Abstract

PURPOSE: To prepare the titled compound economically, by reacting an aromatic nitro compound and a lower a aliphatic alcohol or a phenol in liquid phase in the presence of a catalyst containing platinum-group metal with CO preparaed by specific method, and circulating and reusing the exhaust gas of the reaction.
CONSTITUTION: An aromatic nitro compound (e.g. nitrobenzene) and a lower aliphatic alcohol (e.g. methanol) or a phenol are made to react with CO in liquid phase in the presence of a catalyst containing a platinum-group metal (e.g. Pd, Rh, etc.) at 100W250°C to obtain an aromatic urethane. The amount of the alcohol or phenol is 2W400mol, pref. 5W50mol per 1mol of the nitro group of the aromatic nitro compound. The CO gas is prepared by passing a mixed gas containing CO2 and O2 through the layer of coke heated at ≥900°C. The exhaust gas obtained after the completion of the urethane-forming reaction is recycled to the above coke layer.
