  • Patent number: 4732946
    Abstract: A process for the preparation of chelation resins is disclosed. By this process, chelation resins can be prepared without the formation of large amounts of waste salt streams. In addition, novel chelation resins are prepared according to this process.
    Type: Grant

    Assignee: The Dow Chemical Company
    Inventors: George R. Killat, Edward R. Husser
  • Patent number: 4399235
    Abstract: High density, ion exchange resins having excellent integrity are prepared from cross-linked, aromatic polymers which have been halogenated in the presence of an organic liquid having a sufficiently high dielectric constant to prevent substantial halogenation of the polymer backbone such as various organic nucleophiles having a free electron pair associated with a nonhalogen atom, e.g., ethanol or dimethylformamide. For example, a cross-linked polystyrene which has been brominated in methylene chloride containing a small amount of ethanol can subsequently be chloromethylated and aminated to form a high density anion exchange resin useful in removing anions from thick slurries such as those employed in uranium recovery.
