    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 process is proposed for preparing acid formates by providing a liquid stream I containing formic acid and a liquid stream II containing a metal formate, and mixing the liquid stream I with the liquid stream II, obtaining the corresponding acid formate, which comprises feeding, to the liquid stream I or a precursor thereof, to the liquid stream II or a precursor thereof, or to the mixture of the liquid streams I and II, a liquid stream III containing the following components at contents of in each case >0.1% by weight: metal formate, metal methoxide, methanol and MeFo (MeFo), which is produced in a process for preparing MeFo by carbonylating methanol in a reactor at a pressure up to 50 MPa absolute in the presence of a metal methoxide as homogeneous catalyst.

    Abstract: Formic acid-formates are produced by (a) partial hydrolysis of methyl formate (MF) with water, (b) distillation to give (S1) formic acid and water, (c) conversion of the other product from (b) (mainly MF) into a stream (S2) containing formate and water by reaction with aqueous strong base and distillation of methanol, and (d) combination of (S1) with (S2). A method for the production of formic acid-formates (I) involves: (a) partial hydrolysis of methyl formate (MF) with water; (b) distillation to give a stream (S1) containing formic acid and water; (c) conversion of the MF- and possibly methanol-containing stream from (b) into a formate- and water-containing stream (S2) by (i) reaction with a basic compound of an acid with a pKa value of at least 3 in presence of water followed by (ii) removal of methanol by distillation; and (d) combination of streams (S1) and (S2). An Independent claim is also included for apparatus for the production of (I), comprising: (A) a reactor for the hydrolysis of MF; (B) a distillation column for separating a stream containing MF, formic acid, methanol and water; (C) a column for the hydrolysis of MF with a basic compound with removal of methanol by distillation (with an inlet for the base above the inlet for the product from (B)); and (D) a column connected to the bottom of (B) for removing water from the stream containing formic acid and water.
