摘要：

The uptake of carboxylic acids and phenols by an anion exchange resin is studied from aqueous solutions containing acetone or methanol. Distribution coefficients are higher in basic solutions where the acid anion predominates, but a significant uptake also occurs from acidic solution. A higher proportion of organic solvent in the solution lowers the distribution coefficients. Several practical separations are demonstrated on short columns. Distribution coefficients and capacity measurements are reported for organic acids on a nonionic polystyrene resin and compared with those for the polystyrene anion exchange resin. Also, uptake of organic acids by a quaternary ammonium salt dissolved in cyclohexane is determined and compared with the two resins studied. © 1968, American Chemical Society. All rights reserved.
