20110087038 | PROCESS AND DEVICE FOR THE OXIDATION OF ORGANIC COMPOUNDS - The invention relates to a process for the oxidation of organic compounds by means of oxygen, in which, in a first step, the organic compound and at least part of the oxygen required for the oxidation are introduced into a first reaction zone which is operated isothermally and with backmixing and, in a second step, the reaction mixture from the first reaction zone is introduced into a second reaction zone which is operated adiabatically. The invention further relates to a reactor for carrying out the process, which comprises at least one isothermal reaction zone ( | 04-14-2011 |
20110137077 | PROCESS AND APPARATUS FOR OXIDIZING ORGANIC COMPOUNDS - The invention relates to a process for oxidizing at least one organic substance with oxygen, which comprises the following steps:

20130012739 | PROCESS FOR PREPARING FORMIC ACID BY REACTING CARBON DIOXIDE WITH HYDROGEN - A process for preparing formic acid by reacting carbon dioxide with hydrogen in a hydrogenation reactor in the presence of a catalyst comprising an element of group 8, 9 or 10 of the Periodic Table, a tertiary amine and a polar solvent to form formic acid-amine adducts which are subsequently dissociated thermally into formic acid and tertiary amine. | 01-10-2013 |
20130190532 | PROCESS FOR PREPARING FORMIC ACID - Process for obtaining formic acid by thermal separation of a stream comprising formic acid and a tertiary amine (I), in which a liquid stream comprising formic acid, tertiary amine (I) and water is produced by combining tertiary amine (I) and a formic acid source in the presence of water, water and organic decomposition products of the tertiary amine (I) are removed and formic acid is removed by distillation from the resulting liquid stream in a distillation apparatus, wherein the stream comprising water and organic decomposition products of the tertiary amine (I) which have been separated off is separated into two liquid phases, the upper liquid phase is removed and the lower, water-comprising liquid phase is recirculated to the formic acid source. | 07-25-2013 |
