    Abstract: 40Method for producing formic acid Abstract5 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 and a tertiary amine (1) in a molar ratio of from 0.5 to 5 is produced by combining tertiary amine (I) and a formic acid source, from 10 to 100% by weight of the secondary components present therein are separated off and formic acid is removed by distillation in a distillation apparatus at a bottom temperature of from10 100 to 300°C and a pressure of from 30 to 3000 hPa abs from the liquid stream obtained, the bottom discharge from the distillation apparatus being separated into two liquid phases and the upper liquid phase being recycled to the formic acid source and the lower liquid phase being recycled for separating off the secondary components and/or to the distillation apparatus.

    Abstract: Process for preparing formic acid by reaction of carbon dioxide with hydrogen Abstract 5 A process for preparing formic acid by reaction of carbon dioxide (1) with hydrogen (2)in a hydrogenation reactor (I) in the presence ofa catalyst comprising an element of group 8, 9 or 10 of the Periodic Table, a tertiary amine comprising at least 12 carbon atoms per molecule and 10 a polar solvent comprising one or more monoalcohols selected from among methanol, ethanol, propanols and butanols and also water,to form formic acid/amine adducts as intermediates which are subsequently thermally dissociated, with work-up of the output (3) from the hydrogenation reactor (I) in a 15 plurality of process steps, wherea tertiary amine-comprising stream (13) from the work-up is used as selective solvent for the catalyst, is proposed.20(Figure 1)

    Abstract: Method for producing formic acid AbstractProcess for prepering formic acid by hydrogenation of carbondioxide in the presence of a catalyst comprising an element of group 8, 9 or 10 of the Periodic Table, a teritary amine and a polar solvent at a pressure of from 0,2 to 30 MPs abs and a temperature of from 20 to 200°C to form two liquid phases, separation of the two liquid phases, wherein the liquid phase (B) enriched with the tertiary amine is recirculated to the 10 hydrogenation reactor and the formic aciduct from the liquid phase (A) enriched with the formic acid/amine adduct and the polar solvent is thermally dissociated into free formic add and free tertiary amine in a distillation unit and the tertiary amine liberated in the dissociation and the polar solvent are recirculated to the hydrogenation reactor.

    Abstract: PROCESS FOR PREPARING FORMIC ACID BY HYDROGENATION OF CARBON DIOXIDE 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 AT A PRESSURE OF FROM 0.2 TO 30 MPA ABS AND A TEMPERATURE OF FROM 20 TO 200° C. TO FORM TWO LIQUID PHASES, SEPARATION OF THE TWO LIQUID PHASES, WHEREIN THE LIQUID PHASE (B) ENRICHED WITH THE TERTIARY AMINE IS RECIRCULATED TO THE HYDROGENATION REACTOR (A) AND THE FORMIC ACID/AMINE ADDUCT FROM THE LIQUID PHASE (A) ENRICHED WITH THE FORMIC ACID/AMINE ADDUCT AND THE POLAR SOLVENT IS THERMALLY DISSOCIATED INTO FREE FORMIC ACID AND FREE TERTIARY AMINE IN A DISTILLATION UNIT (C) AND THE TERTIARY AMINE LIBERATED IN THE DISSOCIATION AND THE POLAR SOLVENT ARE RECIRCULATED TO THE HYDROGENATION REACTOR (A).
