A method for manufacturing a purified aromatic urethane. Aromatic urethanes are synthesized from a N,N'-disubstituted urea and an organic hydroxyl compound in a reaction medium. The organic hydroxyl compound and the primary aromatic amine side product which are present in the reaction mixture is distilled off and removed from the reaction mixture leaving a distillation bottom. The N,N'-disubstituted urea is separated and removed from the distillation bottom by solvent extraction of the aromatic urethane, and the aromatic urethane in the extract phase obtained in said solvent extraction is separated and purified.

Method of manufacturing aromatic urethanes

A method of manufacturing aromatic urethanes utilizes a urea production process wherein a primary aromatic amine, an aromatic nitro-compound and carbon monoxide are made to react together in the presence of a catalyst and solvents, to produce N,N'-disubstituted urea, the solvlent used in the urea production process consisting at least partly of an amide or oxygen-containing sulfur compound, and having the functions of stabilizing the catalyst and preventing it from separating out in a solution, and of increasing the activity of the catalyst, the quantity of the solvent being sufficient to permit it to fulfill these functions effectively. The method additionally includes an aromatic urethane production process wherein the N,N'-disubstituted urea produced is made to react with an organic compound containing hydroxyl groups, to produce a primary aromatic amine and aromatic urethane, the primary aromatic amine being separated to obtain the aromatic urethane.
