Equilibria between Aliphatic Acids and a Strong Base Anion Exchanger¹

Abstract

Coexisting alkoxy and alkyl free radicals undergo various reactions including alkyl-alkyl association, hydrogen atom transfer, and decomposition of the alkoxy radicals.1-3

Rigorous model for ion exchange equilibria of strong and weak electrolytes

“…The uptake of neutral and zwitter-ionic species is often not taken into account (Jones and Carta, 1993), although it does occur (Peterson and Jeffers, 1952;Peterson and Gowen, 1953;Reichenberg and Wall, 1956).…”

Uptake of Alkanes and Alcohols by Ion-Exchange Resins in Aqueous Solution

“…Peterson and Jeffers reported that a strong base anion exchanger adsorbed some aliphatic acids at higher concentrations to an extent even beyond the ion-exchange capacity. 2 Reichenberg and Wall studied the sorption of some organic acids and alcohols by strong acid cation-exchange resins and reported that the sorption was true and uniform absorption, and was not confined to the surface of the resin particles. 3 It was also reported by Davies and Owen that aliphatic and phenylacetic acids were retained in greater amounts than hydrochloric acid.…”

Uptake of Iodine and Bromine by Ion-Exchange Resins in Aqueous Solution

“…7 Some aliphatic acids at higher concentrations have been reported to exhibit high affinity for the strong base anionexchange resin beyond its ion-exchange capacity. 10 This is probably due to the contribution from the undissociated aliphatic acid, that is, partition of these hydrophobic undissociated species between the resin and the aqueous phase.…”
