Catalytic reduction of organic carbonyls using metal catalysts: Patented by Stephen L. Buchwald, Alberto Gutierrez, Scott C. Berk and Kristina A. Kreutzer on November 4, 1991. Abstract: A process is provided whereby organic carbonyl substrates, including esters, lactones, ketones, amides and imides are reduced in a reaction with a silane reducing reagent and a catalyst. Exemplary catalysts include metal alkoxides and metal aryloxides.
Cyclic hydrazine compounds: Patented by Guido Bold, Shripad S. Bhagwat, Alexander Fassler and Marc Lang on January 1, 1996. Abstract: This invention relates to substituted cyclic carbonyls and derivatives thereof useful as retroviral protease inhibitors to pharmaceutical compositions comprising such compounds, and to methods of using these compounds for treating vital infection.
Detection of hydrolyzing enzymes: Patented by Jon N. Eikenberry, Karen L. Warren, Brooke P. Schlegel and Dolores L. Humbert on January 1, 1986. Abstract: A composition of a polysaccharide with a detectable material appended thereto and a 1,3-dione having a methylene group between the two carbonyls of the 1,3-dione, which methylene group has at least one ionizable hydrogen, provides accurate results in assays of hydrolyzing enzymes such as amylase. The composition can be incorporated in the reagent zone of a dry test element having a reagent zone and a registration zone.
Efficient synthesis of alkyl carbonates: Patented by Kyung Woon Jung on February 5, 2000. Abstract: Efficient synthetic methods towards mixed aliphatic carbonates through the three component couplings of aliphatic alcohols, alkyl halides and carbon dioxide in the presence of cesium carbonate and tetrabutylammonium iode (TBAI). Due to their enhanced nucleophilicities, cesium alkoxides are smoothly incorporated into CO.sub.2, allowing for mild reaction conditions such as ambient temperatures and short reaction durations. Various primary and secondary substrates are compatible under the standard conditions, offering high yields, while chiral templates such as .alpha.-hydroxy carbonyls are resistant to racemization.
Formaldehyde resistant catalyst for hydrogenation and hydrogenolysis of aldehydes, acetals, and esters: Patented by Jerry A. Broussard on March 8, 1990. Abstract: Rhenium has been found to be formaldehyde resistant catalyst and is thus useful in the catalytic hydrogenation of carbonyls, acetals and esters to alcohols when the reaction medium contains formaldehyde as a reactant or impurity. Also, rhenium is a useful catalyst in the hydrogenolysis of acylic acetals to alcohols.
Method for regenerating a loaded wash liquid from a gas desulfurization facility: Patented by Gerhard Grunewald and Uwe Zwiefelhofer on December 6, 1999. Abstract: Process for the removal of metal cabonyls before regeneration of a desulfurization wash liquid, which includes removing a part of the carbon monoxide from the wash liquid, conversion of the metal carbonyls to metal sulfides, passing the wash liquid through a reaction and settling zone, removing metal sulfide-containing sludge from the reaction and settling zone, and regenerating the wash liquid.
Method of water control with hydroxy unsaturated carbonyls: Patented by Klein A. Rodrigues on October 2, 1993. Abstract: A method of forming a gel in the subsurface formation is provided whereby a self crosslinking monomer selected from hydroxy unsaturated carbonyl compounds is polymerized in the formation by a suitable initiator. In a preferred embodiment, the initiator is selected from ago compounds which are temperature activated over a range of temperatures. The method is particularly useful to substantially terminate or at least decrease the flow of water from a subterranean formation into a wellbore penetrating the formation .
POLYIMIDE RESINS FROM BIS-IMIDE, MONOMER HAVING TWO METHYLENE GROUPS ACTIVATED BY ADJACENT CARBONYLS, AND POLYAMINE: Patented by Alfred J. Restaino on February 1, 1989. Abstract: Polyimide addition copolymers of improved physical properties and thermal stability are prepared by reacting ethylenically unsaturated bis-imides with compounds having two methylene groups activated by adjacent carbonyl groups. The copolymers may be made in the presence of catalytic amounts of amines or with greater amounts of polyamines. The polymers are useful in producing molding powders, prepregs, laminates, circuit boards, encapsulants and metal clad shapes.
Process and apparatus for removing carbonyls and moisture from a gas: Patented by James T. Snow on November 8, 1998. Abstract: A process and composition for removing metal carbonyls and moisture from a gas wherein the gas is contacted with a metal oxide, an organometallic oxide or mixtures thereof having a reduction potential greater than about 0.175 volts and a composition capable of removing moisture from the gas.
Process for producing MMT: Patented by Carl O. Inabinet, Fred H. Gregory, David M. Marchand and Robert B. Agee on June 4, 1992. Abstract: A process for the carbonylation of substituted metal coordination compounds in the presence of carbon monoxide at a pressure in excess of 400 psig to produce optionally substituted cyclopentadienyl metallic carbonyls, particularly methylcyclopentadienyl manganese tricarbonyl in a thin-film-producing reactor.
