| titleOfInvention | Method of preparing 2,2-disubstituted pentane 1,5-diamines |
| abstract | a) die 4-Cyanobutanale der Formel II in einem ersten Reaktionsraum mit überschüssigem Ammoniak an aciden Heterogenkatalysatoren bei Temperaturen von 20 bis 150°C und Drücken von 15 bis 500 bar umsetzt und b) die entstandenen Reaktionsprodukte in einem zweiten Reaktionsraum mit überschüssigem Wasserstoff in Gegenwart von überschüssigem Ammoniak an cobalt-, nickel-, ruthenium- und/oder anderen edelmetallhaltigen Katalysatoren, gegebenenfalls mit basischen Komponenten oder auf basischen oder neutralen Trägern bei Temperaturen von 60 bis 150°C und Drücken von 50 bis 500 bar hydriert sowie neue 2,2-disubstituierte Pentan-1,5-diamine der allgemeinen Formel I'n in der die Substituenten R 1' und R 2' unabhängig voneinander C₁- bis C₁₀-Alkyl, C₂- bis C₁₀-Alkenyl bedeuten oder gemeinsam für eine gegebenenfalls durch eine bis fünf C₁- bis C₄-Alkylgruppen substituierte C₄- bis C₇-Alkylenkette stehen, mit der Maßgabe, daß R 1' und R 2' nicht gleichzeitig Methyl bedeuten. Process for the preparation of 2,2-disubstituted pentane-1,5-diamines of the general formula I. in which the substituents R¹ and R² independently of one another are C₁ to C₁₀ alkyl, C₂ to C₁₀ alkenyl or together represent a C₄ to C₇ alkylene chain which is optionally substituted by one to five C₁ to C₄ alkyl groups, from 2, 2-disubstituted 4-cyanobutanal of the general formula II in which the substituents R¹ and R² have the abovementioned meanings, in two spatially separate reaction spaces a) the 4-cyanobutanals of the formula II are reacted in a first reaction chamber with excess ammonia over acidic heterogeneous catalysts at temperatures from 20 to 150 ° C. and pressures from 15 to 500 bar and b) the reaction products formed in a second reaction space with excess hydrogen in the presence of excess ammonia over cobalt-, nickel-, ruthenium- and / or other noble metal-containing catalysts, optionally with basic components or on basic or neutral supports at temperatures of 60 to 150 ° C and pressures of 50 to 500 bar hydrogenated and new 2,2-disubstituted pentane-1,5-diamines of the general formula I in which the substituents R 1 ' and R 2' independently of one another are C₁ to C₁₀ alkyl, C₂ to C₁₀ alkenyl or together represent a C₄ to C₇ alkylene chain which is optionally substituted by one to five C₁ to C₄ alkyl groups , with the proviso that R 1 ' and R 2' are not methyl at the same time. |
