Abstract: In a process for the continuous hydrogenation of nitrites to primary amines in the liquid phase over a suspended, activated Raney catalyst based on an alloy of aluminum and at least one transition metal selected from the group consisting of iron, cobalt and nickel, and, if desired, one or more further transition metals selected from the group consisting of titanium, zirconium, chromium and manganese, the hydrogenation is carried out in the absence of ammonia and basic alkali metal compounds or alkaline earth metal compounds.

Abstract: A process for the purification of crude caprolactam, prepared by reaction of a mixture comprising 6-aminocapronitrile and water, comprises a three stage distillation process with feeding of the crude caprolactam and an inorganic acid having a b. pt. above the b. pt. of the caprolactam to a first distillation column. A process for the purification of crude caprolactam, prepared by reaction of a mixture comprising 6-aminocapronitrile and water in the presence of a catalyst to form a mixture comprising caprolactam, ammonia, water and high and low b. pt. byproducts followed by removal of ammonia to yield a mixture of caprolactam, water and high and low b. pt. byproducts followed by at least partial removal of water to yield a crude caprolactam containing caprolactam and high and low b. pt. byproducts, comprises: (a) feeding of the crude caprolactam and an inorganic acid having a b. pt. above the b. pt. of the caprolactam to a first distillation column; (b) distillation of the crude caprolactam and inorganic acid to form a sump stream and an overhead stream; (c) feeding of the overhead stream to a second distillation column; (d) distillation of the stream to form a sump stream and overhead stream; (e) feeding of the overhead stream to a third distillation column; (f) distillation of the overhead stream to form a sump stream and purified caprolactam in the overhead stream; and (g) feeding of the sump stream to the first distillation column.
