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: The racemization of optically active, optionally substituted aliphatic secondary amines (I) by contacting with hydrogen and a (de)hydrogenation catalyst is carried out in the gas phase. Racemization of optically active amines (I) involves contacting (I), in the gas phase, with hydrogen and a hydrogenation or dehydrogenation catalyst at elevated temperatures. R1 = H, alkyl, cycloalkyl, aralkyl, aryl, heteroaryl or heterocyclyl (all optionally substituted by alkyl, cycloalkyl, alkoxy, aryloxy, alkylamino or dialkylamino); with the proviso that R1 and R2 are different. R2, R3 = alkyl, cycloalkyl, aralkyl, aryl, heteroaryl or heterocyclyl (all optionally substituted by alkyl, cycloalkyl, alkoxy, aryloxy, alkylamino or dialkylamino);
