Abstract: The invention relates to a method for obtaining formic acid by thermally separating a flow containing formic acid and a tertiary amine (I), wherein a liquid flow containing formic acid, tertiary amine (I), and water is produced by bringing together a 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 from the obtained liquid flow by means of distillation in a distillation device, wherein the removed flow containing water and organic decomposition products of the tertiary amine (I) is separated into two liquid phases, the upper liquid phase is removed, and the lower liquid phase containing water is fed back to the formic acid source.

IPC: C07C20060101
Abstract: The invention relates to a method for producing formic acid by hydrogenation of carbon dioxide in the presence of a catalyst which contains an element of the 8th, 9th or 10th group of the periodic system, a tertiary amine and a polar solvent, at a pressure of 0.2 to 30 MPa abs and a temperature of 20 to 200°C, thereby producing two liquid phases, and separation of the two liquid phases. The liquid phase (B) enriched by the tertiary amine is returned to the hydrogenation reactor and the formic acid/amine addition product from the liquid phase (A) enriched by the formic acid/amine addition product and the polar solvent is thermally separated into free formic acid and free tertiary amine in a distillation unit and the tertiary amine released during separation and the polar solvent are returned to the hydrogenation reactor.

Abstract: A process is proposed for preparing formic acid by reaction of carbon dioxide (1) with hydrogen (2) in a hydrogenation reactor (I) in the presence of a catalyst containing an element from group 8, 9 or 10 of the Periodic Table, of a tertiary amine containing at least 12 carbon atoms per molecule, and of a polar solvent comprising one or more monoalcohols selected from methanol, ethanol, propanols and butanols, to form formic acid/amine adducts as intermediates, which are subsequently cleaved thermally, the workup of the outputs (3) from the hydrogenation reactor (I) being performed with addition of water, and this increasing the partition coefficient of the catalyst between the upper phase (4) and the lower phase.

Abstract: The invention relates to a method for obtaining formic acid by the thermal separation of a flow containing formic acid and a tertiary amine (I), wherein a liquid flow which contains formic acid and a tertiary amine (I) in a molar ratio of 0.5 to 5 is produced by combining tertiary amine (I) and a source of formic acid, 10 to 100 wt % of the secondary components contained in said flow are separated, and formic acid is removed by distillation from the resulting liquid flow in a distillation device at a bottoms temperature of 100 to 300°C and a pressure of 30 to 3000 hPa abs, wherein the bottoms product from the distillation device is separated into two liquid phases and the upper liquid phase is returned to the source of formic acid and the lower liquid phase is returned for separation of the secondary components and/or to the distillation device.
