Abstract

PURPOSE: To obtain urethane which is a raw material for polyurethane, by reacting an aromatic nitro compound with an OH group-containing organic compound and CO, using a catalyst consisting of metallic palladium or its compound, a vanadium compound, a tertiary amine and hydrogen chloride.
CONSTITUTION: An aromatic compound is reacted with an OH group-containing organic compound, e.g. a mono-or polyhydric alcohol or phenol, and CO in the presence of a catalyst consisting of metallic palladium or its compound, e.g. a palladium halide, etc. in an amount calculated as 0.001W1wt.% of simple palladium, 10W100 gram atoms per gram atom. of Pd of a vanadium compound, e.g. vanadium pentoxide, etc., and 1W50 moles per gram atom Pd of tertiary amine, e.g. pyridine, etc., and 1W10 moles per gram atom of vanadium of hydrogen chloride under a partial pressure of CO of 1W500 kglcm2 at 100W240°C for 10 minW6 hr to give urethane.
