专利号:US-9096519-B2 优先权日:2013-01-10 标 题 :Process for the synthesis of ketones from internal alkenes 发明人:MORANDI BILL; GRUBBS ROBERT H; WICKENS ZACHARY K; LERCH MICHAEL M 权利人:CALIFORNIA INST OF TECHN 摘要:The present invention is directed to methods for oxidizing internal olefins to ketones. In various embodiments, each method comprising contacting an organic substrate, having an initial internal olefin, with a mixture of (a) a biscationic palladium salt; and (b) an oxidizing agent; dissolved or dispersed in a solvent system to form a reaction mixture, said solvent system comprising at least one C 2-6 carbon nitrile and optionally at least one secondary alkyl amide, said method conducted under conditions sufficient to convert at least 50 mol % of the initial internal olefin to a ketone, said ketone positioned on a carbon of the initial internal olefin. The transformation occurs at room temperature and shows wide substrate scope. Applications to the oxidation of seed oil derivatives and a bioactive natural product are described.

专利号:US-8350108-B2 优先权日:2008-08-27 标题 :Synthesis of liquid fuels from biomass 发明人:CORTRIGHT RANDY D; BLOMMEL PAUL G; WERNER MICHAEL J; VANSTRATEN MATTHEW R 权利人:VIRENT INC; CORTRIGHT RANDY D; BLOMMEL PAUL G; WERNER MICHAEL J; VANSTRATEN MATTHEW R 摘要:Processes and reactor systems are provided for the conversion of oxygenated hydrocarbons to paraffins useful as liquid fuels. The process involves the conversion of water soluble oxygenated hydrocarbons to oxygenates, such as alcohols, furans, ketones, aldehydes, carboxylic acids, diols, triols, and/or other polyols, followed by the subsequent conversion of the oxygenates to paraffins by dehydration and alkylation. The oxygenated hydrocarbons may originate from any source, but are preferably derived from biomass.

专利号:US-2024010585-A1 优先权日:2020-11-27 标 题 :Reduction by a silane in the presence of zinc catalyst 发明人:JERPHAGNON THOMAS; PASTORI JOEL 权利人:FIRMENICH & CIE 摘要:The present invention relates to the field of organic synthesis. More specifically, it concerns a process for the selective reduction of a C 3 -C 70 substrate containing one or more carbonyl or carboxylic functional groups into the corresponding 5 alcohol diol, or polyalcohol in the presence of a silane and at least one catalyst or pre-catalyst in the form of a zinc complex. The Zinc complex of formula (I) or (II) is also part of the invention.
专利号:US-7311815-B2 优先权日:2003-02-20 标题 :Hydrocarbon products and methods of preparing hydrocarbon products 发明人:ABAZAJIAN ARMEN N 权利人:SYNTROLEUM CORP 摘要:A method of preparing high linear paraffin or high end-chain monomethyl content products is accomplished by converting synthesis gas in a Fischer-Tropsch reaction to hydrocarbon products. These may be hydrotreated to provide an n-paraffin content of greater than 50% by weight, with substantially all branched paraffins being monomethyl end-chain branched paraffins. At least one non-linear paraffin isomer, which may be a monomethyl paraffin isomer, may be separated from the hydrocarbon products through distillation to provide an n-paraffin product having an n-paraffin content percentage by weight of the n-paraffin product that is greater than the initial n-paraffin content.
