Abstract: A process for preparing formic acid by thermal cleavage of quaternary ammonium formates of the general formula I (* CHEMICAL STRUCTURE *) (I) where R1, R2 and R3 are C1- to C14-alkyl, C3- to C8-cycloalkyl, aryl or C7- to C16-aralkyl, or together are 1,4- or 1,5-alkylene which is unsubstituted or substituted one to four times by C1-to C4-alkyl, with the proviso that the sum of the carbon atoms of R1, R2 and R3 in the quaternary ammonium formates I is 7 to 40, comprises carrying out the cleavage in the presence of secondary formamides of the general formula II (* CHEMICAL STRUCTURE *) (II) where R4 and R5 are C2- to C10-alkyl, C3- to C8-cycloalkyl, aryl or C7- to C16-aralkyl, or together are 1,4- or 1,5-alkylene which is unsubstituted or substituted one to four times by C1- to C4-alkyl, which formamides boil 30 degrees to 150 degrees C. lower than the tertiary amine of the general formula III (* CHEMICAL STRUCTURE *) (III) where R1, R2 and R3 have the abovementioned meanings, contained in the formate I.
