Description

  

  Verfahren zur Herstellung eines neuen Farbstoffes.    Es     wurde    gefunden, dass man einen  neuen, wertvollen Farbstoff erhält, wenn  man den     Azofarbstoff,    den man durch Kup  peln von 1     Mol.        diazotiertem        5-Nitro-2-          amino-l-phenol    mit 1     Mol.        1-Naphthylamin-          5-sulfosäure    erhalten kann, mit     Chromfluo-          rid    behandelt. Der neue Farbstoff stellt ein  schwärzliches Pulver dar und färbt Wolle  aus schwefelsaurem Bade in grünen Tönen  mit vorzüglichen Echtheitseigenschaften.  



  <I>Beispiel:</I>  50 Teile- des     Natriumsalzes    des aus     di-          azotiertem        5-Nitro-2-amino-l-phenol    und     1-          Naphthylamin-5-sulfosäure    erhältlichen Farb  stoffes werden in 900 Teilen Wasser kochend  gelöst, mit 18 Teilen Chromoxyd in Form  von     Chromfluorid    versetzt und in Gegenwart    von Glaspulver längere Zeit rückfliessend  gekocht. Durch Eindampfen und     Aussalzen          wird    der neue chromhaltige Farbstoff ge  wonnen.



  Process for the production of a new dye. It has been found that a new, valuable dye is obtained if the azo dye, which is obtained by coupling 1 mol of diazotized 5-nitro-2-amino-1-phenol with 1 mol. 1-naphthylamine-5-sulfonic acid can be obtained, treated with chromium fluoride. The new dye is a blackish powder and dyes wool from sulfuric acid bath in green shades with excellent fastness properties.



  <I> Example: </I> 50 parts of the sodium salt of the dye obtainable from diacotized 5-nitro-2-amino-1-phenol and 1-naphthylamine-5-sulfonic acid are dissolved in 900 parts of boiling water with 18 parts of chromium oxide are added in the form of chromium fluoride and refluxed for a long time in the presence of glass powder. The new chromium-containing dye is obtained by evaporation and salting out.
