  • Preparation of bromine
    Patent number: 4044113
    Abstract: Bromine is produced by reacting chlorine and ethylene dibromide in the presence of an iron halide catalyst, e.g. ferric chloride.
    Type: Grant
    Filed: February 17, 1976

    Assignee: Ethyl Corporation
    Inventor: Joseph P. Kleiman
  • Preparation of bromine
    Patent number: 3961033
    Abstract: Bromine is produced by reacting chlorine and ethylene dibromide in the presence of an aluminum halide catalyst, e.g. aluminum chloride. A small amount of bromine present prior to chlorine addition shortens the induction period. Some decomposition of the organic product occurs if it is distilled in the presence of aluminum-containing residues. These residues can be removed by water wash which can be followed by drying with H.sub. 2 SO.sub. 4 . After such treatment, ethylene dichloride can be recovered by distillation without substantial decomposition.
