摘要:Disclosed is a method of making and using a titania supported palladium catalyst for the single step synthesis of 2-ethylhexanal from a feed of n-butyraldehyde. This titania supported palladium catalyst demonstrates high n-butyraldehyde conversion but also produces 2-ethylhexanal in an appreciable yield with maintained activity between runs. This method provides a single step synthesis of 2-ethylhexanal from n-butyraldehyde with a catalyst that can be regenerated that provides cleaner downstream separations relative to the traditional caustic route.

标 题:Manufacture of α-formylethanephosphonic acid esters
发明人：SCHREPFER HANS J; SIEGEL HARDO; THEOBALD HANS
权利人:BASF AG
摘要:α-Formylethane-phosphonic acid esters are manufactured by reacting vinylphosphonic acid esters with carbon monoxide and hydrogen in the presence of conventional rhodium-containing hydroformylation catalysts. The reaction is carried out at from 50° to 180° C. and at pressures from 20 to 1,500 bars. The products are intermediates for the synthesis of insecticidally active phosphoric acid ester derivatives.

权利人:HOECHST AG
摘要:For the preparation of predominantly unbranched higher primary alcohols, olefins from the Fischer-Tropsch synthesis are reacted with hydrogen and carbon monoxide in the presence of water and a catalyst which is rhodium, in metallic form or as a compound, and a water-soluble phosphine. The reaction product obtained is hydrogenated. The water-soluble phosphines employed are compounds whose anion is a phosphine containing at least one sulfonated or carboxylated aromatic radical and whose cation is a quaternary ammonium or phosphonium ion.

权利人:UNION OIL CO
摘要:HYDRIDE CARBONYL COMPLEXES OF RHODIUM AND IRIDIUM WITH BIPHYLIC LIGANDS ARE PREPARED BY TREATMENT OF RHODIUM OR IRIDIUM, COMPLEXES OR SALTS THEREOF WITH AN ALKALI METAL HYDROXIDE, ALKOXIDE OR ARYLOXIDE AND A BIPHYLLIC LIGAND AND A MIDL REDUCING AGENT. IN A TYPICAL SYNTHESIS A RHODIUM CARBONYL SALT IS CONTACTED WITH AN ALKALI METAL ALKOXIDE IN THE PRESENCE OF THE LIGAND AND THE HYDRIDE IS FORMED BY SUBSEQUENT OR SIMULTANEOUS CONTACTING WITH A REDUCING AGENT SUCH AS HYDROGEN, CARBON MONOXIDE OR AN OXIDIZABLE ALCOHOL. THE COMPOUNDS HAVE UTILITY AS HYDROFORMYLATION CATALYSTS.

摘要:A process for the preparation of aldehydes or aldehydes and alcohols by hydroformylation of olefins containing more than 3 carbon atoms, comprising a hydroformylation stage, in which the olefin is hydroformylated under a pressure of form 50 to 1000 bar and at a temperature of from 50° to 180° C. by means of a rhodium catalyst dissolved in a homogenous reaction medium and a catalyst recovery stage comprising extraction of the rhodium catalyst with an aqueous solution of chelating agent, isolation of alcohols and/or aldehyde from the extracted hydroformylation product steam, precarbonylation of the aqueous rhodium-containing extract in the presence of carbon monoxide, synthesis gas as, or a gas mixture containing carbon monoxide under a pressure of from 50 to 1000 bar and at a temperature of from 50° to 180° C., separation of the effluent of the precarbonylation stage into an organic phase containing the major portion of the rhodium and an aqueous phase containing the chelating agent and recycling of the organic phase to the hydroformylation stage, where the rhodium catalyst is extracted from the effluent of the hydroformylation stage using an aqueous solution of a sulfonic acid group-free, water-soluble polymer capable of chelating rhodium.
