Azomethines can be prepared by the condensation of cycloalkanones and anilines in the presence of acid homogeneous catalysts while the water of reaction is removed azeotropically, the condensation being carried out in a continuous reaction in a column-like reactor to which a temperature profile is applied, the starting materials being fed in in the low-temperature region, and, of the reaction products, the water of reaction to be removed azeotropically being discharged also in the low-temperature region and the azomethine produced being discharged in the high-temperature region.
