Aniline → N-Cyclohexylaniline

Participants

Reaction Steps

The reaction was carried out using the same apparatus and the same procedure as in Example 1 except that zinc acetate was not employed. In this case, the distilled aniline layer contained as impurities of 200-400 ppm of cyclohexanol, 1300-2200 ppm of cyclohexanone, 80-150 ppm of cyclohexylideneaniline and 20 ppm of nitrobenzene, and the purity of the aniline was only 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 from the start of the reaction, although the content of nitrobenzene in this liquid phase was maintained at 0.01% or less.
