| titleOfInvention | 2-hydroxy-3-carboxy-naphthaldehyde-1 - in high yield from a bis (naphthylideneimino)methane |
| abstract | Title cpd. (used to prepare azo methine dyes) is prepd. by hydrolysis of the new cpd.: which is itself used in printing inks, distemper paints, lacquers and plastics. Cpd. (I) may be prepd. by reacting 2-hydroxynaphthalene-3-carboxylic acid with hexamethylene tetramine in a low mol. wt. carboxylic acid (except formic) at elevated temps. |
