Assignee:

Lyondell Chemical Technology, L.P. - Greenville DE

International Classification:

C07D 301/06
C07D 301/12

US Classification:

549533, 549531

Abstract:

The invention is a process for epoxidizing an olefin with hydrogen and oxygen in the presence of a catalyst comprising a noble metal and a titanium or vanadium zeolite in a solvent mixture comprising water, methanol, and a C–Caliphatic ketone. This process surprisingly gives significantly reduced by-product glycol and glycol ethers formed by the unwanted ring-opening of epoxides.

Appl. No.:

11/551324

Inventors:

Robert W. Cochran - Lakeland FL, US

Assignee:

Earthlinked Technologies, Inc. - Lakeland FL

International Classification:

F25B 41/04
F25B 41/00

US Classification:

62222, 62225, 62210

Abstract:

A subcool flow control valve useful in a refrigerant system includes an enclosure having a fluid flow pathway for a controlled fluid between an inlet and an outlet. A thermally conductive flexible wall forms a sealed cavity within the enclosure for carrying a controlling fluid. A metering orifice operable between the pathway and the outlet port controls an amount of metered fluid passing through the outlet port in response to movement of the flexible wall toward and away from the metering orifice in response to temperature changes of the controlled fluid transmitting temperature and thus pressure changes to the controlling fluid in the sealed cavity. Inverse thermal feedback means is formed as part of the valve for stabilizing valve operation thus providing means for transmitting a thermal signal from the metered controlled fluid back to the controlling fluid.

US Classification:

549531, 549532, 549533, 502 66

Abstract:

A catalyst, useful for the direct epoxidation of olefins, is disclosed. The catalyst comprises palladium nanoparticles, support nanoparticles, and a titanium zeolite having a particle size of 2 microns or greater. The palladium nanoparticles are deposited on the support nanoparticles to form supported palladium nanoparticles, and the supported palladium nanoparticles are deposited on the titanium zeolite; or the supported palladium nanoparticles are deposited on a carrier having a particle size of 2 microns or greater. The invention also includes a process for producing an epoxide comprising reacting an olefin, hydrogen and oxygen in the presence of the catalyst. The catalysts are more active in epoxidation reactions, while demonstrating the same or better selectivity.
