C07F 708
US Classification:
556479
Abstract:
A process for producing an organosilane including reacting an alkene halide with a hydrogen silane in the presence of a hydrosilating catalyst. The alkene halide is present in an amount such that a molar excess of at least 5 moles per one mole of hydrogen silane is maintained.

Assignee:
Dow Corning Corporation - Midland MI
International Classification:
C07F 7/14
US Classification:
556479, 556414
Abstract:
This invention involves a process for the preparation of haloalkylalkoxysilanes and haloalkylhalosilancs. The process comprises reacting an alkoxyhydridosilane or a halohydridosilanc silane with an alkenylhalide compound in the presence of a catalytic amount of an iridium containing catalyst. When a halohydridosilane is the silane reactant. The resulting haloalkylhalosilane may be alkoxylated by reaction with a C-C, alcohol. In another aspect of the invention, the reacting is conducted under a reduced oxygen atmosphere to improve the catalyst activity and the yield of the resulting haloalkylhalosilane or haloalkylalkox vsi lane.

US Classification:
556479
Abstract:
A hydrosilation process comprising contacting a silicon hydride with an unsaturated reactant in the presence of a platinum catalyst supported on porous aluminum oxide having an acidity of pH 2 to 7. The process is particularly useful for the hydrosilation of unsaturated reactants where the unsaturation is in the internal portion of the reactant's structure, for example, as in cyclopentene and cyclohexene.
Process For Preparation Of Bis- And Tris(Silylorgano)Amines

Assignee:
Dow Corning Corporation - Midland MI
International Classification:
C07F 710
US Classification:
556413
Abstract:
The present invention is a process specific for the preparation of bis- and tris- amines by the contact of silylorganoamines in the presence of palladium monoxide catalyst. The process results in near quantitative conversion of the silylorganoamines to the desired bis- and tris-amines, without the need for elevated pressures and without formation of salts of ammonia and chloride.

US Classification:
556443
Abstract:
The present invention is a method for separating silyl ketene acetals from carbonyl by-products having a terminal olefinic bond and a boiling point similar to that of the silyl ketene acetals. The method employs a platinum catalyst which specifically effects hydrosilation of the carbonyl by-product's terminal olefinic bond by an organohydrosilane. The platinum catalyst is the reaction product of hexachloroplatinic acid and sym-tetramethyldivinyldisiloxane. In a preferred method the silyl ketene acetal is separated from the hydrosilated carbonyl by-product by distillation.

International Classification:
C07F 708
US Classification:
556453
Abstract:
This invention relates to a process for the manufacture of a silane or polyorganosiloxane containing a cycloalkyl substituent by hydrogenation of a silane or polyorganosiloxane containing at least one aromatic hydrocarbon substituent in the presence of a Raney nickel catalyst without a solvent.
Palladium Black Catalyzed Process For Preparation Of (Piperazinylorgano) Silanes

Assignee:
Dow Corning Corporation - Midland MI
International Classification:
C07F 710
US Classification:
544229
Abstract:
The present invention is a process for the preparation of (piperazinylorgano)silanes. The process involves the contact of an (aminoorgano)silane with piperazine or an organopiperazine, in the presence of palladium black as a catalyst. The process is run at a temperature within a range of about 50. degree. C. to 300. degree. C. in a standard low-pressure type reactor.
Process For Preparation Of Primary Aminoorganosilanes

Assignee:
Dow Corning Corporation - Midland MI
International Classification:
C07F 710 C07F 718
US Classification:
556413
Abstract:
The present invention is a process for the preparation of primary aminoorganosilanes. The process comprises contacting an cyanoorganosilane with hydrogen gas in the presence of a supported cobalt catalyst. The result of this process is a near quantitative conversion of the cyanoorganosilane to a primary aminoorganosilane. The apparent rate and yield of the process can be improved by use of an organic solvent, without effecting specificity for the primary aminoorganosilane.
