Reaction Steps

The experiment as described in Example 10 was repeated at a temperature of 110° C. using nitrobenzene (7.5 ml) and aniline (4 ml) as feed. Gas-liquid chromatography indicated that the initial amount of aniline had been converted completely and that 1,3-diphenylurea had been formed in high yield (90%, based on aniline. Methyl carbanilate had been obtained in 60% yield, based on nitrobenzene with a nitrobenzene conversion of about 70%). The reaction temperature was then raised to 135° C. and the reaction was allowed to proceed at that temperature for another 5 hours. The total conversion of nitrobenzene amounted to 90% and more methylcarbanilate had been formed, corresponding to the amount of 1,3-diphenylurea converted.
