    Abstract: The invention relates to a method for producing formic acid by reacting carbon dioxide (1) with hydrogen (2) in a hydrating reactor (I) in the presence of a catalyst comprising an element from the 8th, 9th, or 10th group of the periodic system; a tertiary amine containing at least twelve carbon atoms per molecule; and a polar solvent comprising one or more monoalcohols selected from methanol, ethanol, propanols, and butanols, forming formic acid / amine adducts as intermediate products, which are subsequently thermally split, wherein a tertiary amine having a boiling point at least 5°C higher than formic acid is used, and wherein a reaction mixture comprising the polar solvent, the formic acid / amine adducts, the tertiary amine, and the catalyst forms from the reaction in the hydrating reactor (I) and is discharged as a discharge (3) from the reactor.

    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: 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 tertiary amine (I) is produced by combining tertiary amine (I) and a formic acid source, secondary components comprised therein are separated off, formic acid is removed by distillation from the resulting liquid stream in a distillation apparatus, where the bottom output from the distillation apparatus is separated into two liquid phases, and the upper liquid phase is recirculated to the formic acid source and the lower liquid phase is recirculated to the separation of the secondary components and/or to the distillation apparatus, wherein low boilers are removed by distillation from the upper liquid phase and recirculated to the depleted stream.
