Description

  

  Verfahren zur Herstellung eines sauren     Wollazofarbstoffes.       Vorliegendes Patent bezieht sich auf ein  Verfahren zur Herstellung     eines    sauren       W        ollazofarbstoffes,    dadurch gekennzeichnet,  dass. man     diazotiertes        1-(N-Aoetyl-s,ec.-.butyl-          amino)-4-aminobenzol    in     essigsaurem        Me-          dium    mit     2,-Ben7,oylamino-5-naphthol-7=sul-          f        onsäure    kuppelt.  



  Der so erhaltene Farbstoff     bildet    nach  dem Trocknen ein gelbrotes, wasserlösliches       Pulver    und färbt Wolle und     Seide    in     leuch-          tend    orangen Tönen von sehr gutem     E.gadi-          siervermögen    und guten     Echtheitseigen-          schaften.     



  <I>Beispiel:</I>  20,6 Teile     1-(N-Acetyl-sec.-butylamino)-          4-aminobenza1    werden in der üblichen     Weise          diazotiert.    Die erhaltene     Diazolösung    lässt  man in eine mit überschüssigem     Natrium-          aoetat        versetzte    Lösung von 3,6 Teilen       2-Benzoylamino-5-naphthol-7-sulfonsäure    ein-         laufen.    Nach     beendeter        Kupplung        wird        der     Farbstoff abgeschieden und getrocknet.



  Process for the preparation of an acidic wool azo dye. The present patent relates to a process for the production of an acidic wool azo dye, characterized in that diazotized 1- (N-aoetyl-s, ec .-. Butyl-amino) -4-aminobenzene in acetic acid medium with 2, -Ben7, oylamino-5-naphthol-7 = sulphonic acid.



  The dyestuff obtained in this way forms a yellow-red, water-soluble powder after drying and dyes wool and silk in bright orange shades with very good E.gadizability and good fastness properties.



  <I> Example: </I> 20.6 parts of 1- (N-acetyl-sec.-butylamino) -4-aminobenza1 are diazotized in the usual way. The diazo solution obtained is allowed to run into a solution of 3.6 parts of 2-benzoylamino-5-naphthol-7-sulfonic acid to which excess sodium acetate has been added. When the coupling is complete, the dye is deposited and dried.

PATENTANSPRUCH: Verfahren zur Herstellung eines sauren Wollazofarbstoffes, dadurch gekennzeichnet, ,dass@ man idiazotiertes 1-(N-Aoetyl-sec.-butyl- amäno)-4-aminobenzol in essigsaurem Me dium mit 2-Benzoylamino-5-naphthol-7-sul- fonsäure kuppelt. PATENT CLAIM: Process for the production of an acidic wool azo dye, characterized in that @ one idiazotized 1- (N-aoetyl-sec.-butyl-amano) -4-aminobenzene in acetic acid medium with 2-benzoylamino-5-naphthol-7- sulphonic acid couples. Der so erhaltene Farbstoff bildet nach dem Trocknen ein gelbrotes, wasserlösliches Pulver und färbt Wolle und Seide in leuch tend orangen Tönen von sehr gutem EgaJs- siervermögen und guten Echtheitseigen- schaften. The dye obtained in this way forms a yellow-red, water-soluble powder after drying and dyes wool and silk in bright orange shades with very good gasifying power and good fastness properties.
