Abstract

Procédé de préparation d'amines aromatiques à partir des cyclohexène-2 one-oximes-l correspondantes par chauffage en présence d'agents déshydratants. La particularité essentielle de ce procédé est qu'on utilise les oximes sous la forme de leurs chlorhydrates. Les amines aromatiques ainsi préparées sont de précieux corps intermédiaires, pouvant servir par exemple pour la préparation de colorants.Process for preparing aromatic amines from the corresponding cyclohexene-2 one-oximes-1 by heating in the presence of dehydrating agents. The essential feature of this process is that the oximes are used in the form of their hydrochlorides. The aromatic amines thus prepared are valuable intermediates, which can be used, for example, for the preparation of dyes.
