Abstract: A process for the preparation of racemic amines of the formula I where R1 and R2 are different and R1, R2, R3 are alkyl, cycloalkyl, arylalkyl, aryl, heteroaryl and heterocyclic radicals and R3 can also be hydrogen, where the radicals can bear substituents selected from the group consisting of alkyl, cycloalkyl, alkoxy, aryloxy, amino, alkylamino and dialkylamino, which comprises simultaneously reacting in situ the corresponding optically active amine I and the secondary alcohol of the formula II and/or the unsymmetrical ketone of the formula III and the amine of the formula R3NH2 in the presence of hydrogen and a hydrogenation catalyst or dehydrogenation catalyst at elevated temperature.

Abstract: Production of anhydrous 2-amino-1-methoxypropane (I) comprises (a) treating an aqueous reaction mixture (II) containing (I), obtained by reacting 1-methoxy-2-propanol with ammonia (NH3) on a catalyst, with aqueous sodium hydroxide (NaOH) solution to form an aqueous phase containing aqueous NaOH solution and a phase containing (I); (b) separating the phase (III) containing (I) from the aqueous phase; and (c) distilling (III) to separate an azeotrope of water and (I), which is recycled to step (a) or (b), and then anhydrous (I). Also claimed is a method of separating water from (II) in this way.

Abstract: In a process for the N-alkylation of amines in which alcohols are reacted with alkylamines or dialkylamines in the presence of hydrogen, the reaction takes place on a catalyst based on copper and magnesium silicate and containing, in each case independently, 0 to 2 % by weight of BaO, Cr2O3 and/or ZnO. The amines employed are mono- or dimethylamine or mono- or diethylamine, the alcohols employed are .alpha.,.omega.-diols, in parti cular diethylene glycol or pentanediol. In particular there is reaction of diethylene glycol with monomethylamine and/or monoethylamine to give N-methylmorpholine and/or N-ethylmorpholine.
