  • Catalyst comprising tellurium chemically bound to aromatic polymer
    Patent number: 4558026
    Abstract: The present invention relates to a novel tellurium catalyst and its preparation, and to a process for preparing oxirane compounds using the novel catalyst. Specifically, the invention relates to a novel catalyst in which tellurium is chemically bound to a solid aromatic-type resin and to the reaction of olefinic compounds with hydrogen peroxide in the presence of the bound tellurium catalyst to produce oxirane compounds.

  • Catalytic conversion of thallium (I) to thallium (III)
    Patent number: 4115420
    Abstract: A monovalent thallium compound is converted to a trivalent thallium compound by treating the thallium (I) compound with molecular oxygen in the presence of a Group VIII noble metal catalyst to oxidize the thallium (I) compound to a thallium (III) compound.
    Type: Grant
    Filed: April 21, 1977
    Date of Patent: September 19, 1978
    Assignee: Halcon International, Inc.
