| 20090082562 | PROCESS FOR PREPARING AN AMINE - A process for preparing an amine by reacting an aldehyde and/or ketone with hydrogen and a nitrogen compound selected from the group of primary and secondary amines in the presence of a heterogeneous catalyst, wherein the catalyst is a coated catalyst which comprises at least one metal of group VIII of the Periodic Table of the Elements as a hydrogenating metal and additionally a promoter on an oxidic support, at least 80% of the metal of group VIII of the Periodic Table of the Elements being present in a layer between the surface of the catalyst and a penetration depth which is not more than 80% of the radius of the catalyst, calculated from the surface of the catalyst. | 03-26-2009 |
| 20090093654 | METHOD OF PRODUCING BENZOPHENONEIMINES - A process for the preparation of benzophenonimine (BPI) of the general formula I | 04-09-2009 |
| 20100081804 | PROCESS FOR CONTINUOUS HYDROGENATION OR HYDROGENATING AMINATION - A process is described for continuously hydrogenating unsaturated compounds, in which particles of a first hydrogenation catalyst are suspended in a liquid phase in which an unsaturated compound is dissolved, the liquid phase, in the presence of a hydrogenous gas at a first partial hydrogen pressure and at a first temperature, is conducted through a packed bubble column reactor in cocurrent counter to the direction of gravity, the effluent from the bubble column reactor is sent to a gas-liquid separation, the liquid phase is sent to a crossfiltration to obtain a retentate and a filtrate, the retentate is recycled into the bubble column reactor and the filtrate, in the presence of a hydrogenous gas at a second partial hydrogen pressure and at a second temperature, is passed over a bed of a second hydrogenation catalyst, wherein the second partial hydrogen pressure is at least 10 bar higher than the first partial hydrogen pressure. | 04-01-2010 |
| 20100267948 | PROCESS FOR THE PREPARATION OF AN AMINE - Process for preparing an amine by reacting an aldehyde and/or ketone with hydrogen and a nitrogen compound selected from the group consisting of primary and secondary amines in the presence of a heterogeneous catalyst, wherein the reaction is carried out using a suspended catalyst as heterogeneous catalyst and is carried out in the semibatch mode in which the nitrogen compound as one reactant is placed in the reaction vessel and the aldehyde and/or the ketone as the other reactant is added during the course of the reaction and the aldehyde and/or the ketone is added in portions or continuously to the reaction mixture during the course of the reaction as a function of the achieved conversion of the nitrogen compound until a conversion of the nitrogen compound of at least 95% results, and all or part of the catalyst remains in the reaction vessel after the reaction batch and is reused for the next reaction batch. | 10-21-2010 |
