Patent number: 4080365Abstract: Aromatic urethanes can be produced in exceedingly improved yield when an aromatic nitro compound, an organic compound containing hydroxyl groups, and carbon monoxide are reacted in the presence of a catalyst composed of metallic (elemental) selenium or a selenium compound and a base serving as promoter, to which reaction system an aromatic amino compound and/or an aromatic urea compound which will be secondarily produced by the reaction has been previously added in order to suppress side reactions. For instance, when nitrobenzene, methanol and carbon monoxide are interacted in the presence of metallic selenium and triethylenediamine, the conversion of nitrobenzene is 68% and the percentage of formed methyl N-phenylcarbamate to the interacted nitrobenzene is 80%, whereas when the reaction is effected under the same reaction conditions indicated above with addition to the reaction system of aniline in an amount of about 15 wt.Type: GrantFiled: May 19, 1976Date of Patent: March 21, 1978Assignee: Mitsui Toatsu ChemicalsInventors: Yutaka Hirai, Katsuharu Miyata, Seiji Hasegawa
