ABSTRACT:
Alkanols, e.g., octanol, are reacted in gas mixtures with excess ammonia and preferably hydrogen at temperatures from 180.degree. to 340.degree. C. over supported catalytic oxides of copper, manganese, antimony and tin at atmospheric to moderate pressures. Depending on the selected catalyst and selected temperature, yields of 40% to 98% of monoalkyl amines or nitriles are produced. Other organic substrates, such as aromatic alcohols and aldehydes, aliphatic aldehydes, esters and primary and secondary amines can also be converted to nitriles at yields greater than 90%. The process is readily adaptable for continuous flow processing.
