    摘要: The invention relates to a method for obtaining formic acid by thermally separating a flow containing formic acid and a tertiary amine (I), wherein a liquid flow containing formic acid, tertiary amine (I), and water is produced by bringing together a tertiary amine (I) and a formic acid source in the presence of water, water and organic decomposition products of the tertiary amine (I) are removed, and formic acid is removed from the obtained liquid flow by means of distillation in a distillation device, wherein the removed flow containing water and organic decomposition products of the tertiary amine (I) is separated into two liquid phases, the upper liquid phase is removed, and the lower liquid phase containing water is fed back to the formic acid source.
