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.

Abstract: Preparation of a solid sodium formate preparation comprises (i) preparing an aqueous solution, which exhibits formic acid, sodium formate and water; (ii) subjecting the aqueous solution to crystallization and separating a solid phase from mother liquor; (iii) supplying the mother liquor during the production of the aqueous solution, to a distilling device; (iv) mixing the mother liquor with a sodium-containing base to form a mixture containing sodium formate and formic acid; (v) mixing the mixture with formic acid; and (vi) removing the water by withdrawing from the distilling device. Preparation of a solid sodium formate preparation with a content of at least 35 wt.% of formic acid, comprises: (i) at increased temperature, preparing an aqueous solution, which exhibits a molar ratio of formic acid and sodium formate of more than 1.5:1 and a molar ratio of formic acid and water of at least 1.1:1; (ii) subjecting the aqueous solution to crystallization and separating a solid phase from mother liquor; (iii) supplying the mother liquor, optionally after removal of a partial quantity of the mother liquor, during the production of the aqueous solution, to a distilling device; (iv) mixing the mother liquor with a sodium-containing base to form a mixture containing sodium formate and formic acid; (v) mixing the mixture with formic acid under receipt of the aqueous solution; and (vi) removing the water that is not needed for the production of the aqueous solution, by withdrawing from the distilling device.

Abstract: A method for preparing formic acid formates (A) comprises supplying separate liquid streams of formic acid (stream I) and a metal formate (stream II) to a rectification column, with II supplied at the same height as I, or at a higher position. Water is separated as overhead and an (A)-containing sump product is recovered. The sump product is recovered as a melt containing less than 0.5 wt.% water.
