摘要: Formation of hydrous alumina in the reticules of a weak-base anion exchange resin, wherein AlCl.sub.3 has been precipitated as hydrous alumina by reaction with ammonia, is improved by employing a subsequent treatment with HCl or with NH.sub.4 Cl and HCl to convert the exchange resin to the chloride form, thereby increasing the reticular volume of the resin, thus permitting subsequent precipitation of additional hydrous alumina therein.

摘要: Ion retardation resins particularly useful for desalting caustic solutions are prepared by employing ion exchange resins consisting essentially of a mixture of a reticular, insoluble, cross-linked styrene/divinylbenzene copolymer with an entrapped non-leachable polymer of acrylic acid contained therein and where the amount of carboxylic acid groups on the polyacrylic acid are in substantial excess over the amount needed to react with all the quaternary ammonium groups which are nuclear substituted on the styrene copolymer chains.
