Description

  

  Verfahren zur Herstellung eines neuen metallhaltigen     Farbstoffes.       Es wurde gefunden, dass man einen neuen  metallhaltigen Farbstoff erhält, wenn man  das Kupplungsprodukt aus     diazotiertem        4-          Chlor-2-amino-l-phenol    und     1-Oxynaphtha-          lin-3,8-disulfosäure    mit     Fluorchrom    behan  delt. Der neue metallhaltige Farbstoff bil  det ein dunkles Pulver, löst sich in Wasser  mit violetter, in verdünnter Natronlauge mit  rotvioletter Farbe und erzeugt auf Wolle,  aus saurem Bade gefärbt, rotblaue Töne.

    <I>Beispiel</I>  45,8 Teile des Farbstoffes aus     diazotier-          tem        4-Chlor-2-amino-l-phenol    und     1-Oxy-          naphthalin-3,8-disulfosäure    werden in 1500  Teilen Wasser kochend gelöst, mit einer       Fluorchromlösung    entsprechend 20. Teilen  Chromoxyd versetzt und so lange unter Zu  satz von Glaspulver am     Rückflusskühler     gekocht, bis sich der chromhaltige Farb-         stoff    gebildet hat.

   Die     Farbstofflösung    wird  hierauf etwas eingedampft und der- neue  Farbstoff durch     Kristallisierenlassen    oder  durch     Aussalzen    gewonnen. -



  Process for the production of a new metal-containing dye. It has been found that a new metal-containing dye is obtained if the coupling product of diazotized 4-chloro-2-amino-1-phenol and 1-oxynaphthalin-3,8-disulfonic acid is treated with fluorochrome. The new metal-containing dye forms a dark powder, dissolves in water with a violet color, in dilute sodium hydroxide solution with a red-violet color and produces red-blue tones on wool dyed from an acid bath.

    <I> Example </I> 45.8 parts of the dye from diazotized 4-chloro-2-amino-1-phenol and 1-oxynaphthalene-3,8-disulfonic acid are dissolved in 1500 parts of boiling water with a fluorochrome solution corresponding to 20 parts of chromium oxide and boiled with the addition of glass powder on the reflux condenser until the chromium-containing dye has formed.

   The dye solution is then slightly evaporated and the new dye is obtained by letting it crystallize or by salting out. -

PATENTANSPRUCH: Verfahren zur Herstellung eines neuen metallhaltigen Farbstoffes, dadurch gekenn zeichnet, dass man das Kupplungsprodukt aus diazotiertem 4-Chlor-2-amino-l-phenol und 1-Oxynaphthalin-3,8-disulfosäure mit Fluorchrom behandelt. Der neue metallhal tige Farbstoff bildet ein dunkles Pulver, löst sich in Wasser mit violetter, in ver dünnter Natronlauge mit rotvioletter Farbe und erzeugt auf Wolle, aus saurem Bade gefärbt, rotblaue Töne. PATENT CLAIM: A process for the production of a new metal-containing dye, characterized in that the coupling product of diazotized 4-chloro-2-amino-1-phenol and 1-oxynaphthalene-3,8-disulfonic acid is treated with fluorochrome. The new metal-containing dye forms a dark powder, dissolves in water with a violet color, and in dilute caustic soda with a red-violet color and produces red-blue tones on wool dyed from an acidic bath.
