Process For The Manufacture Of Blocked Mercaptosilanes

View page
US Patent:
6777569, Aug 17, 2004
Filed:
Mar 3, 2003
Appl. No.:
10/378184
Inventors:
Mark D. Westmeyer - Marietta OH
Russell Burton - Marietta OH
Tiberiu L. Simandan - Marietta OH
Assignee:
General Electric Company - Pittsfield MA
International Classification:
C07F 704
US Classification:
556429, 556427
Abstract:
A process for the manufacture of a blocked mercaptosilane comprising: reacting at least one polysulfane-containing organosilicon compound of the general formula: (a) in which each R is independently methoxy, ethoxy or alkyl of from 1 to about 6 carbon atoms, provided, that at least one R group is methoxy or ethoxy, G is an alkylene group of from 1 to about 12 carbon atoms and n is from 2 to about 8, with at least one alkali metal, alkaline earth metal or a basic derivative of an alkali metal or alkaline earth metal to provide the corresponding metal salt of the polysulfane-containing organosilicon compound and; (b) reacting the metal salt of the polysulfane-containing organosilicon compound with an acyl halide or carbonyl dihalide to provide a blocked mercaptosilane.

US Patent:
7151188, Dec 19, 2006
Filed:
Nov 16, 2005
Appl. No.:
11/280698
Inventors:
Tiberiu L. Simandan - Marietta OH, US
Michael R. Powell - New Martinsville WV, US
Assignee:
General Electric Company - Schenectady NY
International Classification:
C07F 7/08
US Classification:
556429, 556427
Abstract:
Mercaptoalkylalkoxysilane is obtained by reacting at least one sulfide of the general formulaMHSwherein M is an alkali metal or ammonium with a haloalkyl silane in an aqueous reaction medium in the presence of an acidic gas to maintain the pH of the reaction medium at or below about 10, and in the additional presence of alkylguanidinium salt phase transfer catalyst to provide mercaptoalkylalkoxysilane, the alkylguanidinium salt phase transfer catalyst being represented by the general formula:.

Aqueous Catalytic Process For The Preparation Of Thiocarboxylate Silane

View page
US Patent:
7528273, May 5, 2009
Filed:
Apr 14, 2005
Appl. No.:
11/105916
Inventors:
Tiberiu Ladislau Simandan - Marietta OH, US
Thomas Link Guggenheim - Mt. Vernon IN, US
Assignee:
Momentive Performance Materials Inc. - Albany NY
International Classification:
C07F 7/08
US Classification:
556429
Abstract:
An aqueous process is described in which thiocarboxylate silane is produced from haloalkyl silane by reaction of the haloalkyl silane with an aqueous solution of thiocarboxylate salt in the presence of a catalytically effective amount of alkylguanidinium salt.

Blocked Mercaptosilane Coupling Agents, Process For Making And Uses In Rubber

View page
US Patent:
7781606, Aug 24, 2010
Filed:
Dec 28, 2006
Appl. No.:
11/647780
Inventors:
Richard W. Cruse - Yorktown Heights NY, US
W. Michael York - Concord NC, US
Eric R. Pohl - Mt. Kisco NY, US
Antonio Chaves - Chappaqua NY, US
Tiberiu L. Simandan - Marietta OH, US
Prashant Joshi - Gaithersburg MD, US
Assignee:
Momentive Performance Materials Inc. - Albany NY
International Classification:
C07F 7/04
US Classification:
556429
Abstract:
The invention relates to sulfur silane coupling agents containing multiple blocked mercapto groups which are in a state of reduced activity until activated. The coupling agents are advantageously used in rubber formulations, for example, for fabricating tires with low rolling resistance.

Filed:
May 18, 2007
Appl. No.:
11/750361

International Classification:
C08F 285/00
US Classification:
525478
Abstract:
Bis(aminoalkyl)siloxane dimers or oligomers are prepared by a process utilizing hydrosilation of an olefinic amine with tetraorganodisiloxane or with bis(dialkylhydrogen)siloxane oligomers to generate high purity bis(aminoalkyl)disiloxane or bis(aminoalkyl)siloxane oligomers at high conversion yield, which may then be subsequently equilibrated to higher molecular weight bis(aminoalkyl)polysiloxanes.
