Description

  

  Verfahren     zur    Darstellung eines     Küpenfarbstoffes    der     Anthrachinonreihe.       Es wurde     gefunden,    dass man zu einem  neuen wertvollen     Küpenfarbstoff    der     Anthra-          chinonreihe    gelangt,     wenn    man das Ein  wirkungsprodukt von     1-Amino-2-oxyanthra-          chinon    auf ein solches     1-Aminoanthrachinon,     das in     2-Stellung        einen,Substituenten    besitzt,  der befähigt ist,

   das zur Bildung     eines          Oxazolringes    erforderliche     ,u-gohlenstoff-          atom    zu liefern, durch Erhitzen kondensiert.  Dies kann beispielsweise     in    der Weise ge  schehen,     da.B    man     zuersü        1-Amino-2-oxy-          anthrachinon    und zum Beispiel     1,2-Amino-          anthrachinonaldehyd    in     Gegenwart    eines  indifferenten     Verdünnungsmittels    zusam  menbringt und darauf die Reaktionslösung  zum Sieden erhitzt.

   Statt des     1,2-Amino-          anthrachinona.Idehyds    kann man auch zum  Beispiel das     1,2-Aminoanthrachinoncarbon-          säurechlorid    verwenden, sowie Substanzen,  die während der Reaktion in den entspre  chenden Aldehyd     bezw.    das entsprechende  Säurederivat übergehen können.

   Der neue  Farbstoff, der sich in     Schwefelsäure    mit  oliver Farbe löst und eine hervorragende    Affinität zur Faser     besitzt,    färbt Baum  wolle aus     violettstichig    roter     Hydrosulfit-          küpe    in gleicher Farbe an und geht nach  der Oxydation in ein sehr echtes, blau  stichiges Rot über.  



  <I>Beispiel</I>  1 Teil     1-Aminoanthrachinon-2-carbon-          säurechlorid    und     1-Amino-2-oxyanthrachi-          non    werden in 10 Teilen Nitrobenzol eine       Stunde    lang auf 120 bis<B>130'</B> erhitzt, wo  bei sich vorübergehend ein     Einwirkungs-          produkt        bildet,    welches das zur Bildung  eines     Oxazolringes    erforderliche     ,u-gohlen-          stoffatom    enthält;

   darauf     wird    die Tempera  tur     allmählich    zum Sieden gesteigert und  das Gemisch so lange im Sieden erhalten,  bis eine weitere     Farbstoffbildung    nicht  mehr zu bemerken ist. Nach dem Erkalten  wird der Farbstoff abgesaugt.



  Process for the preparation of a vat dye of the anthraquinone series. It has been found that one arrives at a new valuable vat dye of the anthrachinone series, if one has the effect product of 1-amino-2-oxyanthraquinone on such a 1-aminoanthraquinone, which has a substituent in the 2-position is capable

   the u-carbon atom required to form an oxazole ring is condensed by heating. This can be done, for example, in such a way that zuersü 1-amino-2-oxy-anthraquinone and, for example, 1,2-amino-anthraquinone aldehyde are brought together in the presence of an inert diluent and the reaction solution is then heated to the boil.

   Instead of the 1,2-amino anthraquinone.Idehyde, for example, the 1,2-aminoanthraquinone carbonic acid chloride can also be used, as well as substances that are converted into the corresponding aldehyde during the reaction. the corresponding acid derivative can pass over.

   The new dye, which dissolves in sulfuric acid with an olive color and has an excellent affinity for fibers, dyes cotton from a purple-tinged red hydrosulfite vat in the same color and, after oxidation, turns into a very real, blue-tinged red.



  <I> Example </I> 1 part of 1-aminoanthraquinone-2-carboxylic acid chloride and 1-amino-2-oxyanthraquinone are heated in 10 parts of nitrobenzene to 120 to 130 'for one hour where a product of action temporarily forms which contains the u-carbon atom required for the formation of an oxazole ring;

   then the temperature is gradually raised to boiling and the mixture is kept boiling until further dye formation is no longer noticeable. After cooling, the dye is suctioned off.
