Abstract A process of producing an omega -hydroxy fatty acid by the step of hydrogenation of a long-chain dicarboxylic acid monoester in the presence of a copper-chromium oxide catalyst. According to the process of the invention, omega -hydroxy fatty acids which are useful in the synthesis of medicaments and in the synthesis of macrocyclic lactones which are used for perfumes, etc. and of various polymers can be produced at low production cost and with good efficiency, using inexpensive raw materials by a simplified procedure.
