Abstract: The invention relates to a method for producing formic acid by generating the corresponding ammonium formate by means of catalytic hydrogenation of c arbon dioxide with hydrogen on a catalyst comprising a metal of groups 8 thr ough 10 of the periodic system, in the presence of a primary, secondary, and /or tertiary amine, and by cleaving the ammonium formate by heating it in fo rmic acid and the amine, characterized in that the primary, secondary, or te rtiary amine is selected from the amines of formula I or the mixtures thereo f, R1 through R3 being identical or different and being hydrogen, linear or branched alkyl radicals having 1 to 18 carbon atoms, cycloaliphatic radicals having 5 to 7 carbon atoms, aryl radicals and/or aryl alkyl radicals, at le ast one of the radicals R1 to R3 carrying a hydroxyl group, and that said hy drogenation is performed in a solvent having a boiling point of >=105°C a t normal pressure, and that the formic acid is obtained in the hydrogenation reaction mixture comprising the high-boiling solvent by thermal cleavage of the ammonium formate and distillation of the formic acid.
