Abstract: The invention relates to a method of avoiding corrosion in the separation of methylamine from a product stream ( 10 ) which is obtained in the preparation of methylamines by gas-phase reaction of methanol and ammonia and includes monomethylamine, dimethylamine, trimethylamine, ammonia and methanol as components, where ammonia is separated off by pure distillation in a first column ( 1 ), the remaining components of the product stream obtained as bottoms ( 12 ) are fed to a second column ( 2 ). Trimethylamine ( 14 ) is separated off in the second column ( 2 ) by extractive distillation with introduction of water. The further components of the product stream obtained as bottoms ( 15 ) from the second column ( 2 ) are fed to a third column ( 3 ), in which monomethylamine and dimethylamine are separated off at the top. The monomethylamine and dimethylamine are separated by distillation in a fourth column ( 4 ). To avoid corrosion alkali metal hydroxide is added to the second or third column ( 3 ).

Abstract: The invention relates to a process for preparing methylamines by gas-phase reaction of methanol and ammonia as starting materials at a pressure in the range from 15 to 30 bar in the presence of heterogeneous catalyst. The starting materials are vaporized in one or more heat exchangers (1, 2, 3), superheated to produce a feed gas stream and subsequently fed into a reactor (4), with the mixing of the starting materials being able to be carried out in the feed stream to one of the heat exchangers (1, 2, 3) or at any desired position in a heat exchanger (1, 2, 3). A product gas stream comprising monomethylamine, dimethylamine and trimethylamine and also reaction by-products is taken off from the reactor (4). To control the reactor inlet temperature of the starting materials to a temperature in the range from 360° C. to 370° C., all or some of the feed gas stream or the product gas stream is passed through an adjustable valve (5) in order to vary the pressure and thus the condensation temperature.

Abstract: Pure isophorone-diamine (IPDA) with a cis/trans isomer ratio (CTR) of at least 73/27 is obtained by (a) making crude IPDA with a CTR below 73/27, (b) purifying and separating into fractions with CTR of at least 73/27 (b1) and below 63/37 (b2), (c) isomerizing (b2) in presence of hydrogen, ammonia and catalyst to give IPDA with a CTR of 63/37-66/34 which is recycled to stage (a). A method (M1) for the production of substantially pure 3-aminomethyl-3,5,5-trimethyl cyclohexylamine (isophorone-diamine; IPDA) with a cis/trans isomer ratio (CTR) of at least 73/27 involves: (a) preparation of crude IPDA with a CTR of less than 73/27, (b) purification and separation to give fractions (b1) with a CTR of at least 73/27 and (b2) with a CTR of less than 63/27 and (c) isomerization of (b2) in presence of hydrogen, ammonia and a hydrogenation catalyst to give IPDA with a CTR of 63/37-66/34 which is then recycled to stage (a). An Independent claim is also included for a method (M2) for the production of IPDA with a CTR in the range 63/37 to 66/34 by reacting IPDA with any CTR value with hydrogen and ammonia in presence of a hydrogenation catalyst.

Abstract: Recovery of isophoronediamine (IPDA) comprises preparation of IPDA having a cis/trans isomer ratio of less than 73/27 and separation into at least 5 fractions by distillation including an IPDA fraction having a cis/trans ratio of greater than 73/27 and a fraction having a cis/trans ratio of less than 66/34. A process for the recovery of 3-aminomethyl-3,5,5-trimethylcyclohexylamine (isophoronediamine, IPDA) comprises; (a) preparation of IPDA having a cis/trans isomer ratio of less than 73/27; (b) introduction of IPDA to the middle region of a distillation column having inserts and distillation of IPDA at 5-300 degreesC and 10-2000 mbar; (c) optionally further purification of the IPDA from (b) by distillation in at least one further column whereby the IPDA from step (b) and (c) are separated into at least 5 fractions comprising an organic fraction (1a) containing impurities having a lower b. pt. than trans-IPDA, an aqueous fraction (1b) containing impurities having a lower b. pt. than trans-IPDA, a fraction (2) containing impurities having a higher b. pt. than cis-IPDA, an IPDA fraction (3) having a cis/trans ratio of greater than 73/27 and an IPDA fraction (4) having a cis/trans ratio of less than 66/34.
