    Abstract: A process is disclosed for recovering isoflavones from a soy extract comprises: dripping the soy extract dissolved in the aqueous solvent through a chromatographic column from top to bottom packed with a ground highly polar cationic exchange resin containing sulfonic acid functional groups of the formula: {MHSO.sub.3 }--Na wherein MH is the particular adsorbent resin on which the sulfonic acid functional groups are immobilized and wherein the resin is charged with sodium ions which replace the hydrogen ions of sulfonic acid, to selectively adsorb the 7-glycosyl-isoflavones directly on the sulfonate sulfur atom while the undesired proteins and glycosides other than the 7-glycosyl-isoflavones are eluted through the chromatographic column and are removed.

    Abstract: Spent aqueous alkanolamine solution containing free alkanolamine, alkali metal salts of anions which form heat stable salts with such alkanolamine and heat stable alkanolamine salts is reactivated by contacting the solution with an acidic cation ion exchange resin to remove alkali metal cations and alkanolamine cations resulting from (1) protonation of free alkanolamine with hydrogen on the resin and (2) the alkanolamine salts, followed by eluting the resin with aqueous ammonia to preferentially displace alkanolamine from the resin and thereafter eluting the resin with a dilute mineral acid to displace the ammonia, metal cations and any remaining alkanolamine. The displaced alkanolamine is recovered for reuse. The aqueous ammonia may also be recovered for reuse.

    Abstract: Water is demineralized by passage through a water demineralization system. The water demineralization system comprises a series of at least three ion exchange resin zones. The sequential series comprises a strong acid cation (SAC) resin zone, a first anion resin zone, and a weak acid cation (WAC) resin zone. The SAC resin zone comprises a SAC resin for removing cations from the water, the first anion resin zone comprises an anion resin for removing anions from the water, and the WAC resin zone comprises a WAC resin for removing cations from water without substantially splitting any salts present in the water. Means for connecting each resin zone in the series are provided so that water can pass sequentially through the system. A method is also provided for regenerating the WAC resin from sodium and ammonium exhaustants. This method comprises contacting the WAC resin with an aqueous solution of a regenerant that is substantially devoid of sulfur and halogen groups. The regenerant is selected from the group consisting of (a) organic acids, (b) inorganic acids, (c) amine salts of (a) and (b), (d) amines, and (e) combinations thereof.

    Abstract: A process for treating wash water from the manufacture of terephthalic acid, wherein the wash water includes terephthalic acid, metal catalyst, and organic acid byproducts. The process includes the steps of passing the wash water through a filter medium to remove undissolved terephthalic acid solids, passing the filtered water through a cation exchange resin in hydrogen ion form to remove the metal catalysts, and passing the water through an anion exchange resin to remove dissolved terephthalic acid and dissolved organic acid byproducts. The treated water and certain components removed from the wash water are recovered and reused in the manufacture of additional terephthalic acid. An apparatus in which the process is practiced is also described and, after a quantity of wash water has been treated, the apparatus is regenerated with regenerants that are also recovered and reused in the manufacture of additional terephthalic acid.
