Abstract: The invention relates to a method for producing formates according to which: (a) methyl formate is partially hydrolyzed with water; (b) methyl formate an d methanol are separated by distillation from the reaction mixture obtained in step (a) while forming a stream containing formic acid and water, and; (c) t he stream containing formic acid and water from step (b) is brought together wi th the corresponding formate while forming a mixture containing the formate and water. The invention also relates to a device for producing these formates a nd to the use thereof.

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.

Abstract: Joint production of formic acid with a \- 2C carboxylic acid (or derivative) involves transesterifying a formic ester (I) with a \- 2C carboxylic acid (II) to give formic acid (III) and the corresponding carboxylic acid ester (IV), and carbonylating part of (IV) to the corresponding carboxylic acid anhydride (V).
