    Inventors: Biau-Hung Chang, Ronnie M. Hanes
  • Patent number: 4707500
    Abstract: Crystalline ferroborosilicate compositions are prepared from a silica containing mixture by digesting a reaction mixture comprising a tetraalkylammonium compound, a sodium hydroxide, a boron compound, an oxide of silicon, an iron ion source, an optional chelating agent and water to provide the crystalline ferroborosilicate which is then palladium ion-exchanged. This composition may be used alone or physically mixed with a methanol catalyst. Conversion of synthesis gas, dimethylether, ethylene and methanol to low molecular hydrocarbons employing these new ferroborosilicates as catalysts is also disclosed.
    Type: Grant

    Inventors: James A. Hinnenkamp, Vernon V. Walatka
  • Patent number: 4191669
    Abstract: Polyamides suitable as hot-melt adhesives and containing groups derived from a polymeric fatty acid containing 70-90% by weight of dimer acid and from a triamine of the structure ##STR1## in which R.sub.1 is a C.sub.1 -C.sub.3 alkyl group and R.sub.2 and R.sub.3 are bivalent hydrocarbon radicals. Optionally the polyamide also contains groups derived from a C.sub.2-20 diamine, a dicarboxylic acid containing 6-12 carbon atoms, a monocarboxylic acid or a C.sub.5-12 lactam.
