Patent application numberDescriptionPublished
20110060166METHOD FOR PRODUCING N,N-SUBSTITUTED-1,3-PROPANDIAMINES - The present invention relates to a process for preparing N,N-substituted 1,3-propanediamine by 03-10-2011
20110251433PROCESS FOR PREPARING UNSYMMETRIC SECONDARY TERT-BUTYLAMINES IN THE LIQUID PHASE - The present application relates to a process for preparing unsymmetric secondary tert-butylamines which, as well as the tert-butyl radical, also comprise an alkyl, cycloalkyl or benzyl radical. They are prepared by reacting corresponding aldehydes with tert-butylamine and hydrogen in the presence of hydrogenation catalysts (reductive amination) in the liquid phase.10-13-2011
20110251434PROCESS FOR PREPARING UNSYMMETRIC SECONDARY TERT-BUTYLAMINES IN THE GAS PHASE - The present invention relates to a process for preparing unsymmetric secondary tert-butylamines by continuous amination in the gas phase, wherein tert-butylamine is converted over hydrogenation catalysts in the presence of an alcohol or aldehyde and hydrogen.10-13-2011
20110288338METHOD FOR PRODUCING N,N-SUBSTITUTED-3-AMINOPROPAN-1-OLS - The present invention relates to a process for preparing N,N-substituted 3-aminopropan-1-ols by 11-24-2011
20110313186HYDROGENATION CATALYSTS, THE PRODUCTION AND THE USE THEREOF - The present invention relates to catalysts and processes for preparation thereof, said catalysts being obtainable by contacting a monolithic catalyst support with a suspension which comprises one or more insoluble or sparingly soluble compounds of the elements selected from the group of the elements cobalt, nickel and copper. The invention further relates to the use of the inventive catalyst in a process for hydrogenating organic substances, especially for hydrogenating nitriles, and to a process for hydrogenating organic compounds, which comprises using an inventive catalyst in the process.12-22-2011
20110313187METHOD FOR IMPROVING THE CATALYTIC ACTIVITY OF MONOLITHIC CATALYSTS - The present invention relates to a process for improving the catalytic properties of a catalyst comprising one or more elements selected from the group consisting of cobalt, nickel and copper, said catalyst being present in the form of a structured monolith, by contacting the catalyst with one or more basic compounds selected from the group of the alkali metals, alkaline earth metals and rare earth metals. The invention further relates to a process for hydrogenating compounds which comprise at least one unsaturated carbon-carbon, carbon-nitrogen or carbon-oxygen bond in the presence of a catalyst comprising one or more elements selected from the group consisting of cobalt, nickel and copper, said catalyst being present in the form of a structured monolith, by contacting the catalyst with one or more basic compounds selected from the group of the alkali metals, alkaline earth metals and rare earth metals. The present invention also relates to the use of a basic compound selected from the group of the alkali metals, alkaline earth metals and rare earth metals for improving the catalytic properties of a catalyst comprising cobalt and/or copper and/or nickel, said catalyst being present in the form of a structured monolith.12-22-2011
20110313188METHOD FOR IMPROVING THE CATALYTIC ACTIVITY OF MONOLITHIC CATALYSTS - The present invention relates to a catalyst comprising one or more elements selected from the group consisting of cobalt, nickel and copper, said catalyst being present in the form of a structured monolith, wherein said catalyst comprises one or more elements selected from the group of the alkali metals, alkaline earth metals and rare earth metals. The invention further relates to processes for preparing the inventive catalyst and to the use of the inventive catalyst in a process for hydrogenating organic substances, especially for hydrogenating nitriles.12-22-2011
20120010431METHOD FOR PRODUCING 1-ADAMANTYL TRIMETHYLAMMONIUM HYDROXIDE - The present invention relates to a process for preparing 1-adamantyltrimethyl-ammonium hydroxide.01-12-2012
