Abstract

PURPOSE: To prepare the titled compound useful as a raw material of polyurethane, easily in high yield, by reacting an aromatic nitro compound with CO in the presence of a main catalyst composed of a platinum-group metal compound and a cocatalyst composed of a specific composite metal oxide under high temperature and pressure.
CONSTITUTION: An aromatic isocyanate is prepared by reacting (A) a 6W32C aromatic mono- or poly-nitro compound (e.g. nitrobenzene) with (B) 3mol, based on 1mol of the nitro group, of CO, in the presence of (C) at least one catalyst selected from (a) a mixture of a compound of a platinum group metal (e.g. Ru, Rh, Pd, etc.) and a heteroaromatic-ring nitrogen compound, (b) a complex of a platinum group metal compound and a heteroaromatic-ring nitrogen compound, and (c) a mixture of the above complex and a heteroaromatic-ring nitrogen compound, using (D) a cocatalyst comprising a composite metal oxide composed of Zn and Mo (the atomic ratio of Zn to Mo is 0.01W100), at 100W250°C under a pressure of 50W500kg/cm2.
