ABSTRACT:
A process for the preparation of formic acid by the reaction of carbon monoxide with water at temperatures of from 100.degree. to 250.degree. C. and absolute from 100 to 350 bar, in which tertiary amines of the general formula I ##STR1## in which R.sup.1, R.sup.2, R.sup.3 individually denote C.sub.1 -C.sub.14 alkyl, C.sub.3 -C.sub.8 cycloalkyl, aryl, and C.sub.7 -C.sub.16 aralkyl or together denote a 1,4-alkylene group or 1,5-alkylene group optionally mono- to tetra-substituted by C.sub.1 -C.sub.4 alkyl, provided that the total number of carbon atoms in R.sup.1, R.sup.2, and R.sup.3 is from 3 to 40,
are added to the reaction mixture.
