    摘要: The invention relates to a method for obtaining formic acid by the thermal separation of a flow containing formic acid and a tertiary amine (I), wherein a liquid flow which contains formic acid and a tertiary amine (I) in a molar ratio of 0.5 to 5 is produced by combining tertiary amine (I) and a source of formic acid, 10 to 100 wt % of the secondary components contained in said flow are separated, and formic acid is removed by distillation from the resulting liquid flow in a distillation device at a bottoms temperature of 100 to 300°C and a pressure of 30 to 3000 hPa abs, wherein the bottoms product from the distillation device is separated into two liquid phases and the upper liquid phase is returned to the source of formic acid and the lower liquid phase is returned for separation of the secondary components and/or to the distillation device.

    摘要: The invention relates to a method for producing formic acid by reacting carbon dioxide (1) with hydrogen (2) in a hydrating reactor (I) in the presence of a catalyst comprising an element from the 8
    th , 9
    th , or 10
    th group of the periodic system; a tertiary amine containing at least twelve carbon atoms per molecule; and a polar solvent comprising one or more monoalcohols selected from methanol, ethanol, propanols, and butanols, forming formic acid / amine adducts as intermediate products, which are subsequently thermally split, wherein a tertiary amine having a boiling point at least 5°C higher than formic acid is used, and wherein a reaction mixture comprising the polar solvent, the formic acid / amine adducts, the tertiary amine, and the catalyst forms from the reaction in the hydrating reactor (I) and is discharged as a discharge (3) from the reactor.
