Abstract: An oxidic composition which is suitable as a catalyst having divalent and trivalent iron in an atomic ratio of divalent to trivalent iron in the range from greater than 0.5 to 5.5 and oxygen as a counterion to the divalent and trivalent iron. The catalyst composition is useful in the hydrogenation of nitriles to amines.

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.

Abstract: In a coated catalyst having a core and at least one shell surrounding the core, the core is made up of an inert support material, the shell or shells is/are made up of a porous support substance, with the shell being attached physically to the core, and a catalytically active metal selected from the group consisting of the metals of the 10th and 11th groups of the Periodic Table of the Elements is present in finely divided form or a precursor of the catalytically active metal is present in uniformly distributed form in the shell or shells. The coated catalyst of the present invention is suitable for the reduction of unsaturated hydrocarbons. Here, better selectivities than in the case of previously known coated catalysts can be achieved. A process for producing the coated catalyst is also described.
