Abstract:

A method is disclosed for producing phosgene which in one embodiment comprises contacting in at least one reactor a mixture comprising carbon monoxide and chlorine sequentially with a first catalyst followed by contacting the resulting gaseous reaction mixture comprising phosgene with at least one second catalyst of higher relative activity than a first catalyst. In another embodiment a method is disclosed for producing phosgene which comprises contacting in at least one reactor a mixture comprising carbon monoxide and chlorine with at least one catalyst bed comprising a first catalyst wherein at least a portion of said first catalyst is diluted with a second catalyst of higher relative activity than a first catalyst.

Appl. No.:

8/172797

Inventors:

Philip G. Kosky - Niskayuna NY
Erik O. Einset - Niskayuna NY
David W. Woodruff - Clifton Park NY

Assignee:

General Electric Company - Schenectady NY

International Classification:

C23C 1600

US Classification:

118924

Abstract:

Temperature uniformity and control in apparatus for chemical vapor deposition of diamond is improved by contacting the rear of the substrate assembly, which may be a substrate or a holder containing substrates, with a thermal spreader, preferably of copper and preferably having heating means embedded therein or associated therewith. The thermal spreader contacts a thermal resistance unit, preferably of stainless steel, which in turn is in contact with a cooling element that preferably has coolant passages therein.

Appl. No.:

8/415119

Inventors:

Philip G. Kosky - Schenectady NY
Thomas R. Anthony - Schenectady NY

Assignee:

General Electric Company - Worthington OH

International Classification:

B29C 3500
C23C 1626

US Classification:

264 81

Abstract:

A method for producing CVD diamond film on a substrate comprised of a hydride-forming metal. The substrate provides for easy release of the CVD diamond coating formed thereon upon exposure to a hydrogen pressure. Self-supporting CVD diamond films of large dimension are easily obtained without dissolving the substrate. The substrate can be used in conventional CVD reactors.

International Classification:

H07M 1050

US Classification:

429120

Abstract:

A battery exposed to heating from incident sunlight is cooled by rejecting heat to air drawn through a chimney by the heating of at least portions of the chimney by the incident sunlight. The battery is placed within the chimney so that the air flow in the chimney passes around the battery, enabling heat to be transferred directly from the battery to the air. Air flow in the chimney is generated by sunlight incident on the exterior of the chimney, causing heating of air within at least a portion of the chimney to create a natural convective air flow within the chimney, with relatively cool outside ambient air being drawn in at one end of the chimney and heated air being exhausted out the other end of the chimney.

Assignee:

General Electric Company - Schenectady NY

International Classification:

C07C 6802
C07C 6996

US Classification:

558265

Abstract:

A method is provided for reducing the reflux temperatures of methylene chloride in phosgenation reactions by introducing a second inert vaporizable component to the reaction medium. This second inert vaporizable component has a lower vaporization temperature than the methylene chloride so as to reduce the temperature of vaporization of the mixture. More efficient use of phosgene is obtained when polymerizing aromatic dihydroxy compounds to polycarbonates and higher yields of monomeric and dimeric bischloroformates are obtained.

Assignee:

General Electric Company - Schenectady NY

International Classification:

C07C 6800

US Classification:

558281

Abstract:

A method is provided for making reaction products of phosgene and dihydric phenol under interfacial reaction conditions. The dihydric phenol such as BPA is introduced into the reactor in the form of a stable suspension which reduces phosgene hydrolysis, minimizes phosgene escape and effects improved BPA metering into the reactor.
