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 DEG 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.
