Abstract: The invention relates to a method for producing monoisopropylamine (MIPA). According to the inventive method, propine and/or propadiene are reacted with MIPA under hydroamination conditions. The hydroamination product(s) obtained are then reacted with ammonia under transalkylation and hydrogenation conditions.

Abstract: The invention concerns a method for producing ethylamines and butylamines and ethylamine and butylamine mixtures. Said method comprises the following steps: (i) hydroamination of butadiene and ethylene with a monoalkylamine and/or dialkylamine, alkyl may be substituted by ethyl and/or butyl, in the presence of an alkali metal amide as catalyst; (ii) isomerization of the amine obtained during hydroamination (i), optionally after (iia) separating into specific fractions and/or (iib) in hydrogenation conditions and/or (iic) in the presence of ammonia; (iii) separating the product mixture obtained, isolating the desired amine produced and recycling to step (i) the appropriate amine as educt.

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: A gas phase oxidation reactor has one or more endothermic or exothermic stages that take place in the presence of a heterogenic particle catalyst. The catalyst comprises one or more stacked perforated panel(s) (1) with a coefficient of heat conductivity of greater than 30 W/m/K. The perforations extend in-line through the stacked sheet metal plates and hold the catalyst particles. The stacked plates are surrounded around the edges by a sleeve separating the gas inlet zone (4) from the gas outlet zone (5). The gas inlet zone (4) from the gas outlet zone (5) are linked only via the perforations (1) in the panels. The panels are sheet metal (e.g. aluminum, copper, silver or their alloys), ceramic or graphite. The perforation diameter is less than 6 mm.
