Description

  

      Zusatzpatent    zum Hauptpatent Nr. 114283.         'Verfahren    zur Herstellung eines     neuen        Farbstoffes.       Es wurde gefunden, dass man einen  neuen Farbstoff erhält, wenn man die  jenige     ss-Naphthylbarhitursäure,    welche aus       ss-Naphtliylharnstoff    und     Malonester    erhal  ten wird, mit     diazotierter        4-Chlor-2-amino=          1.-phenol-5-sulfosäure    kuppelt und das so  erhaltene Produkt mit     Fluorchrom    be  handelt.

   Der neue Farbstoff bildet ein       orangebraunes    Pulver, löst sich in verdünn  1er     Sololösung    mit oranger Farbe und erzeugt       iiuf    Wolle, aus saurem Bade gefärbt, echte  rotbraune Töne.  



       Beispiel:          224    Teile     4-Chlor-2-amino-l-plienol-5-          Sulfosäure    werden wie üblich     diazotiert     und in ein Gemisch aus 267 Teilen     ss-          Naphthylbarbitursäure,        133    Teilen 30     %iger     Natronlauge, 170 Teilen Soda und 1500 Tei  len Wasser eingetragen. Die Kupplung setzt  sofort ein; zu ihrer Vervollständigung rührt       nian    noch einige Zeit.

   Der gebildete     Farb-          4off    wird dann filtriert und     getrocknet.       50,2 Teile dieses Farbstoffes werden in  650 Teilen kochendem Wasser gelöst und  mit einer     Fluorchromlösung,    entsprechend  15,2 Teilen     Cr203,    versetzt. Man kocht  mehrere     Stunden    am     Rückflusskühler,    dampft  teilweise ein und gewinnt die neue Chrom  verbindung durch Filtrieren, gegebenenfalls       unter    vorherigem     Aussalzen.  



      Additional patent to main patent No. 114283. Process for the production of a new dye. It has been found that a new dye is obtained if the one ss-naphthylbarhituric acid, which is obtained from ss-naphthylurea and malonic ester, is coupled with diazotized 4-chloro-2-amino = 1.-phenol-5-sulfonic acid and the product thus obtained is treated with fluorochrome be.

   The new dye forms an orange-brown powder, dissolves in a dilute solo solution with an orange color and produces genuine red-brown tones on wool, dyed from an acid bath.



       Example: 224 parts of 4-chloro-2-amino-l-plienol-5-sulfonic acid are diazotized as usual and introduced into a mixture of 267 parts of ss-naphthylbarbituric acid, 133 parts of 30% sodium hydroxide solution, 170 parts of soda and 1500 parts of water . The clutch works immediately; it will take some time to complete it.

   The dye formed is then filtered and dried. 50.2 parts of this dye are dissolved in 650 parts of boiling water and a fluorochrome solution, corresponding to 15.2 parts of Cr 2 O 3, is added. It is boiled for several hours on the reflux condenser, partially evaporated and the new chromium compound is obtained by filtration, if necessary with prior salting out.
