  Verfahren zur Herstellung eines neuen     chrofnierbaren        Orthoozyazofarbstof%s.       Es wurde gefunden, dass mau durch Kup  peln von     diazotiertem        5-Nitro-4-ehlor-2-atnitio-          1-oxybenzol    mit der     N-Methyleiisulfosäitre     der     2-Amittonaphtalin-7-sulfosäure    einen neuen       chromierbaren        Orthooxyazofarbstoff    herstellen  kann.

   Dieser     Farbstoff    bildet ein dunkel  violettes Pulver und färbt Wolle aus saurem  Bade in blaustichig bordeauxroten Tönen an,  welche beim     Nachehromieren    in ein     grüii-          stichiges    Blau von guter Walk- und     Potting-          echtheit    übergehen.  



       Beispiel     18,8 kg     5-Nitro-4-eltlor-2-atnino-l-oxyben-          zol    werden mit 30 kg Salzsäure von<B>30'</B>     ;'o     und 7,2 kg technischem     Natriumnitrit    wie  üblich     diazotiert.    Die     Diazolösung    lässt man  einlaufen in eine Lösung von 32 kg der       N-Methylensulfosäure    der     2-Aminonaphtaliir          7-sulfosäure    (dargestellt durch Einwirkung  von Formaldehyd und     Natriumbisulfit        ;

  tuf            2-aminottaphtalin-7-sulfosaures    Natron) gelöst  in 100 Liter Wasser. Die Kupplung ist bei  gewöhnlicher     Temperatur    innerhalb einiger       Stunden    beendigt, dann wird der     Farbstoff     durch Aassalzen     abgeschieden.  



  Process for the production of a new chromable orthozyazo dye% s. It has been found that by coupling diazotized 5-nitro-4-chloro-2-atnitio-1-oxybenzene with the N-methyleiisulfosäitre of 2-amittonaphthalene-7-sulfonic acid, a new chromable orthooxyazo dye can be produced.

   This dye forms a dark violet powder and dyes wool from an acid bath in bluish, burgundy-red tones, which, when retouched, turn into a greenish blue of good milled and potting fastness.



       Example 18.8 kg of 5-nitro-4-eltloro-2-atnino-1-oxybenzene are diazotized as usual with 30 kg of hydrochloric acid of 30 ';' o and 7.2 kg of technical grade sodium nitrite . The diazo solution is allowed to run into a solution of 32 kg of N-methylene sulfonic acid, 2-aminonaphthalene 7-sulfonic acid (produced by the action of formaldehyde and sodium bisulfite;

  tuf 2-aminottaphthalene-7-sulphonic acid soda) dissolved in 100 liters of water. The coupling is completed within a few hours at ordinary temperature, then the dye is deposited by carrion salts.

PATENTANSPRUCH: Verfahren zur Herstellung eines neuen ehromierbaren Orthooxyazofarbstoffes, dadurch gekennzeichnet, dass diazotiertes 5-Nitro-4- ch@or-2-amino-l-oivbenzo@ mit der N-11Iethv- lensulfosäure der 2-Amirtonaphtalin-7-salfo- säure gekuppelt wird. PATENT CLAIM: Process for the production of a new honorable orthooxyazo dye, characterized in that diazotized 5-nitro-4-ch @ or-2-amino-l-oivbenzo @ with the N-11Iethv- lene sulfonic acid of 2-amirtonaphthalene-7-naphthaic acid is coupled. Der erhaltene Farb stoff bildet ein dunkelviolettes Pulver und färbt Wolle aus saurem Bade in blaustichig bordeauxroten Tönen an, welehe beim Nach- ehrontieren in ein grünstichiges Blau von guter Walk- und Pottingechtheit übergehen. The dye obtained forms a dark purple powder and dyes wool from an acid bath in a bluish tinge of burgundy-red, which, on re-mounting, changes to a greenish blue of good fullness and potting fastness.
