  • Process for preparing a supported silver catalyst
    Patent number: 4455392
    Abstract: This invention relates to a supported silver catalyst for the manufacture of ethylene oxide prepared by a process comprising impregnating a porous catalyst support with a solvent containing a silver salt and treating the impregnated support to effect deposition of silver on the support surface. Following silver deposition, the support is impregnated with a liquid containing more than 30%, by volume, of an organic solvent capable of forming a complex with silver ion, and a compound of at least one metal promoter in an amount sufficient to deposit the desired amount of metal cation on said support. The impregnated support is then treated to effect deposition of the promoter. There is also described herein a process of making such catalyst and a process for producing ethylene oxide.
    Type: Grant

    Assignee: Union Carbide Corporation
    Inventors: Glenn H. Warner, Madan M. Bhasin, Bernard Lieberman
  • Stabilized acetal-acid compositions
    Patent number: 4448977
    Abstract: A storage stable composition of glutaraldehyde acetals and an organic acidic catalyst, which can be converted to glutaraldehyde at the site and upon demand, by the addition of water.
    Type: Grant
    Filed: August 26, 1982
    Date of Patent: May 15, 1984
    Assignee: Union Carbide Corporation

  • Silver catalyst for the manufacture of ethylene oxide and a process for preparing the catalyst
    Patent number: 4419276
    Abstract: This invention relates to a supported silver catalyst for the manufacture of ethylene oxide prepared by a process comprising impregnating a porous catalyst support with a solvent containing a silver salt and treating the impregnated support to effect deposition of silver on the support surface. Following silver deposition, the support is impregnated with a liquid containing a compound of at least one metal promoter dissolved in an organic solvent in which water is soluble at ambient temperature in an amount no greater than about 50 wt. % based on the weight of the water-solvent solution. The impregnated support is then treated to effect deposition of the promoter. There is also described herein a process of making such catalyst and a process for producing ethylene oxide.
