Naphthalenol also is used ia the preparation of azo, iadigoid, and nitro, eg, 2,4-dinitro-l-naphthol, dyes, and ia making dye iatermediates, eg, naphtholsulfonic acids, 4-chloro-1-naphthalenol, and l-hydroxy-2-naphthoic acid. 1-Naphthalenol is an antioxidant for gasoline, and some of its alkylated derivatives are stabilizers for plastics and mbber (68). 

Following the 3,4-dihydroisoquinolinium compounds, the isoquino-linium compounds themselves will now be considered. The violet red compound obtained by Zincke by heating i-hydroxy-2-(2,4-dinitro-phenyl)-l,2-dihydroisoquinoline (16a) is the open-chain amino-aldehyde (17) isomeric with (16a) and is not the hemiacetal (18) as assumed by Zincke. This is the first case in which both the members...
