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.

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: 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.
