Description

  

  Verfahren zur Herstellung eines neuen     Kondensationsproduktes.       Es wurde gefunden, dass man ein neues  Kondensationsprodukt erhält, wenn man das  jenige     Tetrachlorpyren,    das durch Chlorieren  des     Pyrens    in Nitrobenzol erhalten wird,  mit     Kondensationsmitteln    behandelt. Das  neue Produkt stellt ein dunkles Pulver dar,  das sich in siedendem     Xylol    mit roter Farbe  und lebhafter grüner Fluoreszenz löst.  



  Das neue Kondensationsprodukt soll zur  Herstellung von     Farbstoffen    verwendet wer  den. So gibt dasselbe durch Behandeln mit  Schwefelsäure einen     Küpenfarbstoff,    der aus  blauer     Küpe    Baumwolle in violetten Tönen  färbt, und mit Salpetersäure einen     Farbstoff,     der Baumwolle aus blaugrüner     Küpe    in  schwarzen Tönen färbt.  



  <I>Beispiel:</I>  1 Teil     Tetrachlorpyren    wie es durch  Chlorieren des     Pyrens    in Nitrobenzol erhalten  wird, wird mit 5 Teilen Aluminiumchlorid    und 1 Teil     Natriumchlorid    4 Stunden auf  <B>130'</B> erhitzt. Die tiefdunkelblaue Schmelze  entwickelt reichlich Chlorwasserstoff. Beim       Zersetzen    mit Wasser entsteht ein dunkel  rotviolettes Produkt, das filtriert und ge  trocknet wird.



  Process for the production of a new condensation product. It has been found that a new condensation product is obtained if the tetrachloropyrene that is obtained by chlorinating the pyrene in nitrobenzene is treated with condensing agents. The new product is a dark powder that dissolves in boiling xylene with a red color and vivid green fluorescence.



  The new condensation product is to be used for the production of dyes who. Thus, by treatment with sulfuric acid, it gives a vat dye which dyes cotton from a blue vat in violet shades, and with nitric acid a dye which dyes cotton from a blue-green vat in black shades.



  <I> Example: </I> 1 part of tetrachloropyrene as obtained by chlorinating pyrene in nitrobenzene is heated to <B> 130 '</B> with 5 parts of aluminum chloride and 1 part of sodium chloride for 4 hours. The deep dark blue melt develops copious amounts of hydrogen chloride. When decomposed with water, a dark red-violet product is formed, which is filtered and dried.
