ABSTRACT:
The conversion of alkyl diaminobenzenes to the alkyl amino benzenes is carried out by contacting the alkyl diamino benzene with hydrogen in the presence of a nonsupported cobalt catalyst. Optionally, the reaction is carried out in the presence of water so that the water insoluble product formed can be separated from the water soluble reactants and by-products.
