  • Hydroformylation process
    Patent number: 4155939
    Abstract: This invention provides a novel hydroformylation catalyst which is a ligand stabilized complex of platinum dihalide dimer and stannous halide.A preferred species of the invention hydroformylation catalyst can be represented by a formula corresponding to the chemical structure: ##STR1## wherein R is an organic radical such as alkyl or aryl, and X is a halogen radical.
    Type: Grant
    Filed: November 21, 1977
    Date of Patent: May 22, 1979
    Assignee: Celanese Corporation
    Inventor: John E. Poist
  • Platinum-tin hydroformylation catalyst
    Patent number: 4152357
    Abstract: This invention provides a novel hydroformylation catalyst which is an ionic combination of a quaternary ammonium component and a ligand stabilized complex of platinum dihalide and stannous halide.A preferred species of the invention hydroformylation catalyst can be represented empirically by the chemical structure: ##STR1## wherein R and R' are organic radicals such as alkyl and aryl, and X is a halogen radical.The present invention stabilized platinum-tin complex hydroformylation catalyst provides a faster reaction rate at lower pressures and a superior combination of a high level of olefin conversion and efficiency to aldehyde products than prior art hydroformylation catalysts.

  • Coagulation of epoxy ester-acrylic emulsions
    Patent number: T968001
    Abstract: a coating coagulation bath is disclosed containing an emulsified graft copolymer of an epoxy ester and an alpha beta ethyleneically unsaturated monomer. The bath itself is self-coagulatable in that a metal panel dipped into the bath will exhibit a coating on its surface immediately after removal.
