ABSTRACT:
Primary alcohols may be treated with ammonia and hydrogen in the vapor phase in the presence of a catalyst containing copper and chromium to produce nitriles and primary amines. The nitriles produced are readily convertible to the same corresponding primary amines. The reaction may be conducted at a temperature in the range of 240.degree. to 320.degree. C. which is substantially lower than the temperatures used in other methods used to make nitriles. Conversions of the alcohols are 95% or higher, and selectivities to the combined primary amines and nitriles are higher than other methods.
