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the rectification column are mixed by separating water via the head of the rectification column and the liquid flow is withdrawn from the rectification column, said liquid flow containing the formic acid formate.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: 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.
