    摘要: 2- and 3-Nitrobenzaldehydes suitable for use as intermediates for the preparation of pharmaceuticals are obtained in a simple manner and without risk of uncontrolled decompositions by distilling mixtures of nitrobenzaldehyde isomers at bottom temperatures of at most 200.degree. C. in the presence of monomeric and/or polymeric aromatic amines and/or phenols and/or N- and S-containing phenothiazines.
