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. PLThe German patent no. 263192 provides a method for the preparation of sparing mono-dyes by combining diazic o-aminophenol sulfonic acid and its derivatives with 1-acidylamino-7-oxynaphthalines. Acidyl derivatives that can be used in the process are cited in the description of acetyl and benzoyl compounds, so carboic acid derivatives. It was then found that carbon acid derivatives can be replaced with appropriate derivatives of aryl-sulfonic acids, As a result, dyes are obtained, which have not only the advantages described in German Patent 263192, because they dye in even greener tones and exhibit increased resistance. Example. A diazo compound, prepared with 22.4 parts of 4-chloro-2-amino-1-oxybenZole-6-sulfonic acid and 6.9 pts. sodium nitrite in the presence of hydrochloric acid is poured into an aqueous solution of 32.8 parts. 1-toluol-sulfamino-7-oxynaphthaline in 24 parts soda lye at 40 ° Be, the set point is 18.5 parts. anhydrous sodium carbonate, while stirring and cooling. After the reaction is complete, it is heated, releases the dye and treats it in the usual manner. It dyes wool permanently in the presence of chromium mortars. Other o-amino-phenol-sulfonic acids, e.g. 4-chloro-2-amino-1-oxybenzol-5-sulfonic acid or 6-nitro-2-amino acid -1-oxybenzole-4-sulfonic acid gave similar results. PL
