    Abstract: PROBLEM TO BE SOLVED: To produce a stable benzophenone imine free from a reverse reaction to form benzophenone during storage by distilling ammonia and also removing water using distillation or using non-distillation means from an effluent of a benzophenone imine reaction. SOLUTION: This method is composed of the processes distilling ammonia and removing water using distillation or using non-distillation means from an effluent of a benzophenone imine reactor generated by catalytic reaction of a benzophenone of the formula [R and R are independently a halogen, hydroxy, a 6-10C aryl, a 1-12C alkyl, etc.; (m) and (n) are each independently an integer of 0-5] and ammonia. The distillation is preferably carried out at 20-200 deg.C under a pressure of 1-1,000 mbar.

    Abstract: PROBLEM TO BE SOLVED: To obtain an amine in high yield by reacting an olefin with ammonia, or a primary or secondary amine at given temperature and pressure in the presence of zeolite of NES structure as the heterogeneous reaction catalyst. SOLUTION: The method for producing this amine reacts an olefin shown by formula I (R to R are each H, a 1-20C alkyl, 2-20C alkenyl, 4-20C cycloalkyl-alkyl, or the like), e.g. isobutene, with ammonia, or a primary or secondary amine shown by formula II (R and R are each H, a 1-20C alkyl or the like) at 200 to 350 deg.C and 100 to 300 bar in the presence of zeolite of NES structure as the heterogeneous reaction catalyst, to produce the objective compound shown by formula III (e.g. tert-butylamine). This method gives the objective compound in high yield, high yield per treatment space-time, while controlling deactivation of the catalyst.

    Abstract: PROBLEM TO BE SOLVED: To produce amine in high yield, i.e., in high selectivity and high spatiotemporal yield by reacting ammonia or primary or secondary amine with olefin at high temperature and high pressure by using a specific heterogeneous catalyst. SOLUTION: This objective amine of formula III is obtained by reacting a primary or secondary amine of formula I (R and R are each H, an alkyl, alkenyl, aryl, etc.), or ammonia with an olefin of formula II (R to R are each the same as R or R ) at 200 to 350 deg.C and 100 to 300 bar in the presence of a heterogeneous catalyst consisting of NU-85 zeolite. This NU-85 zeolite catalyst may be ion-exchanged or doped with alkali metal, alkali earth metal or rare earth metal. Also, the catalyst may be subjected to acid treatment by using such an acid as hydrochloric acid or sulfuric acid. Preferably, there is recycled the material which has not been converted yet when the amine of formula III is isolated.

    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.
