Abstract:
A process for preparing amines of the general formula I whereR1,R2,R3,R4,R5,R6 are hydrogen, C1-C20-alkyl, C2-C20-alkenyl, C2-C20-alkynyl, C3-C20-cycloalkyl, C4-C20-alkyl-cycloalkyl, C4-C20-cycloalkyl-alkyl, aryl, C7-C20-alkylaryl or C7-C20-aralkyl, R1 and R2 are together a saturated or unsaturated divalent C3-C9-alkylene chain and R3 or R5 are C21-C200-alkyl, C21-C200-alkenyl or together a divalent C2-C12-alkylene chain, by reacting olefins of the general formula II where R3, R4, R5 and R6 are as defined above, with ammonia or primary or secondary amines of the general formula III where R1 and R2 are as defined above, at from 200 to 350Â° C. and pressures of from 100 to 300 bar in the presence of a heterogeneous catalyst, wherein the heterogeneous catalyst used is a zeolite having an NES structure.
