Description

  

  Verfahren     zur    Herstellung eines neuen     Farbstoffes.       Es wurde gefunden,     dass    man einen neuen  Farbstoff erhält, wenn man die     3-Oxynaph-          thalin-1,8-diearbonsäure    mit     Diazobenzol    kup  pelt. Der neue Farbstoff stellt ein braunrotes  Pulver dar und färbt Wolle in gelbroten  Tönen an, die beim     Nachchromieren    nach  braun umschlagen.  



  <I>Beispiel:</I>  <B>9,3</B> Teile Anilin werden wie üblich     diazo-          tiert    und die erhaltene Lösung in eine Lö  sung von 21,4 Teilen     3-Oxynaphthalin-1,8-          diearbonsäureanhydrid    und 40 Teilen Soda in  <B>500</B> Teilen Wasser eingetragen. Der sehr    rasch sich bildende Farbstoff wird     ausgesal-          zen,        filtriert    und getrocknet.



  Process for the production of a new dye. It has been found that a new dye is obtained if the 3-oxynaphthalene-1,8-diacid is coupled with diazobenzene. The new dye is a brown-red powder and dyes wool in yellow-red tones that turn brown when chromium-plating.



  <I> Example: </I> <B> 9.3 </B> parts of aniline are diazotized as usual and the solution obtained is converted into a solution of 21.4 parts of 3-oxynaphthalene-1,8-diacid anhydride and 40 parts of soda added to <B> 500 </B> parts of water. The dye, which forms very quickly, is salted out, filtered and dried.

PATENTANSPRUCH: Verfahren zur Herstellung eines neuen Farbstoffes, dadurch gekennzeichnet, dass man die 3-Oxynaphthalin-1,8-dicarbonsäure mit Diazobenzol kuppelt. Der neue Farbstoff stellt ein braunrotes Pulver dar und färbt Wolle in gelbroten Tönen an, die beim Nachehro- mieren nach braun umschlagen. PATENT CLAIM: Process for the production of a new dye, characterized in that the 3-oxynaphthalene-1,8-dicarboxylic acid is coupled with diazobenzene. The new dye is a brown-red powder and dyes wool in yellow-red shades that turn brown when you listen to it.
