Description

  

  Verfahren zur Herstellung eines neuen     Farbstoffes.       Es wurde gefunden, dass man einen neuen  Farbstoff erhält, wenn man die     3-Oxynaph-          thalin-1,8-dikarbonsäure    mit     diazotierter    4  <B>,</B>     Su        .Ifo-2-a,mino-l-phenol-6-karbo-nsäurekuppelt     und den so     erhaltenen    Farbstoff mit     Fluor-          ehrom        behandelt.    Der neue Farbstoff bildet  ein schwärzliches Pulver, löst sich in Was  ser unter Zusatz von Natronlauge mit blau  roter Farbe und erzeugt im Chromdruck auf  Baumwolle sehr echte Bordeaux Töne.  



  <I>Beispiel:</I>  27,7 Teile     4-Sulfo-2-a:mino-l-phenol-6-          kanbonsäure    werden wie üblich     diazotiert    und  in eine     Lösung    von 21,6 Teilen     3-Oxynaph-          thalin-1,8Jdikaxsbonsäureanhydrid,    8 Teilen  Natronlauge und 40 Teilen Soda in 500  Teilen Wasser     eingetragen.    Man rührt,     -bis     die     Dia.zoverbindung    verschwunden ist. Hier  auf salzt man mit Kochsalz aus und filtriert  den ausgeschiedenen Farbstoff.

      27     Teeile    dieses     Farbstoffes    werden in  550 Teilen Wasser     gelöst    und mit einer       Fluorchromlösung,    entsprechend 10     Teilen          Cr203,    versetzt. Man kocht einige Zeit zweck  mässig in Gegenwart von Glaspulver, dampft  teilweise ein und scheidet den neuen Farb  stoff durch     Aassalzen    aus.



  Process for the production of a new dye. It has been found that a new dye is obtained if the 3-oxynaphthalene-1,8-dicarboxylic acid is mixed with diazotized 4 <B>, </B> Su .Ifo-2-a, mino-1-phenol- 6-carbonic acid coupled and treated the dye thus obtained with fluorine-ehrome. The new dye forms a blackish powder, dissolves in water with the addition of caustic soda with a blue-red color and produces very real Bordeaux tones in chrome printing on cotton.



  <I> Example: </I> 27.7 parts of 4-sulfo-2-a: mino-1-phenol-6-kanbonic acid are diazotized as usual and converted into a solution of 21.6 parts of 3-oxynaphthalene-1 , 8Jdikaxsbonsäureanhydrid, 8 parts of sodium hydroxide solution and 40 parts of soda in 500 parts of water. The mixture is stirred until the diazo compound has disappeared. Here it is salted out with common salt and the precipitated dye is filtered off.

      27 parts of this dye are dissolved in 550 parts of water and a fluorochrome solution, corresponding to 10 parts of Cr203, is added. It is expediently boiled for some time in the presence of glass powder, partially evaporated and the new dye is eliminated with carrion salts.

PATENTANSPRUCH: Verfahren -zur Herstellung eines neuen Farbstoffes, dadurch gekennzeichnet, dass man die 3-Oxynaphthalin-1,8-dikarbonsäure mit cliazotierter 4-Sulfo-2-amino-l-phenol-6- karbo.nsäure kuppelt und den so erhaltenen Farbstoff mit Fluorchrom :behandelt. Der neue Farbstoff bildet ein schwärzliches Pul ver, löst sich in Wasser unter Zusatz von Natronlauge mit blauroter Farbe und erzeugt im Chromdruck auf Baumwolle sehr echte Bordeaux Töne. PATENT CLAIM: A process for the preparation of a new dye, characterized in that the 3-oxynaphthalene-1,8-dicarboxylic acid is coupled with cliazotized 4-sulfo-2-amino-1-phenol-6-carbo.nsäure and the dye thus obtained with fluorochrome: treated. The new dye forms a blackish powder, dissolves in water with the addition of caustic soda with a bluish-red color and creates very real Bordeaux tones in chrome printing on cotton.
