Description

  

      Zusatzpatent    zum     Hauptpatent    Nr. 206722.    Verfahren zur Herstellung eines neuen     Farbstoffpräparates.       Es wurde gefunden, dass man ein neues,  lösliches     Farbstoffpräparat    erhält, wenn man  auf den     Azofarbstoff    aus dianotiertem     1-Amino-          2,5-diäthoxy-4-aminocarbäthoxybenzol    und  dem     o-Toluidid    der     2.3-Oxynaphthoesäure          Benzoylchlorid-m-sulfosäure    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.       Beispiel     Man verrührt 27,8 Teile des Kupplungs  produktes aus dianotiertem     1-Amino-2,5-di-          äthoxy-4-aminocarbäthoxy-benzol    und     2,3-          Oxynaphthoesäure-o-toluidid    mit 150 Teilen       Pyridin    bei 50-55  .

   Zum Gemenge lässt man  33 Teile geschmolzene     Benzoylchlorid-m-sulfo-          säure    unter     Steigenlassen    der Temperatur  zufliessen, und rührt noch einige Zeit bei  110-115  . Sobald eine klare, braune Lösung  entstanden und eine Probe in Wasser klar  löslich geworden ist, lässt man das Reaktions-         gemisch    auf 50<B>'</B>abkühlen und destilliert einen  Teil des     Pyridins    im Vakuum ab. Den Rück  stand löst man in warmem Wasser, bindet  das     Pyridin    mit Säure, z. B. wässeriger Salz  säure, und fällt das Kondensationsprodukt  mit aassalzenden Mitteln, z. B. Natrium  chlorid.



      Additional patent to main patent No. 206722. 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 dianotized 1-amino-2,5-diethoxy-4-aminocarbethoxybenzene and the o-toluidide of 2,3-oxynaphthoic acid is benzoyl chloride-m-sulfonic acid 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. EXAMPLE 27.8 parts of the coupling product of dianotized 1-amino-2,5-diethoxy-4-aminocarbethoxy-benzene and 2,3-oxynaphthoic acid-o-toluidide are stirred with 150 parts of pyridine at 50-55.

   33 parts of molten benzoyl chloride-m-sulfonic acid are allowed to flow into the mixture, while the temperature is increased, and the mixture is stirred for some time at 110-115. 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 50 and some of the pyridine is distilled off in vacuo. The residue was dissolved in warm water, the pyridine binds with acid, z. B. aqueous hydrochloric acid, and the condensation product falls with aassalzenden agents, for. B. sodium chloride.

PATENTANSPRUCH: Verfahren zur Herstellung eines neuen Farbstoffpräparates, dadurch gekennzeichnet, dass man auf den Azofarbstoff aus dianotiertem 1- Amino - 2,5 - diäthoxy - 4- aminocarbäthoxy- benzol und dem o-Toluidid der 2,3-Oxynaph- thoesäure Benzoylchlorid-m-sulfosäure in Gegenwart von Pyridin einwirken lässt. PATENT CLAIM: Process for the production of a new dye preparation, characterized in that the azo dye from dianotated 1-amino-2,5-diethoxy-4-aminocarbethoxybenzene and the o-toluidide of 2,3-oxynaphthoic acid benzoyl chloride-m -sulfonic acid 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 Aus gangsfarbstoff wieder abscheidet. Es kann zum Färben oder Drucken von Textilien ver wendet werden. The new preparation forms a dark-colored powder that dissolves in water with a brown color and, when alkalis are added, deposits the starting dye again. It can be used for dyeing or printing textiles.
