Description

W niemieckim patencie Nr 263192 jest zastrzezony sposób otrzymywania zapra¬ wowych jednoazobarwników przez zlacze¬ nie dwuazowego kwasu o-aminofenolo- sulfonowego i jego pochodnych z 1-acidylo- amino-7-oksynaftalinami. Jako pochodne acydylowe, które moga byc uzyte dla pro¬ cesu, przytacza opis zwiazki acetylowe i benzoilowe, wiec pochodne kwasów karbo- nowych.Znaleziono nastepnie, ze pochodne kwa¬ sów karbonowych daja sie zastapic odpo- wiedniemi pochodnemi kwasów arylo-sul- fonowych, przyczem otrzymuje sie barwni¬ ki, które maja nietylko zalety opisane w pa¬ tencie niemieckim 263192, gdyz barwia w tonach jeszcze zielenszych i wykazuja zwiekszona odpornosc.Przyklad.Zwiazek dwuazowy, przygotowany z 22,4 cz. kwasu 4-chloro-2-amino-l-oksyben- zolo-6-sulfonowego i 6,9 cz. azotynu sodu w obecnosci kwasu solnego, dolewa sie do wodnego roztworu 32,8 cz. 1-toluolo-sulfa- mino-7-oksynaftaliny w 24 cz. lugu sodo¬ wego o 40° Be, zadanej 18,5 cz. bezwod¬ nego weglanu sodowego, przy mieszaniu i oziebianiu. Po skonczonej reakcji ogrze¬ wa sie, wysala barwnik i obrabia go w zwy¬ kly sposób. Barwi on welne w obecnosci zapraw chromowych zielono-czarno, trwale.Inne kwasy o-amino-fenolo-sulfonowe, np. kwas 4-chloro-2-amino-l-oksybenzolo- 5-sulfonowy lub kwas 6-nitro-2-amino-l- oksybenzolo-4-sulfonowy, prowadza do po¬ dobnych rezultatów. PL PLGerman patent No. 263192 claims a method for obtaining monoazo mordants by combining diazo o-aminophenolsulfonic acid and its derivatives with 1-acidylamino-7-oxynaphthalenes. As acid derivatives that can be used for the process, the description cites acetyl and benzoyl compounds, i.e. derivatives of carbonic acids. It was then found that the carbonic acid derivatives can be replaced by the corresponding derivatives of arylsulfonic acids, thereby obtaining dyes that have not only the advantages described in German patent 263192, as they dye in even greener shades and show increased fastness. Example. A diazo compound, prepared from 22.4 parts of 4-chloro-2-amino-1-oxybenzole-6-sulfonic acid and 6.9 parts of sodium nitrite in the presence of hydrochloric acid, is added to an aqueous solution of 32.8 parts of 1-Toluene-sulfamino-7-oxynaphthalene in 24 parts of 40° B.E. sodium hydroxide solution, mixed with 18.5 parts of anhydrous sodium carbonate, while stirring and cooling. After the reaction is complete, the dye is heated, separated, and processed in the usual manner. It dyes wool green-black, permanently, in the presence of chrome mordants. Other o-aminophenol-sulfonic acids, e.g., 4-chloro-2-amino-1-oxybenzene-5-sulfonic acid or 6-nitro-2-amino-1-oxybenzene-4-sulfonic acid, produce similar results.
