| abstract | 501,763. Amines. KODAK, Ltd. Sept. 6, 1937, No. 24288. Convention date, Sept. 5, 1936. Drawings to Specification. [Class 2 (iii)] Amines are manufactured from compounds capable of being aminated, i.e. alcohols, secondary amines or, when a hydrogenating catalyst is present, mixtures of aldehydes and hydrogen, and aminating agents, i.e. ammonia or primary amines, by spraying a liquid compound to be aminated into an atmosphere of an aminating agent under pressure. Dehydrating or hydrogenating catalysts, e.g metals of group VIII of the periodic system or various oxides, may be suspended in the compound to be aminated. In an example, butyl alcohol is mixed, in a storage tank fitted with a stirrer, with a catalyst prepared by heating a nickel aluminium alloy with caustic soda. The mixture is pumped through a heat exchanger into a reaction chamber, preferably of elongated. construction, containing an atmosphere of ammonia under relatively high pressure and temperature, e.g. 200-1500 lb. per sq. in. and 135-500‹ C., preferably 800-1000 lb. per sq. in. and 215-225‹ C., the temperature being maintained by circulating steam, either saturated and under pressure or superheated, through a jacket surrounding the reaction chamber. A liquid containing butylamine and dibutylamine collects at the bottom of the chamber and is worked up for the separation of its constituents. The butyl alcohol may be replaced by dibutylamine, or by butyraldehyde, in which case hydrogen is also supplied to the reaction chamber. The process may also be applied to the production of amylamines, e.g. from amyl alcohol or valeraldehyde, or of other amines, e.g. propylamine or ethylamine. |
