Description

  

  <B>Zusatzpatent</B> zum     Hauptpatent    Nr.<B>116155.</B>    Verfahren zur Darstellung eines     Küpenfarbstoffes    der     Anthraehinonreihe.       Es wurde gefunden, dass man zu einem  neuen wertvollen     güpenfarbstoff    der     Anthra-          chinonreihe    dadurch gelangt, dass     manI-Amino-          4-benzoylaminoanthr-achinon    in organischen  Lösungsmitteln mit     Oxalylchlorid    in der  Wärme behandelt.  



  <I>Beispiel:</I>  68,4 Gewichtsteile     1-Amino-4-benzoylaini-          noanthrachinon    werden mit 1000 Gewichts  teilen Nitrobenzol auf<B>70"</B> erhitzt und lang  sam 12,7 Gewichtsteile     Oxalylchlorid    einge  rührt. Unter kräftigem Rühren wird dann die  Temperatur auf 110-115   gesteigert, bis kein       1-Amino-4-benzoylaminoanthrachinon    mehr  nachzuweisen ist. Das sehr schwer lösliche,  feinkristallisierte Reaktionsprodukt wird heiss  abgesaugt und mit Nitrobenzol und Alkohol  ausgewaschen. Der so erhältliche     Farbstoff       löst sich in konzentrierter Schwefelsäure rot.

    Er färbt aus stumpfblauer     Küpe    ein schönes       kräftiges    Orange von hervorragender Koch-,       Bäuch-    und Lichtechtheit.



  <B> Additional patent </B> to main patent no. <B> 116155. </B> Process for the preparation of a vat dye of the anthraehinone series. It has been found that a new valuable high quality dye of the anthrachinone series is obtained by treating I-amino-4-benzoylaminoanthr-aquinone in organic solvents with oxalyl chloride under heat.



  <I> Example: </I> 68.4 parts by weight of 1-amino-4-benzoylaininoanthraquinone are heated to <B> 70 "with 1000 parts by weight of nitrobenzene and 12.7 parts by weight of oxalyl chloride are slowly stirred in. The temperature is then increased to 110-115 while stirring vigorously until no more 1-amino-4-benzoylaminoanthraquinone can be detected. The finely crystallized reaction product, which is very difficult to dissolve, is suctioned off while hot and washed out with nitrobenzene and alcohol. The dye obtainable in this way dissolves in concentrated sulfuric acid red.

    From a dull blue vat it colors a beautiful, strong orange that is extremely fast to cook, tummy and light fast.

PATENTANSPRUCH: Verfahren zur Darstellung eines neuen wertvollen Küpenfarbstoffes der Anthrachinon- reihe, dadurch gekennzeichnet, dass man 1- Amirio-4-benzoylaminoanthrachinon in organi schen Lösungsmitteln mit Oxalylchlorid in der Wärme behandelt. Der so erhältliche Küpen- farbstoff löst sich in konzentrierter Schwefel säure rot und gibt aus stumpfblauer Küpe ein schönes kräftiges Orange von hervorragender Koch-, Bäuch- und Lichtechtheit. PATENT CLAIM: Process for the preparation of a new valuable vat dye of the anthraquinone series, characterized in that 1-amirio-4-benzoylaminoanthraquinone is treated in organic solvents with oxalyl chloride in the heat. The vat dye that can be obtained in this way dissolves in concentrated sulfuric acid in red and gives the dull blue vat a beautiful, strong orange that is extremely fast, tummy and lightfast.
