Description

  

  <B>Zusatzpatent</B> zum Hauptpatent Nr. 1865.50.    Verfahren zur Herstellung eines neuen     Azofarbstoffes.       Es wurde gefunden, dass man einen neuen       Azofarbstoff    erhält, wenn man     diazotiertes          I-Aminobenzol-2,4-#di-(diäthyls#ulfamid)        mit     dem 2,8 -     Oxynaphthoesäure    - 2' -     methoxy    - 5'  ehloranilid vereinigt.  



  Der neue Farbstoff stellt einen roten Nie  derschlag dar. Auf geeigneten Substraten,  wie z. B. Baumwolle, hergestellt, färbt er  diese in orangen Tönen von sehr guten Echt  heitseigenschaften.  



       Beispiel:     30     Teile        1-Aminobenzol-2,4-:di-(diKthyl-          sulfamid)    werden wie üblich     diazotiert    und  in eine Lösung von 32,7 Teilen     2,3-Oxynaph-          thoesäure-2'-methoxy-5'-chloranilid,    50 Teilen  30%iger Natronlauge, 30 Teilen Soda und    2000 Teilen Wasser eingetragen. Der gebil  dete Farbstoff fällt sofort aus. Der rote Nie  derschlag wird filtriert und getrocknet.



  <B> Additional patent </B> to main patent No. 1865.50. Process for the production of a new azo dye. It has been found that a new azo dye is obtained when diazotized 1-aminobenzene-2,4- # di- (diethyls # sulfamide) is combined with 2,8-oxynaphthoic acid-2'-methoxy-5'-chloranilide.



  The new dye represents a red precipitate. On suitable substrates, such as. B. cotton, produced, he dyes these in orange tones of very good authenticity properties.



       Example: 30 parts of 1-aminobenzene-2,4-: di- (di-ethylsulfamide) are diazotized as usual and dissolved in a solution of 32.7 parts of 2,3-oxynaphthoic acid-2'-methoxy-5'-chloroanilide , 50 parts of 30% sodium hydroxide solution, 30 parts of soda and 2000 parts of water entered. The formed dye precipitates immediately. The red precipitate is filtered and dried.
