Abstract
PURPOSE: The reaction between aniline and carbon monoxide in the presence of oxygen is effected using iodine or an iodide as a catalyst to produce almost quantitatively title compound useful for intermediate of stabilizer for organic peroxides, agricultural chemicals and others.
CONSTITUTION: The reaction between aniline and carbon monoxide in the presence of oxygen as air is effected using iodine or an iodide as potassium iodide as a catalyst to produce diphenylurea wherein the partial pressure of carbon monoxide is 5W 60kg/cm2, that of the air is 10W60, maximum 100kg/cm2 and the reaction temperature is suitably 80W110°C.
EFFECT: This reaction is relatively mild among pressurized processes.
