Description

  

  Verfahren zur Herstellung eines     Küpenfarbstoffes    der     Pyranthronreihe.       Es wurde gefunden,     dass    man einen neuen       Küpenfarbstoff    der     Pyranthronreihe    erhält,  wenn man das     Trichlorpyrantliron,    das er  halten werden kann nach den Angaben des  Beispiels<B>3</B> des<B>D.</B>     R.    P.     Nr.        2181#62,    mit  Phenol in Gegenwart von     Alkalikarbonat     kondensiert.  



  Der erhaltene Farbstoff bildet ein orange  rotes Pulver, welches Baumwolle aus schar  lachroter     Küpe    in echten, sehr reinen, feu  rigen, roten Tönen färbt. Das neue Produkt  löst sich mit blauroter Farbe in konzentrier  ter Schwefelsäure, in Wasser gegossen schei  den aus dieser Lösung orangerote Flocken  aus. In siedendem     Xylol    löst es sich mit gel  ber Farbe und schwacher gelbgrüner Fluo  reszenz; in siedendem Nitrobenzol orange  rot mit schwach gelbgrüner Fluoreszenz; in  Anilin mit orangeroter Farbe.    <I>Beispiel:</I>    <B>100</B> Teile Phenol werden mit<B>5</B> Teilen  Natriumkarbonat versetzt und zum Vertrei  ben des Wassers aus der Mischung 'kurze Zeit  im Sieden erhalten.

   Hierauf     lässt    man ab-    kühlen, versetzt mit<B>5</B> Teilen     Trielilorpyr-          anthron    (welches zweckmässig nach Beispiel  <B>3</B> des<B>D.</B>     R.    P.     Nr.   <B>2,18162</B> hergestellt worden  ist) und erhitzt einige Stunden -zum Sieden.  Während des     Siedeus    tritt langsam Farben  umschlag von orange nach orangerot ein und  der neue Farbstoff scheidet sich aus. Hier  auf     lässt    man abkühlen, versetzt mit 200 Tei  len Alkohol,     filtriert    den     ausgesehiedenen     Farbstoff ab,     wäselit    ihn mit heissem Wasser  und trocknet ihn.



  Process for the production of a vat dye of the pyranthrone series. It has been found that a new vat dye of the pyranthrone series is obtained if the trichloropyrantlirone, which it can be obtained from, is obtained according to the information in Example 3 of the D. RP No. 2181 # 62, condensed with phenol in the presence of alkali carbonate.



  The dye obtained forms an orange-red powder which dyes cotton from a sharp, laugh-red vat in real, very pure, fiery red tones. The new product dissolves in concentrated sulfuric acid with a blue-red color; when poured into water, orange-red flakes separate from this solution. It dissolves in boiling xylene with a yellow color and a weak yellow-green fluorescence; in boiling nitrobenzene orange red with pale yellow-green fluorescence; in aniline with an orange-red color. <I> Example: </I> <B> 100 </B> parts of phenol are mixed with <B> 5 </B> parts of sodium carbonate and boiled for a short time to drive the water out of the mixture.

   It is then allowed to cool, mixed with <B> 5 </B> parts of Trielilorpyranthron (which is expediently according to example <B> 3 </B> of <B> D. </B> RP No. <B> 2,18162 </B>) and heated to boiling for a few hours. During the boiling process, the color slowly changes from orange to orange-red and the new dye separates out. Here it is allowed to cool, 200 parts of alcohol are added, the dye that has separated out is filtered off, washed with hot water and dried.
