Patent application numberDescriptionPublished
20080207958Method For Production Of 1,6-Hexanediol With A Purity In Excess of 99.5% - The present invention provides a process for preparing 1,6-hexanediol by hydrogenating dialkyl adipates, alkyl 6-hydroxycaproates, 1,4-cyclohexanedione and 4-hydroxycyclohexan-1-one as ester mixtures comprising impurities, by 08-28-2008
20080216390Biodiesel Fuel Mixture Containing Polyoxymethylene Dialkyl Ether - A biodiesel fuel mixture having a cetane number of >40, comprising 09-11-2008
20080217158Method for Obtaining Cyclododecatriene by Evaporation - Process for recovering cyclododecatriene (CDT) from a solution comprising CDT and high boilers such as deactivated catalyst and polymers, which comprises feeding the solution into a preheater and heating it, subsequently depressurizing it through a downstream pressure maintenance device and feeding the resulting two-phase mixture into a helical tube evaporator and there reducing the CDT content of the liquid phase by partial evaporation and discharging a gaseous product stream having an increased concentration of CDT.09-11-2008
20080299390Moulded Catalyst Bodies and Method for Hydrogenation of Carbonyl Compounds - The invention relates to a method for hydrogenation of an organic compound comprising at least one carbonyl group, whereby the organic compound is brought into contact with a moulded body in the presence of hydrogen. Said body may be produced by a method in which (i) an oxidic material is prepared, comprising copper oxide, aluminium oxide, and at least one oxide of lanthanum, tungsten, molybdenum, titanium, or zirconium, followed by (ii) addition of powdered metallic copper, copper platelets, powdered cement, graphite, mixtures or a mixture thereof with graphite to the oxidic material and (iii) moulding the mixture from (ii) to give a moulded body, characterised in that the moulded body is in the form of catalyst tablets or catalyst extrudates with a diameter d and/or height h<2.5 mm, catalyst beads with a diameter d<2.5 mm or catalyst honeycomb with a cell diameter r12-04-2008
20090043102METHOD FOR PRODUCING HETEROAROMATIC ALCOHOLS - A process for preparing heteroaromatic alcohols by catalytically hydrogenating heteroaromatic carboxylic acids or esters thereof by hydrogenating with hydrogen in the presence of a ruthenium-phosphine complex in an organic solvent.02-12-2009
20090247779METHOD FOR PRODUCING 3-PENTENENITRILE BY MEANS OF THE HYDROCYANATION OF 1,3-BUTADIENE - A method for producing 3-pentenenitrile by means of the hydrocyanation of 1,3-butadiene, which comprises the following process steps: 10-01-2009
20100056364CATALYST AND PROCESS FOR HYDROGENATING CARBONYL COMPOUNDS - A process for hydrogenating an organic compound which has at least one carbonyl group, in which the organic compound is hydrogenated in the presence of a shaped article which contains (i) an oxidic material comprising copper oxide, aluminum oxide and lanthanum oxide, and (ii) powdered metallic copper, copper flakes, powdered cement, graphite or a mixture thereof, is provided.03-04-2010
