Reaction Steps

0.29 gram of lithium hydroxide, 0.72 gram of acetic acid, 0.25 gram of sulfur, 0.25 gram of selenium metal, 10 milliliters of nitrobenzene, 15 milliliters of methanol and 15 milliliters of dioxane were charged into a 110 milliliter autoclave maintained under an initial carbon monoxide pressure of 2600 psig and at a temperature of 200° C. for 45 minutes. A nitrobenzene conversion of 98 per cent and a urethane product yield of 88.4 per cent were obtained as determined by gas chromatographic analysis.
