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: In a continuous process for fractionating a C4 fraction (C4) by extractive distillation using a selective solvent (LM) in an extractive distillation column (EDK), it is proposed that a dividing wall (TW) is installed in the longitudinal direction in the extractive distillation column (EDK) to form a first region (A), a second region (B) and a lower combined column region (C) and a top stream (C4H10) comprising the butanes is taken off from the first region (A), a top stream (C4H8) comprising the butenes is taken off from the second region (B) and a stream (C4H6) comprising the hydrocarbons from the C4 fraction which are more soluble in the selective solvent (LM) than are the butanes and the butenes is taken off from the lower combined column region (C).

Abstract: Selective catalytic gas-phase hydrogenation of alkynes, dienes, alkenynes and/or polyenes in an olefin-containing hydrocarbon stream in a series of two or more reaction zones without feeding part of the hydrocarbon stream between the penultimate and last reaction zones. The process comprises adjusting the hydrogen content before the penultimate zone and the conversion in the penultimate zone so that the reaction mixture leaving the penultimate zone contains at least 0.7 vol.% hydrogen.

Abstract: The invention relates to a method for the production of 3-aminomethyl-3,5,5-trimethylcyclohexylamine (isophorondiamine, IPDA) with a cis/trans isomer ratio of at least 70/30 from 3-cyano-3,5,5-trimethylcyclohexanon (isophorone nitril, IPN), NH3 and H2, wherein hydrogenation is carried out in the presence of a hydrogenation catalyst at temperatures ranging from 50 to 200 DEG C and at a pressure ranging from 50 to 300 bar. The invention is characterized in that the alkali metal content of the hydrogenation catalyst is
