Description

Pierwszenstwo: 5 listopada 1913 r.Znaleziono, ze zólte barwniki do chro¬ mowania otrzymuje sie przez laczenie kwa¬ su antranilowego, lub jego produktów pod¬ stawienia z kwasami sulfonowemi pyrazo- lonu, lub ich pochodnemi. Barwniki te od¬ znaczaja sie wybitna odpornoscia na kar¬ bonizowanie i na folusz.Przyklad L 171,5 czesci kwasu 5-chlo- ro-2-amino benzoesowego poddaje sie dwu- azowaniu zwyklym sposobem. Roztwór dwuazowy wlewa sie do zalkalizowanego soda roztworu 288,5 czesci I- (2-chloro-5- sulfofenylo)-3-metylo-5-pyrazolonu i stra¬ ca sie po skonczonej reakcji sola.Przyklad IL W podobny sposób zwia¬ zek dwuazowy, wytworzony z 141 czesci kwasu antranilowego, laczy sie z zalka- lizowanym soda roztworem 254 czesci I- (p-sulfofenylo) -3-metylo-5 pyrazolonu.Barwnik zostaje wysolony i przerobio¬ ny w zwykly sposób. PLPriority: On November 5, 1913, it was found that yellow chrome dyes were obtained by combining anthranilic acid or its substitution products with pyrazolone sulfonic acids or their derivatives. These dyes have an outstanding resistance to scarification and foil. Example L 171.5 parts of 5-chloro-2-amino benzoic acid are diazotized in the usual way. The diazotium solution is poured into the alkalized soda solution of 288.5 parts of I- (2-chloro-5-sulfophenyl) -3-methyl-5-pyrazolone and the salt is lost after the reaction is complete. Example IL In a similar manner , made from 141 parts of anthranilic acid, is combined with basalised soda with a solution of 254 parts of I- (p-sulfophenyl) -3-methyl-5-pyrazolone. The dye is salted out and processed in the usual way. PL
