Abstract
A method for producing an aromatic primary amine, characterized by hydrogenating an aromatic nitrile at a low partial pressure of hydrogen in a heterogeneous system comprising a non-reductive polar solvent and a nickel-immobilized catalyst suspended therein was proposed. By such method, an aromatic primary amine which is industrially useful as a medicine, agricultural chemical, dye surfactant, chemical agent, etc. can be produced in a high yield.
