<p>This invention is a method of manufacturing aromatic urethane including an aromatic urea production step of reacting an aromatic primary amine, an aromatic nitro-compound, and carbon monoxide with one another, using a catalyst mainly consisting of a compound containing a platinum group metal, and using a compound having a coordination ability to the catalyst as at least part of a solvent, thereby producing N,N min -di-substituted urea, and separating and isolating the produced N,N min -di-substituted urea from the reaction solution, and further including a step of reacting the N,N min -di-substituted urea obtained in the urea production step with an organic compound containing a hydroxyl group to produce the aromatic primary amine and aromatic urethane, and separating the aromatic primary amine to produce aromatic urethane.</p> |
