    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 invention relates to a method for producing ethyldimethylamine and triethylamine, comprising the steps of (i) reacting a mixture from diethylamine and dimethylamine with ethylene in the presence of a catalyst from the group of the alkalimetal dimethylamides, alkalimetal diethylamides and alkalimetal hydrides, (ii) removing the catalyst, (iii) separating by distillation the obtained mixture into triethylamine and ethyldimethylamine and optionallydiethylamine and dimethylamine, (iv) optionally returning the catalyst and the educt amines to the reaction. The inventive method allows t he coupled production of ethyldimethylamine and diethylamine in a simple proces s.

    Abstract: The present invention relates to a method for producing dialkylamides of the alkali metals by reacting the corresponding dialkylamine with the corresponding alkali metal in the presence of an electron donor substance of the group 1,3-butadiene, isoprene, naphthalene and/or styrene with the formation of low quantities of butenyl dialkylamine. According to said method, the corresponding alkali metal is introduced and suspended in a solvent and the dialkylamine and the electron donor substance are added, such that the dialkylamine is present in an amount up to 45 wt. %, preferably up to 25 wt. %, in particular up to 15 wt. % and the butadiene is present in an amount up to 5 wt. %, preferably up to 3 wt. %, in particular up to 1.5 wt. %.

    Abstract: Method for production of n-butylamines involves hydroamination of a butadiene-containing mixture (from cracking fractions, LPG/LNG dehydrogenation or GTL technology) with a primary or secondary amine in presence of alkali metal or metal amide catalyst, followed by transalkylation and hydrogenation. Method for the production of n-butyl-amines (I) from a 1,3-butadiene-containing mixture (II) obtained by cracking petroleum fractions or from the dehydrogenation of LPG or LNG or from GTL technology, involves: (a) reaction of (II) with a primary and/or secondary amine (III) under hydroamination conditions in the presence of alkali metal, metal monoalkylamide, metal dialkylamide or a metal amide of amine (III) as catalyst; (b) reaction of the hydroamination product under transalkylation conditions; and (c) reaction under hydrogenating conditions.
