Abstract

3312. Chemische Fabrik Griesheim- Elektron. May 17, 1913, [Convention date]. Formaldehyde condensation products of 2:3- oxynaphthoic acid arylides are prepared by treating the arylides with formaldehyde in presence of alkali. Anilides, toluidides, and their chlor and nitro substitution derivatives, naphthalides, &c. may be used. Azo dyes are obtained by combining the abovedescribed formaldehyde compounds with diazo compounds.
