  • Light metal oxide-based amorphous conductor
    Patent number: 5108658
    Abstract: The invention relates to a light metal oxide-based amorphous electrical conductor which comprises an amorphous ternary composition consisting of alumina, boria, and an oxide of a light metal selected from Group IA and IIA of the Periodic Table of Elements. Amorphous conductors of the present invention can be produced by forming an aqueous composition comprising a source of light metal ions, a source of alumina and a source of boria to form a homogeneous gel, drying the gel to form a superifically dry solid, and calcining the dry solid at a sufficiently high temperature to form an amorphous ternary composition as described above. The conductor is used as an element of a moisture and/or a high temperature sensor.

  • Selective para-ethylation of toluene with magnesium compound-impregnated, crystalline, gallosilicate based, molecular sieve catalyst compositions
    Patent number: 4812536
    Abstract: Described are magnesium compound-impregnated catalyst compositions comprising a gallium-modified, crystalline silica molecular sieve, essentially free of aliminum, composited in an inorganic matrix. Said compositions are useful fro hydrocarbon conversion, particularly the selective ethylation of toluene in which they exhibit extremely high paraselectivity at an excellent percent conversion.

    Date of Patent: March 14, 1989
    Assignee: Amoco Corporation
    Inventors: Richard E. DeSimone, Lori B. Lane
  • Propylation of toluene with a high surface area, zinc-modified, crystalline silica molecular sieve
    Patent number: 4670617
    Abstract: Described are catalyst compositions comprising a high surface area, zinc-modified, crystalline silica molecular sieve, essentially free of aluminum, which has been incorporated into an inorganic matrix; said compositions are useful for hydrocarbon conversion, particularly the propylation of toluene in which they exhibit a very high paraselectivity while making a product containing a high isopropyltoluene/n-propyl-toluene isomer ratio. These catalyst compositions are made from an organic base, a templating material, a zinc ion-affording compound, and an oxide of silicon.

  • Selective ethylation of xylene with a metal-modified, crystalline borosilicate molecular sieve
    Patent number: 4652691
    Abstract: Described is a process for selectively converting xylene in the gas phase with an ethylating agent under hydrocarbon conversion conditions to a highly pure 3,4-dimethylethylbenzene product in the presence of a catalyst composition comprising a metal-ion-modified, crystalline borosilicate molecular sieve in which the metal is intimately associated with the framework silica lattice, composited in an inorganic matrix.
