Process for the preparation of Schiff's bases by the reaction of aromatic amines with ketones ABSTRACT OF THE DISCLOSURE Schiff's bases of the formula are obtained by reacting an amine H2N-R3 with a ketone in presence of calcium hydrogen phos-phate, apatite, aluminum oxide, aluminium hydroxide and/or Fuller's Earth and subsequent removing the water by azeotronic distillation. The products are intermediates for the preparation of phenylene diamines which may be used as age resis-tos for rubber. Le A 19 395 |
