Abstract: The invention relates to a method for producing methyl formate by carbonylating methanol with carbon monoxide in a carbonylation reactor in the presence of a catalyst system containing alkali formate and alkali alcoholate, thereby obtaining a reaction mixture (RG) which contains methyl formate, alkali formate, alkali alcoholate and optionally unreacted methanol and unreacted carbon monoxide and which is removed from the carbonylation reactor. The reaction mixture (RG) contains at least 0.5 wt.% alkali alcoholate, based on the total weight of the reaction mixture (RG), and the molar ratio of alkali formate to alkali alcoholate in the reaction mixture (RG) is greater than 1.

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.
