol from an aqueous solution by the sulfuric acid salts of trioctylamine (TOA sulfate salts, or TOA salts) in an organic solvent was investigated. Sulfuric acid first reacts with trioctylamine (TOA) to form the TOA salts; then 2-chlorophenol is extracted into the organic phase from the aqueous phase by the TOA salts. The modified Wilson model, which accounts for the equilibrium of the chemical reaction of trioctylamine and sulfuric acid to form the various TOA salts, was applicable to the reaction in any organic solvent at various temperatures to predict the extraction of 2-chlorophenol. The number of water molecules accompanying the various TOA salts, which reflects the extraction capability of 2-chlorophenol, was determined. The results obtained from the modified model of equilibrium of the chemical reaction of trioctylamine and sulfuric acid are fairly consistent with the experimental data. The effects of the initial concentration of 2-chlorophenol, inorganic acids and organic solvents on the distribution coefficient of 2-chlorophenol were investigated.
