Description

  

  Zusatzpatent zum Hauptpatent     Nr.    183455.    Verfahren zur Herstellung eines     Azofarbstoffes.       Es wurde gefunden,     dass    man einen     Azo-          farbstoff    erhält, wenn man     diazotiertes        1-          Aminobenzol-3-metliylsulfe,u    in alkalischem  Medium mit     3#,5-Dioxychinolin    vereinigt.  



  Der so erhältliche Farbstoff 'bildet ein  gelbes Pulver, das sieh in Alkohol mit grün  gelber Farbe löst und auf     Acetylzellulose          grünstichiggelbe    Färbungen von guten Echt  heitseigenschaften liefert.  



  <I>Beispiel:</I>  <B>171</B> Teile     1-Aminobenzol-3-metllylsulion     werden in salzsaurer Lösung wie üblich mit  <B>69</B> Teilen     Natriumnitrit        #diazotiert.    Die     Di-          azoläsung        lässt    man in eine     Natriumaoetat     oder     -karbonat    enthaltende Lösung von<B>161</B>  Teilen     3,5-Dic>xychinolin    in der äquivalenten    Menge     Na-#riumllydroxydlös-ung        zutropfen.     Nach beendeter Kupplung wird der Farb  stoff     abfiltriert    und getrocknet.



  Additional patent to main patent No. 183455. Process for the production of an azo dye. It has been found that an azo dye is obtained when diazotized 1-aminobenzene-3-methylsulfe is combined with 3 #, 5-dioxyquinoline in an alkaline medium.



  The dye obtainable in this way forms a yellow powder which dissolves in alcohol with a green-yellow color and provides greenish-yellow colorations with good authenticity properties on acetyl cellulose.



  <I> Example: </I> <B> 171 </B> parts of 1-aminobenzene-3-methylsulion are diazotized with <B> 69 </B> parts of sodium nitrite in a hydrochloric acid solution as usual. The diazole solution is added dropwise to a solution of 161 parts of 3,5-diacinoline in the equivalent amount of sodium hydroxide solution containing sodium acetate or carbonate. After the coupling has ended, the dye is filtered off and dried.

PATENTANSPRUCH: Verfahren zur Herstellung eines Azofarb- stoffes, dadurch gekennzeichnet, dass man diazotiertes 1-Aminebenzol-3-metllylsulion in alkalischem Medium mit 3,5-Dioxycliinolin vereinigt. Der so erhältliche Faxbstoff bildet ein gelbes Pulver, das sich in Alkohol mit grün gelber Farbe löst und auf Acetylzellulose grünstichiggelbe Färbungen von guten Echt- li,eitseigenselia,ftün liefert. Claim: Process for the production of an azo dye, characterized in that diazotized 1-aminebenzene-3-methylsulion is combined with 3,5-dioxycliinoline in an alkaline medium. The fax material obtainable in this way forms a yellow powder which dissolves in alcohol with a green-yellow color and, on acetylcellulose, gives greenish-yellow colorations of good authenticity, purity, and color.
