Abstract:
High yields of aromatic, aromatic acetic and olefinic acids, esters, amides and the like are derived from a process wherein a halo-hydrocarbon is carbonylated in the presence of a palladium catalyst, a hindered amine base and phosphine in excess. The hindered amine base can comprise C₃-C₁₀ branched alkyls, cyclic compounds, or mixtures of the above. The preferred amine is N,N-diisopropylethyl amine. The preferred catalyst is PdCl₂(PPH₃)₂ with the excess phosphine generally supplied by a compound of the formula PR¹R²R³ where R¹,R² and R³ are preferably phenyl.
Abstract:
A novel catalyst system for the polymerization of alpha-olefins is provided. The catalyst system comprises:
(a) an organoaluminum containing component, e.g. triethyl aluminum, and (b) a titanium halide containing component.
The titanium halide containing component is obtained by reacting a halogen containing magnesium compound, e.g. MgCl 2 , with an organic phosphite, e.g. triphenyl phosphite, to produce a reaction product. The reaction product is then co-pulverized with a complex of a titanium halide compound and an electron donor compound, e.g. TiCl 4 ethyl benzoate, to produce a co-pulverized product. The co-pulverized product is then reacted with a titanium halide compound, e.g. TiCI 4 . A novel titanium halide containing component is provided as well as a process for producing said component. A process for the polymerization of alpha-olefins is also provided.
Abstract:
Supported organometallic compounds of Groups II, III and IV of the Periodic Table are utilized for purifying fluids particularly hydrocarbon fluids, noble gases, nitrogen and hydrogen and desirable hydrocarbon solvents and olefins to remove impurities such as oxygen, sulfur, halogen-containing compounds, active hydrogen compounds and other polar compounds. The supported organometallic compounds preferably supported metal alkyls, are prepared by reacting the pretreated dried solid support material with the organometallic compounds in such a manner as to effect loading or impregnation of the organometallic moieties onto the support.
Abstract:
A process for preparing carboxylic acid salts by the reaction of carbon monoxide with substituted or unsubstituted aromatic halides or an aliphatic organic halide comprises the catalyst single phase carbonylation of the halide utilizing in addition to carbon monoxide, a palladium catalyst, an excess of tertiary phosphine, optionally an amine compound, with an alkali metal or alkaline earth metal base added during the reaction to form the salt.

Abstract:
A titanium halide containing component suitable for use in a catalyst system comprising said component and an aluminum containing component is obtained by co-pulverizing a halogen containing magnesium compound, e.g. MgCl 2 , with an electron-donor compound, e.g. ethyl benzoate, to produce a co-pulverized product. The co-pulverized product is then reacted with an organic phosphite, e.g. triphenyl phosphite, to produce a reaction product. The reaction product is then reacted with a titanium halide compound, e.g. TiC1 4 . A catalyst system for the polymerization of alpha-olefins includes such titanium halide containing component and an organoaluminum component.
Abstract:
Catalyst system for the polymerization of alpha-olefins. The catalyst system comprises: (a) an organoaluminum containing component, e.g. triethyl aluminum, and (b) a titanium halide containing component. The titanium halide containing component is obtained by co- pulverizing a halogen containing magnesium compound, e.g. MgCl 2 , with an active hydrogen containing organic compound, e.g. phenol, to produce a co-pulverized product. The co-pulverized product is then reacted with an organometallic compound of a metal of Groups I to III of the Periodic Table, e.g. triethyl aluminum, to produce a reaction product. The reaction product is then co-pulverized with a complex of a first titanium halide compound and an electron-donor, e.g. TiCl 4 .ethyl benzoate, to produce a solid reaction product. The solid reaction product is then reacted with a second titanium halide compound, e.g. TiCl 4 .
