ABSTRACT:
Ammonia may be produced by the catalytic reaction of nitrogen and hydrogen, said reaction being effected in the presence of an activated transition metal macrocyclic compound. The catalyst is exemplified by cobalt phthalocyaninetetrasulfonate which has been activated by the application of a reductive potential in the range of from about -1.0 to about -3.0 volts, an example of this being by treatment with sodium borohydride. If so desired, the reaction may be effected in an inert solvent such as a paraffin, alcohol, etc.
