Abstract
Process for the preparation of aromatic urethanes consisting in reacting organic carbonates with aromatic amines in reactors operating in continuous, feeding a total quantity of aromatic amines in a percentage, with respect to the weight of the total mixture, ranging from 4 to 30, and maintening a low concentration of amine in the reactor.
