  Verfahren zur Herstellung von   Schwefelfarbstoffen.   



   In dem Patente Nr. 56760 wird ein'Verfahren beschrieben, nach welchem aus Perimidin oder dessen Derivaten durch Kondensation mit Chinonchlorimid oder durch Zusammenoxydieren mit Aminophenol usw. neue Indophenole erhalten werden. Es hat sich nun gezeigt, 
 EMI1.1 
   sehen, die sich   durch eine schöne grüne Nuance und durch grosse Echtheit auszeichnen. Zur Darstellung dieser   SchwefelfarbstoSe   verfährt man beispielsweise wie folgt. 



   In ein Gemisch von 70 Teile Alkohol, 40 Teile einer 22% Na2 S enthaltenden Schwefel-   natriumlösung   mit 13 Teilen Schwefel werden   17#1   Teile des aus 2. 6-Dichlor-p-aminophenol und Perimidin erhaltenen Indophenols eingetragen. Die Masse wird etwa 60 Stunden am   Rucknusskühler gekocht,   darauf der Alkohol abdestilliert und der Rückstand mit Wasser verdünnt. Der grösste Teil des gebildeten Farbstoffes bleibt alsdann ungelöst als   grünschwarzes   Pulver zurück,   während   der Rest aus den   Lösungen   durch Ausblasen isoliert werden kann. 



  Der so erhaltene Farbstoff erzeugt aus schwefelnatriumhaltigem Bade auf Baumwolle ein dunkles echtes   Grün.   



   An Stelle des im vorstehenden Beispiel verwendeten   Indophenols kann man sich anderer     aus   Perimidin oder seinen Derivaten entstehender Indophenole bedienen. Die Ausführung des 
 EMI1.2 
 des Alkohols em anderes Lösungsmittel verwenden ; andererseits kann man auch die Reaktion in   Gegenwart von Glyzerin durchführen.   



   Endlich kann man sich zur   Durchführung   des   Schwefelungsprozesses auch anderer   Alkalipolysulfide und insbesondere der höher geschwefelten Sulfide bedienen.

  Process for the production of sulfur dyes.



   Patent No. 56760 describes a process according to which new indophenols are obtained from perimidine or its derivatives by condensation with quinone chlorimide or by oxidizing together with aminophenol, etc. It has now been shown
 EMI1.1
   see, which are characterized by a beautiful green shade and great authenticity. To represent this sulfur color, one proceeds, for example, as follows.



   17 parts of the indophenol obtained from 2,6-dichloro-p-aminophenol and perimidine are introduced into a mixture of 70 parts of alcohol, 40 parts of a sodium sulphide solution containing 22% Na 2 S with 13 parts of sulfur. The mass is boiled for about 60 hours on a walnut cooler, then the alcohol is distilled off and the residue is diluted with water. Most of the dye formed then remains undissolved as a green-black powder, while the remainder can be isolated from the solutions by blowing out.



  The dye obtained in this way produces a dark, true green from a bath containing sodium sulphide on cotton.



   Instead of the indophenol used in the above example, other indophenols formed from perimidine or its derivatives can be used. The execution of the
 EMI1.2
 use a different solvent of the alcohol; on the other hand, the reaction can also be carried out in the presence of glycerol.



   Finally, other alkali polysulphides and in particular the more highly sulphurized sulphides can also be used to carry out the sulphurisation process.
