Abstract: A method for the production of formic acid-formates (I) involves (a) partial hydrolysis of methyl formate (MF) with water, (b) distillation to give formic acid and water (stream S1) and (c) combination of (S1) with the corresponding formate (F) to give a mixture of (I) and water. An Independent claim is also included for apparatus for the production of (I), comprising a reactor (A) for the hydrolysis of MF, a distillation column (B) for separating a stream containing MF, formic acid, methanol and water into MF, methanol and a stream (S1) containing formic acid and water, and a column (E) for removing water from S1.

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).

Abstract: Production of beta -hydroxy-alkyl-carbamates in a formulation comprises converting the 1,2-alkylene carbonate component with ammonia and a primary or secondary amine. The conversion is in the presence of a 1-4C alkanol at a temperature of 0-60[deg]C and an absolute pressure of 1-10 bar. Independent claims are also included for: (1) beta -hydroxy-alkyl-carbamates produced by the above process; and (2) the preparation of (meth)acrylated beta -hydroxyalkyl carbamates by enzyme catalyzed conversion of a binary mixture of structural isomer beta -hydroxy-alkyl-carbamates with a (meth)acrylate ester.
