Abstract

In a process for preparing amines of the general formula I ##STR1## where R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5, R.sup.6 are hydrogen, C.sub.1 -C.sub.20 -alkyl, C.sub.2 -C.sub.20 -alkenyl, C.sub.2 -C.sub.20 -alkynyl, C.sub.3 -C.sub.20 -cycloalkyl, C.sub.4 -C.sub.20 -alkylcycloalkyl, C.sub.4 -C.sub.20 -cycloalkylalkyl, aryl, C.sub.7 -C.sub.20 -alkylaryl or C.sub.7 -C.sub.20 -aralkyl, PA1 R.sup.1 and R.sup.2 are together a saturated or unsaturated, divalent C.sub.3 -C.sub.9 -alkylene chain and PA1 R.sup.3 and R.sup.5 are each C.sub.21 -C.sub.200 -alkyl, C.sub.21 -C.sub.200 -alkenyl or together are a divalent C.sub.2 -C.sub.12 -alkylene chain, by reacting olefins of the general formula II ##STR2## where R.sup.3, R.sup.4, R.sup.5 and R.sup.6 are as defined above, with ammonia or primary or secondary amines of the general formula III ##STR3## where R.sup.1 and R.sup.2 are as defined above, at from 200 to 350.degree. C. and pressures of from 100 to 300 bar in the presence of a zeolitic catalyst, the zeolitic catalyst used is a boron BETA-zeolite.
