    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 solvent and of a catalyst by a process which comprises using a catalyst which (a) contains a compound based on a metal selected from the group consisting of nickel, cobalt, iron, ruthenium and rhodium and (b) contains from 0.01 to 25% by weight, based on (a), of a promoter based on a metal selected from the group consisting of palladium, platinum, iridium, osmium, copper, silver, gold, chromium, molybdenum, tungsten, manganese, rhenium, zinc, cadmium, lead, aluminum, tin, phosphorus, arsenic, antimony, bismuth and rare earth metals and (c) from 0 to 5% by weight, based on (a), of a compound based on an alkali metal or on an alkaline earth metal. with the proviso that the component (a) is not based on iron or iron and one of the metals selected from the group consisting of cobalt, ruthenium and rhodium when (b) is a promoter based on a metal selected from the group consisting of titanium, manganese, chromium and molybdenum, and with the further proviso that, when a compound based on only ruthenium or rhodium or ruthenium and rhodium or nickel and rhodium is selected as component (a), the promoter (b) may be dispensed with.

    Abstract: AN ORGANIC COMPOUND HAVING AT LEAST ONE C-C DOUBLE BOND IS EPOXIDIZED BY MEANS OF HYDROGEN PEROXIDE IN THE PRESENCE OF AT LEAST ONE CATALYTICALLY ACTIVE COMPOUND AND AT LEAST ONE SOLVENT, WHEREIN A PRODUCT MIXTURE COMPRISING -HYDROPEROXYALCOHOLS IS REDUCED USING AT LEAST ONE REDUCING AGENT. THE PROCESS ADVANTAGEOUSLY COMPRISES AT LEAST THE FOLLOWING STEPS: (I) REACTING AN ORGANIC COMPOUND HAVING AT LEAST ONE C-C DOUBLE BOND WITH HYDROGEN PEROXIDE IN THE PRESENCE OF AT LEAST ONE CATALYTICALLY ACTIVE COMPOUND AND AT LEAST ONE SOLVENT TO GIVE A PRODUCT MIXTURE P1 COMPRISING A-HYDROPEROXYALCOHOLS; (II) SEPARATING AN EPOXIDE FORMED IN THE REACTION IN STEP (I) AND THE UNREACTED ORGANIC COMPOUND HAVING AT LEAST ONE C-C DOUBLE BOND FROM P1 OR P1' TO GIVE A PRODUCT MIXTURE P2 OR P2', WHERE P2 COMPRISES THE -HYDROPEROXYALCOHOLS FORMED AS BY-PRODUCT IN THE REACTION IN STEP (I) AND P2' IS LARGELY FREE OF -HYDROPEROXYALCOHOLS; (III) TREATING P1 AND/OR P2 WITH AT LEAST ONE REDUCING AGENT SO THAT THE -HYDROPEROXYALCOHOLS ARE CONVERTED INTO CORRESPONDING GLYCOLS TO GIVE A PRODUCT MIXTURE P1' OR P3.
