Description

  

  Verfahren zur Darstellung eines     hochchlorierten,        stickstoffhaltigen,          hydroaromatischen    Produktes.    Es wurde gefunden, dass man beim Chlo  rieren des salzsauren Salzes von     P-Arriiiro-          anthrachinon    in     einem    irrdifferenten     Suspen-          sionsmittel,    das keine Hydrolyse zustande       kommen        läfit    und bei     völligem    Ausschluss  von     Feuchtigkeit    zu     einem        hochchlorierten     Produkt kommt.

   das sich von einem     Antlira-          chinon    ableitet, welches     ini    substituierten  Kern     tetrahydriert    ist und das, was das Wich  tigste ist, noch Stickstoff enthält. Weder diese  Darstellungsmethode, noch der erhaltene Kör  per selbst waren bis heute bekannt.  



       Das    Verfahren wird erläutert durch fol  gendes Beispiel.  



       Beispiel:     20     gr        feinpulveriges,        trockenes        i3-Amino-          antlirachinon    werden in<B>600</B> cm' Chlorbenzol  suspendiert und durch Einleiten von gasför  miger Salzsäure in das salzsaure Salz ver  wandelt. Dann wird gekühlt und Chlor ein  geleitet, wobei man gegen Ende der Reaktion  die Temperatur allmählich bis zum Siede  punkt des Chlorbenzols steigert. Die entstan  dene     Lösung    wird     irn        Vakuum    eingedampft    und der Rückstand mit     Tetrachlorkohlenstoff     versetzt. Das Reaktionsprodukt scheidet sich  als Kristallbrei ab.  



  Der erhaltene Körper, das     Pentachlor-r?-          chlorketiminotetrahy        droarithrachinori    der     For-          rnel     
EMI0001.0035     
    bildet rhombische Blättchen vom Schmelzpunkt  210 o. Analyse: Chlor berechnet 49,23      ,!o,    ge  funden 49,02 0%.     E    r soll als neues Zwischen  produkt für die     Farbstoffindustrie    Verwen  dung     finden.  



  Process for the preparation of a highly chlorinated, nitrogen-containing, hydroaromatic product. It has been found that when the hydrochloric acid salt of P-arriiro-anthraquinone is chlorinated in an extremely different suspension medium which does not allow hydrolysis to take place, a highly chlorinated product is obtained with the complete exclusion of moisture.

   which is derived from an anti-lirquinone, which is tetrahydrated in a substituted nucleus and what is most important still contains nitrogen. Neither this method of representation nor the body itself was known to this day.



       The procedure is illustrated by the following example.



       Example: 20 grams of finely powdered, dry 13-amino-antlirachinone are suspended in <B> 600 </B> cm 'chlorobenzene and converted into the hydrochloric acid salt by introducing gaseous hydrochloric acid. The mixture is then cooled and chlorine is passed in, the temperature being gradually increased towards the end of the reaction to the boiling point of the chlorobenzene. The resulting solution is evaporated in vacuo and carbon tetrachloride is added to the residue. The reaction product separates out as a crystal slurry.



  The preserved body, the pentachlor-r? - chlorketiminotetrahy droarithrachinori the formula
EMI0001.0035
    forms rhombic flakes with a melting point of 210 °. Analysis: chlorine calculated 49.23,! o, found 49.02 0%. It is intended to be used as a new intermediate product for the dye industry.
