Abstract
Reduction of azo dyes is presented as a method for the synthesis of 2-amino phenol-4-oulfenic acid.
The synthesis and reduction of some azo derivatives of 2-amino phenol-4-sulfonic acid are described.
Preparation of the diazonium compounds of aniline, vitro aniline, 1-amino-2-nanhthol, 1-amino-2-naphthol-1-sulfonic acid, 2-amino phenol-4-sulfonic acid, 1-naphthol 1-amino, and 2-naphthylamine is discussed and their ability to couple with phenol-4-sulfonic acid evaluated.
Reduction of the resultant azo dyes is discussed with reference to fission and the benzidine rearrangement.
An overall presentation of results is Given in Tables I, II, and III on pages 27 - 29.
