Abstract
p-Aminoaryl aldehydes of the general formula <FORM:1022741/C2/1> wherein R and R1 each represent a hydrogen atom or an unsubstituted or substituted alkyl, cycloalkyl, or aralkyl, radical or R may also be an aryl radical, or the radicals R and R1, together with the nitrogen atom, can form a heterocyclic ring, and wherein the phenylene ring A may contain further substituents and also a further condensed 6-membered carbocyclic ring, or functional derivatives thereof, are made by reacting a corresponding amino compound which has a hydrogen atom instead of -CHO, at elevated temperature with hexamethylene tetramine and formaldehyde or a formaldehyde-yielding agent, e.g. paraformaldehyde, in the presence of glacial acetic acid, optionally with the addition of acetic anhydride and/or concentrated mineral acid. The hexamethylene tetramine may be replaced by a mixture of ammonia or its salts with weak acids and paraformaldehyde or formaldehyde in aqueous solution or in gaseous form. The preferred temperature range is 80-140 DEG C.
