Abstract: Production of propionic acid (or its ester) from acrylic acid (or its ester) comprises: (1) partial dehydrogenation of propane to give a mixture (A); (2) partial oxidation of propylene in (A) to form a mixture (B); and (3) hydrogenation of the acrylic acid in (B) (directly and/or after esterification) to form a mixture (C). At least part of the hydrogen used in step (3) is that formed in step (1). Production of propionic acid (or its ester) from acrylic acid (or its ester) comprises: (1) heterogeneously catalyzed partial dehydrogenation of propane in a first reaction zone, to give a product gas mixture (A) containing molecular hydrogen, propylene and unconverted propane; (2) charging the propylene in (A) to a second reaction zone, in which the propylene is subjected to selective, heterogeneously catalyzed partial gas phase oxidation with molecular oxygen to form a product gas mixture (B) containing acrylic acid; and (3) charging the acrylic acid in (B) (directly and/or after esterification) to a third reaction zone, in which the acrylic acid (or ester) is hydrogenated with molecular hydrogen to form a product gas mixture (C) containing propionic acid and/or its ester. At least part of the hydrogen used in step (3) is that formed in step (1).

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.
