| abstract | 1471729 Ion exchange resin compositions DOW CHEMICAL CO 1 Oct 1974 [2 Oct 1973] 42589/74 Heading B2E A composition for exchanging ions comprises a substrate of particles of insoluble synthetic resin having exchanging sites on its available surface, the surface being coated with insoluble synthetic resin particles having ion exchange sites on their outer surface which attract the available sites on the substrate, wherein the coating particles constitute a monolayer irreversibly attached to the substrate, the substrate has a particle size of 5 to 100Á, and the coating particles have a median diameter of 0.1 to 5Á. The coating particles may have a size range of 0.01 to 10Á. A slurry of substrate particles packed in an exchange column is preferably coated in situ by passing a suspension of coating particles through the column. The material of the substrate or the coating may be macroporous or gel-type resins, and may be derived from polyacrylic, polymethacrylic, polyvinylaromatic or phenol / formaldehyde resins treated to be anionic or cationic exchange resins, e.g. styrene/divinylbenzene copolymer containing 2 to 8 wt.% of divinylbenzene treated to form the sulphonate or a quaternary ammonium derivated thereof. Cationic exchange resins are coated with anionic exchange resins and vice versa, and the term "cationic exchange resins" embraces chelating exchange resins. In Examples the chromatographic use of specific resins in delaying the passage a series of cations or a series of anions is described. A method of separating resin particles of the required size ranges is also described. |
