Monoisopropylamine is prepared by reacting acetone with ammonia and with
hydrogen at elevated temperature and elevated pressure in the presence of
a catalyst, wherein the catalytically active mass of the catalyst
comprises, after its preparation and before the treatment with hydrogen,
from 20 to 90% by weight of aluminum oxide (Al.sub.2 O.sub.3), zirconium
dioxide (ZrO.sub.2), titanium dioxide (TiO.sub.2) and/or silicon dioxide
(SiO.sub.2), from 1 to 70% by weight of oxygen-containing compounds of
copper, calculated as CuO, from 1 to 70% by weight of oxygen-containing
compounds of nickel, calculated as NiO, and from 1 to 70% by weight of
oxygen-containing compounds of cobalt, calculated as CoO.
Monoisopropylamine รจ preparato reagendo l'acetone con l'ammoniaca e con l'idrogeno alla temperatura elevata ed alla pressione elevata in presenza di un catalizzatore, in cui la massa cataliticamente attiva del catalizzatore contiene, dopo la relativa preparazione e prima del trattamento con idrogeno, 20 - 90% del peso dell'ossido di alluminio (Al.sub.2 O.sub.3), diossido di titanio del diossido dello zirconio (ZrO.sub.2), (TiO.sub.2) e/o diossido del silicone (SiO.sub.2), 1 - 70% a peso di i residui ossigeno-contenenti di rame, calcolati come CuO, 1 - 70% a peso di i residui ossigeno-contenenti di nichel, calcolati come NiO e 1 - 70% a peso di i residui ossigeno-contenenti di cobalto, calcolato come coO.
