摘要: Disclosed are a nitrogen-doped hierarchical-porous carbon-loaded nano-Pd catalyst and a preparation method thereof. The preparation method includes preparing nitrogen-doped hierarchical-porous carbon, mixing the nitrogen-doped hierarchical-porous carbon with water, adjusting a pH value of the mixed solution to be alkaline, mixing the mixed solution with a Pd metal precursor aqueous solution, and then adding a reducing agent to obtain the nitrogen-doped hierarchical-porous carbon-loaded nano-Pd catalyst after reduction. The prepared nitrogen-doped hierarchical-porous carbon-loaded nano-Pd catalyst includes a nitrogen-doped porous carbon material carrier with hierarchical pores and Pd metal nanoparticles loaded in the hierarchical pores of the carrier. The Pd metal nanoparticles have a size of 2˜14 nm and a regular polyhedron shape. The nitrogen-doped hierarchical-porous carbon-loaded nano-Pd catalyst has excellent catalytic performance, especially has ultra-high conversion rate, selectivity and cycle stability in the selective hydrogenation reaction of unsaturated ketones, and is a key to open a new synthetic route of vitamin E.

摘要: The present invention relates generally to processes for producing aldehydes wherein an olefinic compound, carbon monoxide, and hydrogen are reacted in the presence of a solubilized rhodium-phosphorous complex. In one embodiment, the process comprises (a) receiving a vaporized aldehyde product stream downstream from a hydroformylation reactor, the vaporized aldehyde product stream comprising aldehydes, phosphorous ligand, and aldehyde condensation by-products; (b) contacting the vaporized aldehyde product stream with a partial condenser so as to condense the phosphorous ligand and the by-products, wherein up to 10 weight percent of the vaporized stream is condensed; (c) removing the condensed phosphorous ligand and the condensed by-products from the liquid condensation stream using a refining column; and (d) further processing the vaporized aldehydes from the separate refining column.

摘要: This document describes biochemical pathways for producing 5-hydroxypentanoate methyl ester and pentanoic acid pentyl ester using one or more of a fatty acid O-methyltransferase, an alcohol O-acetyltransferase, and a monooxygenase, as well as recombinant hosts expressing one or more of such exogenous enzymes. 5-hydroxypentanoate methyl esters and pentanoic acid pentyl esters can be enzymatically converted to glutaric acid, 5-aminopentanoate, 5-hydroxypentanoate, cadaverine, or 1,5-pentanediol.

摘要: Mixed butene streams containing butene-1 and isobutylene and optionally butene-2 are hydroformylated under conditions that hydroformylates all the monomers to yield a mixture of valeraldehydes. Higher temperatures and/or longer residence times and/or higher partial pressure of carbon monoxide than in conventional processes are used to ensure hydroformylation of all the monomers.
