J-acid (6-amino-l-naphthol-3-sulfonic acid [87-02-5]) (16), and gamma acid (7-amino-1-naphtho1-3-su1fonic acid [90-51-7]) (17). [Pg.428]

Cl Direct Black 22 [6473-13-8] (Cl 35435) is an example of a tetrakisazo dye, (4,4 -dianainodiphenylainine-2-sulfoiiic acid bisdiazotized and coupled to 2 mol gamma acid which is then bisdiazotized and coupled to 2 mol y -phenylenediamine) which had production of 552 t in 1985. [Pg.432]

Amination of phenoHc derivatives is limited to specially developed catalytic processes for aniline and y -toluidine (3). More general conditions apply to amination of naphthols by the Bucherer reaction. Important intermediates made by a Bucherer reaction include Tobias acid and gamma acid. [Pg.292]
