Abstract: A process of separating carboxylic acids comprising two steps. The first step is to provide an aqueous solution comprising (i) one or more mono-carboxylic acids, (ii) one or more di-carboxylic acids, and (iii) one or more tri-carboxylic acids. The second step is to pass the aqueous solution through a collection of resin particles, where the resin particles comprise covalently bound quaternary ammonium groups, and wherein the collection of resin particles has uniformity coefficient of 1.5 or less.
