Abstract: Adipic acid diamide, used in prepn. of 1, 5-hexamethylene diamine and consequently of synthetic fibres, is prepd. by reacting 2-nitrocyclohexanone, 2-nitrocyclohexenol-1 and/or epsilon -nitrocaproamide (I) with practically anhydrous NH3 above 110 degrees C. Sufficient NH3 is used to provide >=1 (>=1.1) mol. equiv. NH3 w.r.t. (I), in addn. to opt. required mol. equiv. NH3 necessary to dissociate the cyclo-aliphatic ring. Reaction takes place at 110-180 (120-160) degrees C, under autogenous NH3 press., e.g. 75-150 (90-130) atmos., opt. continuously.
