Abstract
Process for the preparation of aromatic or aliphatic-aromatic nitriles by catalytic dehydration of formylamides and transposition at high temperature of the isonitriles that are formed, characterized in that, before passing them through the catalyst, the formyl compounds are evaporated at temperatures that do not produce decomposition, and, using suitable means, the concentration of the vapors, per unit volume, in the catalyst chamber is greatly reduced.
