Preparation of amines of formula (I) is claimed, which comprises reacting olefins of formula (II) with ammonia or a primary or secondary amine of formula HN(R<1>)(R<2>) (III) at temperatures of 200-350 degrees C. and pressures of 100-300 bar in the presence of a heterogeneous catalyst comprising type SSZ-37 zeolite. R<1>-R<6> = H, 1-20C alkyl 2-20C alkenyl, 2-20C alkynyl, 3-20C cycloalkyl, 4-20C alkylcycloalkyl, 4-20C cycloalkylalkyl, aryl, 7-20C alkylaryl or 7-20C aralkyl. Or R<1> and R<2> together form a saturated or unsaturated 3-9C alkylene bridge; Or R<3> or R<5> = 21-200C alkyl, 21-200C alkenyl or together form a 2-12C alkylene bridge. |
