Abstract: Water and ammonia are removed from crude benzophenone-imines obtained by the catalytic reaction of ammonia with benzophenones of formula (I), in which R , R = (a) halogen, hydroxyl, nitro or amino groups, (b) 1-12C linear, branched or cyclic alkyl or alkoxy, optionally substituted with 6-10C aryl, F, Cl or Br, (c) 6-10C aryl or aryloxy, optionally substituted with 1-12C alkyl or alkoxy, (d) heteroalkyl groups comprising alkyl groups as above with in-chain O, S and/or N atom(s), or (e) heteroaryl groups with 5-10 ring atoms containing 1-3 O, S and/or N atoms; m, n = 0-5. The process comprises removing the ammonia by distillation and removing the water by distillation or with a drying agent.

Abstract: In the preparation of amines of formula R5R6CHCR3R4NR1R2 (I) by reacting olefins of formula R5R6C=CR3R4 (II) with ammonia (NH3) or primary or secondary amines of formula HNR1R2 (III) at 200-350 deg. C and 100-300 bar in the presence of a heterogeneous catalyst, the catalyst comprises zeolite with NES structure (2-dimensional pore system with approximate dimensions of 4.7 x 6.0 Angstrom ); in which R1 - R6= hydrogen, 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 R3 + R2 = an (un)saturated 3-9 C alkylene di-chain; and R3 or R5 = 21-200 C alk(en)yl or R3 + R3 = a 2-12 C alkylene chain.
