  Verfahren zur Herstellung eines     Farbstoffes    der     Phtbaloeyaninreibe.       Es     wurdegefunden,        dass#    man einen neuen  wertvollen Farbstoff der     Plitaloryaninreihe     erhält, wenn man 4 .4'.<B>g".</B>     g"-TotTachlor-          kupf,erpliäaloeya,nin    mit     p-Thiokr-esol    um  setzt.  



  Man kann das     Thiokresol    auch in Form  seiner     Alkalimetallverbindungen    verwenden.  Mit Vorteil verwendet man Verdünnungs  mittel mit.<B>Als,</B> solches kann ein     Überschuss     des     Thiokresolsdienen    oder auch     Naplithalin,     ein     AI'kyluaplithalin    oder ein aromatischer       Nitrokohlenwasiserstoff.    Man kann die Um  setzung auch     un#tererhöhtem    Druck ausfüh  ren, wobei man als     Verdünnungsmittel        ter-          t.i5,re    Basen, wie     Pyridin    oder     Chinolin,

      oder  aromatische     Kohlenwasserstoffe    (Benzol,     To-          luoil,        Xylol)    benutzt. Man kann dem     Um-          setzungsgemisell    auch geringe Mengen von  Metallen, z. B. Kupfer, zusetzen, die den     Ha-          logenaustaus:ch    beschleunigen.  



  Der neue Farbstoff ist     bläuliell    grün. Er    kann zum Beispiel als Körperfarbstoff ver  wendet werden.  



  <I>Beispiel:</I>  <B>5,0</B> Teile 4. 4'.<B>9'.</B>     4"'-Tetraz#hlorkupfer-          ph,tli-aloeya,n#in    werden mit<B>38,5</B> Teilen     p-          Thiokresol,   <B>17</B> Teilen gemahlenem     Kalium-          Ily,droxyd,   <B>1</B> Teil Kupfermehl und<B>50</B> Teilen       Xylol    in einem geschlossenen Gefäss<B>-15</B>     Ston-          den    lang auf<B>3,50 ' C</B> erhitzt. Nach dem Ver  dünnen mit     Xylol    wird der Farbstoff ab  gesaugt, mit Alkohol gut ausgewaschen, mit       verdünüter    Salzsäure ausgekocht und neutral  gewaschen.

   Nach     dem    Trocknen wird der  Farbstoff zur weiteren Reinigung in     ider     achtfachen Menge     Chlorsulfonsäure    gelöst,  die Lösung in<B>5,0 ' C</B> warmes     Wasiser    einge  gossen, der Farbstoff abgesaugt, neutral ge  waschen, Spuren von noch  haftender       Sä,ure    mit Ammoniak entfernt und getrock  net. Der Farbstoff     ietbläuliehgrüu.    In hoch-      siedenden Lösungsmitteln ist er etwas lös  lich, und zwar mit blaugrüner Farbe.



  Process for the preparation of a dye of phtbaloeyanine rub. It has been found that # a new valuable dye of the plitaloryanine series is obtained if one reacts 4 .4 '. <B> g ". </B> g" -TotTachlor- kupf, erpliäaloeya, nin with p-thiocr-esol.



  The thiocresol can also be used in the form of its alkali metal compounds. It is advantageous to use diluents with. An excess of thiocresol or naplithalin, an alkyluaplithalin or an aromatic nitrohydrogen can serve as such. The reaction can also be carried out under increased pressure, in which case the diluent used is a basic one such as pyridine or quinoline,

      or aromatic hydrocarbons (benzene, toluil, xylene) are used. You can add small amounts of metals, z. B. copper, which accelerate the halogen exchange: ch.



  The new dye is bluish green. For example, it can be used as a body pigment.



  <I> Example: </I> <B> 5.0 </B> parts 4. 4 '. <B> 9'. </B> 4 "'- Tetraz # hlorkupfer- ph, tli-aloeya, n #in is used with <B> 38.5 </B> parts p-thiocresol, <B> 17 </B> parts ground potassium ily, droxyd, <B> 1 </B> part copper flour and <B> 50 </B> Divide xylene in a closed vessel <B> -15 </B> Stands heated to <B> 3.50 'C </B>. After thinning with xylene, the dye is sucked off, Washed out well with alcohol, boiled with dilute hydrochloric acid and washed neutral.

   After drying, the dye is dissolved in eight times the amount of chlorosulfonic acid for further cleaning, the solution is poured into <B> 5.0 'C </B> warm washer, the dye is suctioned off, washed neutral, traces of still adhering seed, ure removed with ammonia and dried. The dye ietbläuliehgüu. It is somewhat soluble in high-boiling solvents, with a blue-green color.
