    Abstract: The invention relates to a method for obtaining hexamethylene diamine (I) from a mixture (II) containing (I) hexamethylene diamine, (III) hexamethylenimine, (IV) a compound selected from the group consisting of 2-aminomethyl cyclopentylamine and 1,2-diaminocyclohexane, (V) an imine, and (VI) adipodinitrile and 6-aminocaproic acid nitrile. According to said method, (a) a mixture (II) is subjected to distillation, yielding (a1) a low-boiling fraction which essentially contains (III), (a2) a medium-boiling fraction (VII) containing (I), (IV) and (V), and (a3) a high-boiling fraction containing (V) and (VI); (b) a mixture (VII) is subjected to distillation, yielding (b1) an overhead which essentially contains (IV) and (b2) a mixture (VIII) containing (I) and (V) as bottom residue; and (c) a mixture (VIII) is subjected to distillation, yielding (c1) (I) as overhead and (c2) a bottom residue which contains the essential part of (V).

    Abstract: Aliphatic alpha,omega-aminonitriles are prepared by partial hydrogenation of aliphatic alpha,omega-dinitriles at elevated temperatures and superatmospheric pressure in the presence of a base and of a hydrogenation catalyst, by carrying out the hydrogenation in the presence of ammonia and lithium hydroxide or of a compound which gives lithium hydroxide during the hydrogenation.

    Abstract: A PROCESS FOR PREPARING PROPYLENE OXIDE COMPRISES AT LEAST THE FOLLOWING STEPS: (A) PROPENE IS REACTED WITH A HYDROPEROXIDE IN A SOLVENT IN THE PRESENCE OF A ZEOLITE CATALYST TO GIVE A MIXTURE (M0), WHERE THE MIXTURE (M0) COMPRISES PROPYLENE OXIDE, SOLVENT, UNREACTED PROPENE, UNREACTED HYDROPEROXIDE AND OXYGEN. (B) THE PROPYLENE OXIDE IS SEPARATED FROM THE MIXTURE (M0) SO AS TO GIVE A MIXTURE (M1) WHICH COMPRISES UNREACTED PROPENE AND OXYGEN. (C) THE MIXTURE (MI) IS BROUGHT INTO CONTACT WITH A LIQUID MEDIUM COMPRISING AT LEAST A SOLVENT TO GIVE THE MIXTURES (M2) AND (M3), WHERE THE MIXTURE (M3) COMPRISES PART OF THE UNREACTED PROPENE AND OXYGEN AND THE MIXTURE (M2) COMPRISES SOLVENT AND RESIDUAL PROPENE, AND THE MIXTURE (M3) WHICH HAS BEEN SEPARATED OFF AND COMPRISES UNREACTED PROPENE AND OXYGEN HAS A RATIO OF OXYGEN TO PROPENE SUCH THAT THE MIXTURE (M3) IS NOT IGNITABLE, AND THE MIXTURE (M2) IS FED TO AT LEAST ONE REACTION OF PROPENE WITH HYDRO PEROXIDE.
