Abstract:
The addition of a minor amount of a 2-hydroxy-4-alkoxythiobenzophenone or 2-mercapto-4-alkoxythiobenzophenone to olefin polymers produces an olefin polymer composition resistant to degradation by ultraviolet light.
Abstract:
A process for the conversion of olefinic hydrocarbons according to the olefin reaction including olefin disproportionation by contacting the olefinic hydrocarbon with a catalyst comprising a compound of vanadium or niobium complexed with NO and a selected complexing agent (e.g., benzoic acid) and combined with an organoaluminum compound (e.g., methylaluminum sesqui-chloride). The metal complexes which form a part of the catalysts are also claimed.
Abstract:
Acrylonitrile is photodimerized to 1,2-dicyanocyclobutane in the presence of an activator of Mo(CO)6 or W(CO)6. Preferably, a promoter such as triphenylphosphine is employed in combination with the activator.
Abstract:
A process for the synthesis of organonickel derivatives by electrochemical reduction of a nickel(II) complex followed by addition of a haloorganic compound which yields a different nickel(II) complex. The complexes have utility as catalysts for olefin dimerization.
Abstract:
A method of generating soluble zero-valent nickel catalyst consisting of electrochemically reducing suitable nickel(II)ligand complexes wherein said electrochemical reduction can be achieved with or without the presence of an electrolyte.
Abstract:
Olefin hydrocarbons are hydrogenated by contacting the feed olefin hydrocarbon with a catalyst which is an admixture of a rhodium or an iridium halide complex and an aluminum or boron halide.
Abstract:
The treatment of nickel(II) halide compounds by controlled potential electrolysis is disclosed for the production of nickel(I) halide phosphine compounds.
Abstract:
A CATALYST ACTIVE FOR THE OLEFIN REACTION INCLUDING OLEFIN DISPROPORTIONATION COMPRISING A COMPOUND OF VANADIUM OR NOBIUM COMPLEXED WITH NO AND A SELECTED COMPLEXING AGENT (E.G., BENZOIC ACID) AND COMBINED WITH AN ORGANOALUMINUM COMPOUND (E.G., METHYLALUMINUM SESQUICHLORIDE).
Abstract:
A HOMOGENEOUS CATALYST ACTIVE FOR THE OLEFIN REACTION INCLUDING OLEFIN DISPROPORTIONATION COMPRISING A COMPOUND OF RUTHENIUM, IRON, OSMIUM, RHODIUM, OR IRIDIUM COMPLEXED WITH A SELECTED COMPLEXING AGENT (E.G. TRIPHENYLPHOSPHINE) AND COMBINED WITH AN ORGANOALUMINUM COMPOUND (E.G., METHYLALUMINUM SESQUIHALIDE).
