Description

  

  <B>Zusatzpatent</B> zum     Hauptpatent    Nr. 198710.    Verfahren zur Herstellung eines     BisazofarbstofTes.       Nach dem im Hauptpatent beschriebenen  Verfahren erhält man einen     Disazofarbstoff,     der sich in organischen Lösungsmitteln mit  bräunlich gelber Farbe löst, wenn man     p-          Aminoazobenzol        diazotiert    und die     Diazover-          bindung    mit     p-Isohegylphenol    kuppelt.  



  Wie nun weiter     gefupden    wurde, erhält  man einen     Disazofarbstofl    von ähnlichen Ei  genschaften, wenn man     2.4'-Diamino-diphenyl          tetrazotiert    und die     Tetrazoverbindung    mit       p-Isohegylpheriol    kuppelt.  



  <I>Beispiel:</I>       Klan        tetrazotiert    18,4 Teile     2.4'-Diamino-          diphenyl    unter Zugabe von 100 Teilen Salz  säure, 12       Bd,    mit 13,8 Teilen     Natriumnitrit     und lässt die filtrierte Lösung bei 0   zu einer    Lösung von 35,6 Teilen     p-Isohegylphenol,     16 Teilen     Natriumhydrogyd    und 6 Teilen  eines     Emulgiermittels    einlaufen. Der Farb  stoff wird in üblicher Weise aufgearbeitet.  Er färbt organische Lösungsmittel gelb.



  <B> Additional patent </B> to main patent no. 198710. Process for the production of a bisazo dye. The process described in the main patent gives a disazo dye which dissolves in organic solvents with a brownish yellow color when p-aminoazobenzene is diazotized and the diazo compound is coupled with p-isohegylphenol.



  As has now been found, a disazo dye of similar properties is obtained if 2,4'-diamino-diphenyl is tetrazotized and the tetrazo compound is coupled with p-isohegylpheriol.



  <I> Example: </I> Klan tetrazotizes 18.4 parts of 2,4'-diaminodiphenyl with the addition of 100 parts of hydrochloric acid, 12 Bd, with 13.8 parts of sodium nitrite and leaves the filtered solution at 0 to a solution of 35 , 6 parts of p-isohegylphenol, 16 parts of sodium hydrogen and 6 parts of an emulsifier. The dye is worked up in the usual way. It turns organic solvents yellow.
