  Verfahren zur Darstellung eines neuen Kondensationsproduktes.    Im Hauptpatent ist ein Verfahren zur       Dafstellung    eines neuen     Kondensationspro-          .duktes,        da--s    aus     orangefarbener        Küpe    Baum  wolle in der gleichen Farbe anfärbt und  beim     Verhämgen    an der Luft ein     grünsti-          chi,ges        Gelh    liefert, das     heiln,    Betupfen mit  Alkali     najcll    Rot umschlägt, beschrieben,

   bei  dem     Anthrapyrimidon    mit alkalischen Kon  densationsmitteln behandelt wird.  



  <B>Es</B> wurde nun gefunden,     dass    man bei der  Behandlung von     Antlirapyrimidin    mit alka  lischen Mitteln ein ähnliches neues     Konden-          sationsproaukterhält.    Dieses     haundurch    Be  handeln mit oxydierenden Mitteln gereinigt  werden.

   Das neue     Kondensatio-nsprodukt    ist  ein wertvoller     Küpenfa.rb#stdi;    es kristalli  siert aus     Trichlorbenzal    in     gelbgränen    Na  deln und     febt    aus brauner     Küpe    Baumwolle  in der gleichen Farbe; die     FIrbung    lief     ert     beim     Verhängen    an der Luft ein     grünstichi-          ,        1.   <B>c</B>       geA,        hlor-    und     seifenech-üsss    Gelb.

Der Farbstoff  kann     durüh    Behandeln mit oxydierenden     Mit-          teln,    zum Beispiel Erhitzen mit     Hypoohlorit-          lösung,    gereinigt werden.

  Process for the preparation of a new condensation product. In the main patent is a process for producing a new condensation product that dyes cotton in the same color from an orange vat and, when it is kneaded in the air, produces a greenish gel that heals, dabbing with alkali, najcll Turns red, written on,

   in which anthrapyrimidone is treated with alkaline condensation agents.



  It has now been found that a similar new condensation process is obtained when antlirapyrimidine is treated with alkaline agents. This can be cleaned by treating with oxidizing agents.

   The new condensation product is a valuable vat fa.rb # stdi; it crystallizes from trichlorobenzal in yellow-green needles and wicks cotton of the same color from a brown vat; When hanging in the air, the color gives a green tinge, 1. <B> c </B> yellow, halo and soapy yellow.

      <I> Example: </I> <B> 10 </B> parts of anthrapyrimid-yne (obtained according to <B> D. </B> RP 220314 by the action of formami, cl on a-aminoa # nthrachin-one ) are entered into a melt obtained by heating <B> 100 </B> parts of potassium hydroxide and <B> 100 </B> parts of alcohol at <B> 130 '</B>.

   The temperature is then increased to 140 and held until the dye formation has ended; the dead brown melt is poured into water, the leuco compound is oxidized with air and the dye is worked up in the usual way. The dye can be cleaned by treating it with oxidizing agents, for example heating with hypochlorite solution.
