  Zusatzpatent zum     Ilauptpatent        Nr.   <B>97059.</B>    Verfahren zur Darstellung eines als Farbstoff und     Farbstoffzwischenprodukt     verwendbaren     K.ondensationsproduktes    der     Anthrachinonreihe.       Es wurde gefunden,     dass    man ein neues,  als Farbstoff und     Farbstoffzwiselienproduk##     verwendbares Kondensationsprodukt der     An-          t-hra,e,Iiino#nreihe    erhält, wenn man     Cyanur-          ehlorid    und     Anthra,rhino#n-4-a.mino-4'-chlor-          2,

  1-thioxalithon    aufeinander einwirken     lässt,     und zwar im ungefähren Verhältnis von  2 Molekülen des letzteren auf<B>1</B> Molekül des  ersteren. Das neue     KondensationsproJukt     bildet ein braunviolettes Pulver, löst sich in  konzentrierter Schwefelsäure mit     roterFarbe     und gibt mit     Hydrosulfit        und        Natro-nlauge     eine violette     Kripe,    aus welcher Baumwolle  sehr licht,     waseh-,        bäuch-        und        ehloreeht    rot  violett gefärbt wird.

  Additional patent to main patent no. <B> 97059. </B> Process for the preparation of a condensation product of the anthraquinone series which can be used as a dye and dye intermediate. It has been found that a new condensation product of the ant-hra, e, iino-series which can be used as a dye and dyestuff intermediate product is obtained when cyanuric chloride and anthra, rhino-4-a.mino-4 '-chlor- 2,

  1-thioxalithone can act on each other, in the approximate ratio of 2 molecules of the latter to <B> 1 </B> molecule of the former. The new condensation product forms a brown-violet powder, dissolves in concentrated sulfuric acid with a red color and, with hydrosulphite and sodium hydroxide solution, gives a violet cripe, from which cotton is dyed very light, waseh-, tummy- and ehlore-light red-violet.

      <I> Example: </I> <B> 39 </B> parts of ant-, liraehinoli-4-amino-4-chloro-2,1-thioxanthone in <B> 500 </B> parts of nitrobenzene registered and offset with <B> 9.3 </B> parts Cya, - nurchlorid. 7t. The mixture is then gradually heated to the boiling point of the nitrobenzene while stirring and stirring is continued for a few hours at this temperature.

   The cooled reaction liquid is filtered, the residue is washed with nitrobenzene and alcohol and dried.
