Process for the preparation of amines from olefines using PSH-3, MCM-22, SSZ-25 zeolithes or mixtures thereof

摘要

Amine cpds. of formula CH(R5)(R6)-C(R3)(R4)-N(R1)(R2) (I) are pred. by reacting olefins of formula C(R5)(R6)=C(R3)(R4) (II) with NH3 or prim. or sec. amines of formula NH(R1)(R2) (III) at 200-350 degrees C and 100-300 bar, using zeolite type PSH-3, MCM-22 and/or SSZ-25 as a heterogeneous catalyst. R1-R6 = H, 1-20 C alkyl, 2-20 C alkenyl, 2-20 C alkynyl, 3-20 C cycloalkyl, 4-20 C alkyl-cycloalkyl, 4-20 C cycloalkyl-alkyl, aryl, 7-20 C alkylaryl or 7-20 C aralkyl; or R1+R2 = opt. unsatd. 3-9 C alkylene chain; and R3 or R5 = 21-200 C alkyl or alkenyl; or R3+R5 = 2-12 C alkylene di-chain.
