Description:
In the development of an extraction method utilizing the "salting out" technique, the extraction efficiencies of phenol, catechol, resorcinol, and hydroquinone from aqueous solutions were determined for tetrahydrofuran (THF), acetonitrile (ACN), dimethylformamide (DMF), ethyl acetate (EtOAc), and diethyl ether (Et2O). he inorganic salts of potassium fluoride (anhydrous), sodium chloride, lithium chloride, ammonium acetate, and sodium bicarbonate were used to saturate the solvent/water combinations. hase separations were not observed for THF/LiCl, NaHCO3; ACN/NaHCO3; and DMF/NaCl, LiCl, NH4OAc, NaHCO3, whereas ACN/KF produced quinone while DMF/KF yielded no hydroquinone in non-acidified solutions. ssentially all other solvent/salt combinations gave quantitative recoveries, while KF was found to be an efficient drying agent.
