Process for the preparation of amines from olefines using NU-85 zeolites

摘要

Production of amines of formula R5-CH(R6)-C(R3)(R4)-N(R1)-R2 (I) comprises reacting olefins of formula R5-C(R6)=C(R3)-R4 (II) with NH3 or prim. or sec. amines of formula H-N(R1)-R2 (III) at 200-350 degrees C and 100-300 bar in the presence of a heterogeneous catalyst, "NU-85" (RTM: zeolite). In (I)-(III), R1-R6 = H, 1-20C alkyl, 2-20C alkenyl, 2-20C alkynyl, 3-20C cycloalkyl, 4-20C alkyl-cycloalkyl-(alkyl), aryl, 7-20C alkylaryl, or 7-20C aralkyl; and R1 and R2 together can form a saturated or unsaturated 3-9C alkylene chain.
