Abstract: The invention relates to a method for producing formic acid formates, whereby (a) formic acid methyl ester is partially hydrolysed with water; (b) formic acid methyl ester and methanol are separated by distillation from the reaction mixture obtained in step (a), forming a current containing formic acid and water; (c) the current obtained in step (b), containing the formic acid methyl ester and optionally methanol, is converted into a current containing formate and water, by (i) reaction with a basic compound having a pKa value of the corresponding acid of the corresponding dissociation step of = 3, measured at 25 ~C in an aqueous solution, in the presence of water, and (ii) separation by distillation of the methanol; and (d) the current obtained in step (b), containing formic acid and water, and the current obtained in step (c), containing formate and water, are combined to form a mixture containing the formic acid formate and water. The invention also relates to a device for producing said formic acid formates and to the use of the same.

Abstract: The present invention describes a process for the preparation of ethyldimethylamine and triethylamine with the following steps: (i) reaction of a mixture of diethylamine and dimethylamine with ethylene in the presence of a catalyst from the group of alkali metal dimethylamides, alkali metal diethylamides and alkali metal hydrides (ii) removal of the catalyst (iii) distillation separation of the resulting mixture in triethylamine and ethyldimethylamine and optionally diethylamine and dimethylamine (iv) optional return of the catalyst and of the starting amines to the reaction. The process according to the invention permits the coproduction of ethyldimethylamine and diethylamine in a simple process.

Abstract: Production of propionic 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) containing propionic acid and/or its ester 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) being that formed in step (1).

Abstract: The invention relates to a method for producing alkylamines (product amines) by reacting alkenes with amines (educt amines) in the presence of a metal hydride or a metal as a catalyst. Said reaction is carried out in the presence of a co-catalyst, the acidity of said co-catalyst being higher than that of the educt amine. The invention also relates to the use of said co-catalyst in the production of alkylamines (product amines) by reacting alkenes with amines (educt amines) in the presence of a metal hydride or a metal as a catalyst.

Abstract: Preparation of amines(I) by hydrogenation of nitro compounds(II) is carried out in a vertical reactor having length greater than its diameter. At the top is a downwards-directed nozzle supplying starting material and recyled reaction mixture, and an outlet from which the reaction mixture is pumped to the nozzle through an external circuit. The flow of reaction mixture is reversed at the base of the reactor.

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.
