Method For Producing Ketimine Structure-Containing Alkoxysilane

View page
US Patent:
7923572, Apr 12, 2011
Filed:
Sep 21, 2006
Appl. No.:
12/067746
Inventors:
Yoshinori Taniguchi - Chiba, JP
Makoto Iwai - Chiba, JP
Keiji Wakita - Midland MI, US
Assignee:
Dow Corning Toray Company, Ltd. - Tokyo
International Classification:
C07F 7/18
C08K 5/00
C08K 5/5465
US Classification:
556413, 556424
Abstract:
A method for producing ketimine structure-containing alkoxysilane comprising reacting amino-functional alkoxysilane with a monocarbonyl compound by heating and azeotropically distilling off the produced water together with the monocarbonyl compound to yield ketimine structure-containing alkoxysilane, characterized by introducing additional monocarbonyl compound at the time of the azeotropic distillation of the produced water together with the monocarbonyl compound.

US Patent:
7932412, Apr 26, 2011
Filed:
Oct 27, 2010
Appl. No.:
12/913705
Inventors:
Keiji Wakita - Midland MI, US
Yasushi Sugiura - Ichihara, JP
Assignee:
Dow Corning Toray Co., Ltd. - Tokyo
International Classification:
C07F 7/10
US Classification:
556409, 556406, 556407
Abstract:
To provide an aminoaryl-containing organosilicon compound with high efficiency, after protecting amino groups of a haloaniline compound with a specific compound, to form a Grignard reagent and to deprotect the aforementioned groups by reacting the Grignard reagent with a silicon compound.

Method Of Manufacturing An Organic Silicon Compound That Contains A Methacryloxy Group Or An Acryloxy Group

View page
US Patent:
8148565, Apr 3, 2012
Filed:
Aug 9, 2006
Appl. No.:
12/064208
Inventors:
Keiji Wakita - Midland MI, US
Assignee:
Dow Corning Toray Company, Ltd. - Chiyoda-ku, Tokyo
International Classification:
C07D 279/18
US Classification:
556436, 556440
Abstract:
A method of manufacturing an organic silicon compound that contains a methacryloxy group or an acryloxy group is characterized by the fact that manufacturing or conducting purification by distillation is carried out in the presence of a phenothiazine derivative having a molecular weight equal to or higher than 240. A stable composition comprises the organic silicon compound that contains a methacryloxy group or an acryloxy group and the phenothiazine derivative having a molecular weight equal to or higher than 240. The phenothiazine derivative is used in an amount sufficient to stabilize the organic silicon compound.

Process For The Preparation Of Haloalkylalkoxysilanes And Haloalkylhalosilanes

View page
US Patent:
8580994, Nov 12, 2013
Filed:
Jan 13, 2009
Appl. No.:
12/867337
Inventors:
Paul Charles Dinh - Midland MI, US
Keiji Wakita - Midland MI, US
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.
