Description

  

      Zusatzpatent    zum Hauptpatent Nr. 127259.    .     Verfahren    zur Herstellung eines neuen     Farbstoffes.       Es wurde gefunden, dass man einen neuen  Farbstoff erhält, wenn man     diazotierte        4-          Benzoylamino-2-amino-l-benzolsulfosäure    mit       1-Phenyl-3-methyl-5-pyrazolon    kuppelt. Der  so erhaltene Farbstoff bildet ein gelbes Pul  ver. Er färbt Wolle aus schwefelsaurem  Bade in sehr gleichmässigen, rotgelben Tönen.  Die Färbungen sind sehr gut licht-,     wasser-,     wasch- und     alkaliecht    und halten der sauren  Walke stand.  



       Beispiel:     17,4 Teile     1-Phenyl-3-methyl-5-pyrazolon     werden in 150 Teilen Wasser mit 20 Teilen       calcinierter    Soda und der nötigen Menge  Natronlauge gelöst, mit Eis gekühlt und hier  auf mit der     Diazoverbindung    aus 29,2 Teilen       #1-        Benzoylamino-    2-     amino        -1-benzolsulf        osäure     versetzt. Der sich bildende Farbstoff scheidet    sich teilweise aus. Durch Zusatz von Koch  salz wird die Fällung vervollständigt, dann  wird möglichst     neutral    gestellt, filtriert und  getrocknet.



      Additional patent to main patent No. 127259.. Process for the production of a new dye. It has been found that a new dye is obtained when diazotized 4-benzoylamino-2-amino-1-benzenesulfonic acid is coupled with 1-phenyl-3-methyl-5-pyrazolone. The dye thus obtained forms a yellow powder. It dyes wool from a sulfuric acid bath in very even, red-yellow tones. The dyeings are very light, water, wash and alkali-fast and withstand acidic milled wool.



       Example: 17.4 parts of 1-phenyl-3-methyl-5-pyrazolone are dissolved in 150 parts of water with 20 parts of calcined soda and the necessary amount of sodium hydroxide solution, cooled with ice and then mixed with the diazo compound from 29.2 parts of # 1 - Benzoylamino 2- amino -1-benzenesulfonic acid added. The dye that forms is partially separated out. The precipitation is completed by adding sodium chloride, then it is made as neutral as possible, filtered and dried.

PATENT CLAIM: Process for the preparation of a new dye, characterized in that diazotized 4-benzoylamino-2-amino-1-benzenesulfonic acid is coupled with 1-phenyl-3-methyl-5-pyrazolone. The dye obtained in this way forms a yellow powder. He dyes wool from sulfuric acid bath in very even, red-yellow tones. The dyeings are very fast to light, water, wash and alkali and withstand acidic fulling.
