权利人:UNIV DORTMUND TECH
摘要:A method for the synthesis of a chimeric conjugate molecule by micellar catalysis that may form part of DNA-encoded compound libraries. A DNA-coupled organic starter molecule may be reacted with another organic compound, using a catalyst located within a micelle, to form a conjugate of an organic candidate compound coupled to a DNA identifier tag.

标题 :Process for the synthesis of ethanol and acetaldehyde using cobalt compounds with novel promoters
发明人：LIN JIANG-JEN; KNIFTON JOHN F
权利人:TEXACO INC
摘要:Ethanol and/or acetaldehyde are prepared in good yield by contacting methanol, hydrogen and carbon monoxide with a catalyst system comprising a cobalt-containing compound and a promoter in the presence of an inert oxygenated solvent at a temperature of from about 50 DEG C. to about 350 DEG C. and a pressure of at least 500 psig or greater. The combination of cobalt-containing compound and promoter may be (a) a cobalt-containing compound with an organo-sulphur compound, (b) an iodide-containing cobalt compound with a nitrogen-containing compound as promoter, and (c) a cobalt-containing compound with 1,1'-bis(diphenylphosphino)ferrocene.

标 题:Synthesis of aldehydes from alcohols
发明人：WEGMAN RICHARD W; MILLER DEBORAH S
权利人:UNION CARBIDE CORP
摘要:A catalyst has been found for the low pressure hydroformylation of alcohols to produce aldehydes. This catalyst consists of a rhodium containing compound, an iodide containing compound, and a chelating Group V compound, which is used alone or in combination with a monodentate, Group V compound. n It is the first rhodium-based catalyst that generates acetaldehyde via hydroformylation of the methanol. The reaction is typically carried out at 160°-180° C. and 1000-2000 psi. The acetaldehyde rate and selectivity are 1-5 Mhr -1 and 50-75%. Conventional cobalt catalysts require operating pressures of at least 3000-6000 psi in order to obtain reasonable productivities.

标题:Alcohols prepared from olefins and synthesis gas
发明人：KNIFTON JOHN F
权利人:TEXACO INC
摘要:This invention concerns a process of preparing predominantly linear alcohols which comprises the steps of contacting a mixture of terminal and/or internal olefins and synthesis gas with a catalyst system comprising a ruthenium-containing compound coupled with one or more bidentate or multidentate, phosphine-containing promoters, dispersed in a low melting quaternary phosphonium salt, and heating said resultant reaction mixture under a pressure of 100 psi or greater at a temperature of at least 50 DEG C. for a sufficient time to produce said alcohols.
