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.
