  Zusatzpatent zum Hauptpatent     Nr.    111564.    Verfahren zur Herstellung eines neuen Farbstoffes.    Es wurde gefunden,     dass    man einen neuen  Farbstoff erhält, wenn man den     Azofarb-          stoff,    welcher durch Kuppeln von     diazotier-          ter        2-Amino-l-phenol-4-sulio,-:#Luxe    mit     Acet-          essig-o-toluidid    erhalten wird, mit     Alkali-          chromit    behandelt.

   Der neue Farbstoff bil  det ein gelbes Pulver, löst sieh in Wasser  mit     oranger    Farbe und färbt Wolle aus     sa--a-          rem    Bade in sehr gleichmässigen, echten  orangen Tönen an.  



  <I>Beispiel:</I>  Zu<B>27</B> Teilen einer     Chroml-iydroxyd-          hydratpaste,    entsprechend 4,4 Teilen     Cr,0,     fügt man allmählich 14 Teile     Ätzkali    und  <B>5</B> Teile Glyzerin und erhitzt die Mischung,  bis alles in Lösung gegangen ist. Sodann  verdünnt man mit<B>25</B> Teilen Wasser, fügt  <B>20,7</B> Teile des Farbstoffes aus     2-Diazo-l-          plienol-4-suliosäure    und     Acetessig-o-toluidid       hinzu und erwärmt     zum    Sieden, bis der  chromhaltige Farbstoff in Lösung gegangen  ist.

   Etwaige     Abseheidungen    von     Chrom.-          o,xyd    werden     abfiltriert,    die Lösung mit Mi  neralsäure neutralisiert und der Farbstoff  mit Kochsalz ausgefällt.



  Additional patent to main patent no. 111564. Process for the production of a new dye. It has been found that a new dye is obtained when the azo dye, which is obtained by coupling diazotized 2-amino-1-phenol-4-sulio, -: # Luxe with acetic-acetic acid-o-toluidide is treated with alkali chromite.

   The new dye forms a yellow powder, dissolves in water with an orange color and dyes wool from acidic baths in very even, genuine orange tones.



  <I> Example: </I> To <B> 27 </B> parts of a chromium hydroxide hydrate paste, corresponding to 4.4 parts of Cr.0, gradually add 14 parts of caustic potash and <B> 5 </B> Part glycerine and heat the mixture until everything has dissolved. It is then diluted with 25 parts of water, 20.7 parts of the dye composed of 2-diazo-l-plienol-4-sulioic acid and acetoacetic-o-toluidide are added and the mixture is heated to boiling until the chromium-containing dye has gone into solution.

   Any deposits of chromium o, xyd are filtered off, the solution is neutralized with mineral acid and the dye is precipitated with sodium chloride.
