    Abstract: The invention relates to a method for the production of formic acid formates, wherein a flowing liquid (I) containing formic acid, and a flowing liquid (II) containing a metal formate, are provided. The flowing liquids (I) and (II) are guided to a rectification column such that a higher or equal guiding point for the liquid flow (II) is selected for the rectification column for the liquid flow (I). The liquid flows (I) and (II) in the rectification column are mixed by separating water via the head of the rectification column and the liquid flow is withdrawn from the rectification column, said liquid flow containing the formic acid formate. The invention is characterised in that the liquid flow is obtained as a melt containing at least 0.5 wt. % water.

    Abstract: The calculation of the above balance shows that the division of stream (5) into the streams (5a) and (5b) used here leads to the fact that in the neutralization stage no excess sodium formate is produced, so that any ejection can be omitted. Furthermore, the water content of the stream (14) comprising sodium formate recirculated to the first crystallization stage in this case can be set to a very low value.

    Abstract: A process is proposed for preparing acid formates in which a liquid stream I comprising formic acid and a liquid stream II comprising a metal formate are prepared, the liquid streams I and II are fed to a rectification column in such a manner that a higher or identical feed point to the rectification column is chosen for the liquid stream II than for the liquid stream I, the liquid streams I and II are mixed in the rectification column, with water being removed overhead from the rectification column and a bottoms stream comprising the acid formate is taken off from the rectification column, which comprises the bottoms stream being produced as melt comprising less than 0.5% by weight of water.
