ABSTRACT:
Aromatic azomethines are prepared by reacting anilines with formaldehyde and then removing the greater part of the water by distillation, low-boiling alcohols, in certain amounts, being present during the distillation and, if desired, during the reaction or during a part thereof.
The aromatic azomethines obtainable by the novel process are valuable starting materials for the preparation of herbicides, especially pre-emergence herbicides and post-emergence herbicides, fungicides, insecticides, bacteriostatic agents, fungistatic agents and vulcanization accelerators.
