Description

  

  Verfahren zur Herstellung eines neuen     Farbstoffpr        äparates.       Es wurde gefunden, dass man ein neues,  lösliches     Farbstoffpräparat    erhält, wenn man  auf den     Azofarbstoff    aus     diazotiertem        1-Amino-          2,5-diäthoxy-4-aminocarbäthoxybenzol    und  dem     Anilid    der     2.3-Oxynaphthoesäure        Ben-          zoesäure-3-sulfochlorid    in Gegenwart von       Pyridin    einwirken lässt.

   Das neue Präparat  bildet ein dunkel gefärbtes Pulver, das sich  in Wasser mit brauner Farbe löst und auf  Zusatz von Alkalien den     Ausgangsfarbstoff     wieder abscheidet. Es kann zum Färben oder  Drucken von Textilien verwendet werden.    <I>Beispiel:</I>    Man verrührt 27,1 Teile des Kupplungs  produktes aus     diazotiertem        1-Amino-2,5-di-          äthoxy-4-aminocarbäthoxybenzol    und     2,3-Oxy-          naphthoesäureanilid    mit 150 Teilen     Pyridin     bei 50-55  .

   Zum Gemenge streut man 33  Teile     Benzoesäure-3-sulfochlorid    unter Steigen  lassen der Temperatur, und rührt noch einige  Zeit bei 110 bis<B>1150.</B> Sobald eine klare,  braune Lösung entstanden und eine Probe in  Wasser klar löslich geworden ist,     lä.sst    man    das Reaktionsgemisch auf<B>500</B> abkühlen .und  destilliert einen Teil des     Pyridins    im Vakuum  ab. Den Rückstand löst man in warmem  Wasser, bindet das     Pyridin    mit Säure, zum  Beispiel wässeriger Salzsäure, und fällt das  Kondensationsprodukt mit     aussalzenden    Mit  teln, zum Beispiel     Natriumchlorid.  



  Process for the production of a new dye preparation. It has been found that a new, soluble dye preparation is obtained if the azo dye of diazotized 1-amino-2,5-diethoxy-4-aminocarbethoxybenzene and the anilide of 2,3-oxynaphthoic acid is benzoic acid-3-sulfochloride in the presence of Lets pyridine act.

   The new preparation forms a dark-colored powder that dissolves in water with a brown color and, when alkalis are added, redeposits the original pigment. It can be used for dyeing or printing textiles. <I> Example: </I> 27.1 parts of the coupling product of diazotized 1-amino-2,5-diethoxy-4-aminocarbethoxybenzene and 2,3-oxynaphthoic anilide are stirred with 150 parts of pyridine at 50% 55.

   33 parts of benzoic acid-3-sulfochloride are sprinkled onto the mixture, while the temperature is allowed to rise, and the mixture is stirred for some time at 110 to 1150. As soon as a clear, brown solution has formed and a sample has become clearly soluble in water , the reaction mixture is allowed to cool to <B> 500 </B> and some of the pyridine is distilled off in vacuo. The residue is dissolved in warm water, the pyridine is bound with acid, for example aqueous hydrochloric acid, and the condensation product is precipitated with salting-out agents, for example sodium chloride.

PATENTANSPRUCH: Verfahren zur Herstellung eines neuen Farbstoffpräparates, dadurch gekennzeichnet, dass man auf den Azofarbstoff aus diazotier- tem 1-Amino-2,5-diäthoxy-4-aminocarbäthoxy- benzol und dem Anilid der 2,3-Oxynaphthoe- säure, Benzoesäure-3-sulfochlorid in Gegen wart von Pyridin einwirken lässt. PATENT CLAIM: Process for the production of a new dye preparation, characterized in that the azo dye from diazotized 1-amino-2,5-diethoxy-4-aminocarbethoxy-benzene and the anilide of 2,3-oxynaphthoic acid, benzoic acid 3-sulfochloride can act in the presence of pyridine. Das neue Präparat bildet ein dunkel gefärbtes Pulver, das sich in Wasser mit brauner Farbe löst und auf Zusatz von Alkalien den Ausgangs farbstoff wieder abscheidet. Es kann zum Färben oder Drucken von Textilien verwen det werden. The new preparation forms a dark-colored powder that dissolves in water with a brown color and, when alkalis are added, separates the starting dye again. It can be used for dyeing or printing textiles.
