Description

  

  Verfahren zur Herstellung eines     3Ionoazofarbstoffes.       Vorliegendes Patent bezieht sich auf ein  Verfahren zur Herstellung eines     Monoazo-          farbstoffes,    dadurch gekennzeichnet, dass man       diazotiertes        1-(cu-Sulfoäthyl-acetylamino)-4-          aminobenzol    in Gegenwart von     Natriumacetat     mit     1-Benzoylamino-    5     -naphthol-    7     -sulfosäure     kuppelt.  



  Der so erhaltene Farbstoff bildet nach  dem Trocknen ein rotes wasserlösliches Pul  ver und färbt Wolle in lebhaften roten Tönen  von sehr guten Echtheitseigenschaften und  gutem     Egalisierungsvermögen.       <I>Beispiel:</I>    25,8 Teile     1-(oi-Sulfoäthyl-acetylamino)-          4-aminobenzol    werden in der üblichen Weise       diazotiert    und die     Diazolösung    in Gegenwart  von     Natriumacetat    mit 85     Teilen        1-Benzoyl-          amino-    5     -naphthol    - 7 -     sulfosäure    gekuppelt.

      Nach beendeter Kupplung wird der gebildete  Farbstoff abgeschieden und getrocknet.



  Process for the preparation of a 3ionoazo dye. The present patent relates to a process for the preparation of a monoazo dye, characterized in that diazotized 1- (cu-sulfoethyl-acetylamino) -4-aminobenzene is coupled with 1-benzoylamino-5-naphthol-7-sulfonic acid in the presence of sodium acetate .



  The dye thus obtained forms a red, water-soluble powder after drying and dyes wool in vivid red shades with very good fastness properties and good leveling power. <I> Example: </I> 25.8 parts of 1- (oi-sulfoethyl-acetylamino) - 4-aminobenzene are diazotized in the usual way and the diazo solution in the presence of sodium acetate with 85 parts of 1-benzoylamino- 5 - naphthol - 7 - sulfonic acid coupled.

      After the coupling has ended, the dye formed is deposited and dried.

PATENTANSPRUCH: Verfahren zur Herstellung eines Monoazo- farbstoffes, dadurch gekennzeichnet, dass man diazotiertes 1- (o)-Sulfoäthyl-acetylamino) -4- aminobenzol in Gegenwart von Natriumacetat mit 1-Benzoylamino-5-naphthol-7-sulfosäure kuppelt. Der so erhaltene Farbstoff bildet nach dem Trocknen ein rotes wasserslösliches Pul ver und färbt Wolle in lebhaften roten Tönen von sehr guten Echtheitseigenschaften und gutem Egalisierungsvermögen. Claim: Process for the preparation of a monoazo dye, characterized in that diazotized 1- (o) -sulfoethyl-acetylamino) -4- aminobenzene is coupled with 1-benzoylamino-5-naphthol-7-sulfonic acid in the presence of sodium acetate. The dye thus obtained forms a red water-soluble powder after drying and dyes wool in vivid red shades with very good fastness properties and good leveling power.
