Versuchsvorschrift

Reaction was carried out by the use of the same apparatus and the same procedure as in Example 1 except that zinc acetate was not employed. In this case, a distilled aniline layer contained, as impurities, 200-350 ppm of cyclohexanol, 1300-2200 ppm of cyclohexanone, 70-130 ppm of cyclohexylideneaniline and 20 ppm or less of nitrobenzene, and the purity of the aniline was merely 99.68-99.80%. Furthermore, in the liquid phase in the reactor, N-cyclohexylaniline was formed rapidly and its content reached about 1.7% after 9 hours had elapsed since the start of the reaction, although the content of nitrobenzene in this liquid phase was maintained at 0.01% or less.
