Description

  

  Verfahren zur Herstellung eines neuen     Farbstoffes.       Es wurde gefunden, dass man einen neuen  Farbstoff erhält, wenn man     2,5-Di-,B-naph-          thylaminobenzochinon    mit einer Lösung von  Chlor in     Schwefeldichlorid,    entsprechend der       Zusammensetzung        SC14,    und zwar im Ver  hältnis von 1     Mol.        2,5-Di-,B-naphthylamino-          benzochinon    zu 2     Mol.        SC14,    behandelt.

   Der  neue Farbstoff bildet ein gelbbraunes Pul  ver, das sich in konzentrierter Schwefelsäure  mit rotbrauner Farbe und Wolle aus der       Küpe    gelbbraun färbt.    <I>Beispiel:</I>  3,9 Teile     2,5-Di-B-naphthyla,minobenzo-          ehinon    werden in einem Gemisch von 33 Tei  len     Nitrobenzol    und 66 Teilen     o-Nitrotoluol     suspendiert und unter starker Kühlung mit  einer Lösung von Chlor in     Schwefeldichlorid,     entsprechend der Zusammensetzung     SC14,       versetzt. Nach einiger Zeit wird der neue  Farbstoff filtriert, mit Alkohol nachgewa  schen und getrocknet.



  Process for the production of a new dye. It has been found that a new dye is obtained when 2,5-di-, B-naphthylaminobenzoquinone is mixed with a solution of chlorine in sulfur dichloride, corresponding to the composition SC14, in a ratio of 1 mol. 2.5 -Di-, B-naphthylamino-benzoquinone to 2 mol. SC14 treated.

   The new dye forms a yellow-brown powder that turns yellow-brown in concentrated sulfuric acid with red-brown color and wool from the vat. <I> Example: </I> 3.9 parts of 2,5-di-B-naphthyla, minobenzo- ehinon are suspended in a mixture of 33 parts of nitrobenzene and 66 parts of o-nitrotoluene and with strong cooling with a solution of Chlorine is added to sulfur dichloride according to the composition SC14. After a while, the new dye is filtered, rewashed with alcohol and dried.

PATENTANSPRUCH: Verfahren zur Herstellung eines neuen Farbstoffes, dadurch gekennzeichnet, daB man 2,5-Di-ss-naphthylaminobenzochinon mit einer Lösung von Chlor in Schwefeldichlo- rid, entsprechend der Zusammensetzung SCl4, und zwar im Verhältnis von 1 Mol. 2,5-Di- fl-naphthylaminobenzochinon zu 2 Mol. SC14, behandelt. PATENT CLAIM: Process for the production of a new dye, characterized in that 2,5-di-ss-naphthylaminobenzoquinone is mixed with a solution of chlorine in sulfur dichloride, corresponding to the composition SC14, in a ratio of 1 mol. 2.5- Di-fl-naphthylaminobenzoquinone to 2 mol. SC14 treated. Der neue Farbstoff bildet ein gelbbraunes Pulver, das sich in konzen trierter Schwefelsäure mit rotbrauner Farbe löst und Wolle aus der Küpe gelbbraun färbt. The new dye forms a yellow-brown powder that dissolves in concentrated sulfuric acid with a red-brown color and dyes wool from the vat yellow-brown.
