Description

  

  <B>Zusatzpatent</B> zum     Hauptpatent    Nr. 270836.    Verfahren zur Herstellung eines     Küpenfarbatoffes.       Es wurde gefunden, dass man zu einem  wertvollen     Küpenfarbstoff    gelangt, wenn man  ein     2-(2'-Naplithyl)-4-lialogen-6,7-plitbaloyl-          ehinazolin    der Formel  
EMI0001.0006     
    mit     4-Aininoanthrachinon-2,1-(N)-benzolacri-          don    umsetzt.  



  Der neue Farbstoff bildet ein dunkelgrü  nes Pulver, das Baumwolle aus v     iolettbrauner          Küpe    in starken, gelbgrünen Tönen von her  vorragender Echtheit färbt.  



  Als Ausgangsstoff verwendet man mit  Vorteil das     Chlorsubstitutionsprodukt    der  Formel  
EMI0001.0012     
    Die     Z?insetzung    kann zweckmässig in einem  hochsiedenden     Lösungs-    bzw. Verdünnungs-    mittel bei erhöhter Temperatur durchgeführt  werden. Als Lösungsmittel eignet sich     zum     Beispiel Phenol besonders gut.

           Beispiel,:     6 Teile     2-(2'-Naphthyl)-4-chlor-6,7-phtha-          loylchina.zolin    und 4,8 Teile     4-Aminoanthra-          ehinon-2,1-(N        )-benzolacridon    werden in 150  Teilen Phenol eine halbe Stunde zum Sieden  erhitzt, wobei Salzsäure entweicht. Man gibt.  150 Teile     Pyridin    zu, lässt auf etwa 500 ab  kühlen,     saugt    ab,     wäseht    den Rückstand mit       Alkohol    aus und trocknet ihn.  



  Das oben verwendete     2-(2'-Naphthyl)-4-          ehlor-6,7-phthaloylchinazolin    kann durch Er  hitzen des 2-     (2'-Naphthoyl)        -amino-3-eyan-          anthrachinons    der Formel  
EMI0001.0031     
    in Nitrobenzol mit     Phosphorpentachlorid    her  gestellt werden. Es stellt ein gelbbraunes Kri  stallpulver dar.



  <B> Additional patent </B> to main patent no. 270836. Process for the production of a vat colorant. It has been found that a valuable vat dye is obtained by using a 2- (2'-naplithyl) -4-lialogen-6,7-plitbaloyl-ehinazoline of the formula
EMI0001.0006
    with 4-aininoanthraquinone-2,1- (N) -benzolacridone implemented.



  The new dye forms a dark green powder that dyes cotton from a violet brown vat in strong, yellow-green shades with excellent fastness.



  The chlorine substitution product of the formula is advantageously used as the starting material
EMI0001.0012
    The decomposition can expediently be carried out in a high-boiling solvent or diluent at elevated temperature. Phenol, for example, is particularly suitable as a solvent.

           Example: 6 parts of 2- (2'-naphthyl) -4-chloro-6,7-phthalloylchina.zoline and 4.8 parts of 4-aminoanthra- ehinon-2,1- (N) -benzolacridone are used in 150 Parts of phenol heated to boiling for half an hour, hydrochloric acid escaping. One gives. 150 parts of pyridine are allowed to cool to about 500, filtered off with suction, the residue is washed out with alcohol and dried.



  The 2- (2'-naphthyl) -4-ehlor-6,7-phthaloylquinazoline used above can be obtained by heating the 2- (2'-naphthoyl) -amino-3-eyano-anthraquinone of the formula
EMI0001.0031
    be made in nitrobenzene with phosphorus pentachloride ago. It is a yellow-brown crystal powder.
