Description

  

  <B>Zusatzpatent</B> zum Hauptpatent Nr. 124526.    Verfahren zur Herstellung eines neuen     Anthr        achinonderivates.       Es wurde gefunden, dass man ein neues       Anthrachinonderivat    erhält, wenn man     Me-          thylolbenzamid    mit     -2-Oxyanthrachinon    kon  densiert.  



  Die so erhaltene     Verbindung    stellt sehr  wahrscheinlich das     1-Benzoylaminomethyl-2-          oxyanthrachinon    dar und bildet schöne, gelbe  Nadeln, welche bei 250   unter Zersetzung  schmelzen. In konzentrierter Schwefelsäure  löst es sich rotbraun, in     kaustischen    Alkalien  braun. Das neue Produkt wird zur Herstellung  von     Farbstoffen    und weitern Zwischenpro  dukten verwendet.    <I>Beispiel:</I>  In eine kalt bereitete Lösung von 2 Teilen       2-oxyanthrachinon    in 30 Teilen konzentrierter  Schwefelsäure trägt man allmählich unter  Wasserkühlung 1,4 Teile     Methylolbenzamid     ein und lässt dann längere Zeit stehen.

   Hier  auf wird auf Eis ausgetragen, der gebildete  Niederschlag filtriert, neutral gewaschen und  zur Entfernung von unveränderten 2-Oxy-         anthrachinon    mit warmem Wasser behandelt.  Das nunmehr vom Ausgangsmaterial befreite  und getrocknete Reaktionsprodukt wird als  dann mit Benzol ausgezogen, der Benzol  extrakt verdampft und der Rückstand aus  Eisessig umkristallisiert.



  <B> Additional patent </B> to main patent No. 124526. Process for the production of a new anthracinone derivative. It has been found that a new anthraquinone derivative is obtained if methylolbenzamide is condensed with -2-oxyanthraquinone.



  The compound thus obtained is very likely to be 1-benzoylaminomethyl-2-oxyanthraquinone and forms beautiful, yellow needles which melt at 250 ° C with decomposition. It dissolves red-brown in concentrated sulfuric acid and brown in caustic alkalis. The new product is used to manufacture dyes and other intermediate products. <I> Example: </I> 1.4 parts of methylolbenzamide are gradually added to a cold solution of 2 parts of 2-oxyanthraquinone in 30 parts of concentrated sulfuric acid with water cooling and then left to stand for a long time.

   Here, it is poured onto ice, the precipitate formed is filtered, washed neutral and treated with warm water to remove unchanged 2-oxyanthraquinone. The reaction product, which has now been freed from the starting material and dried, is then extracted with benzene, the benzene extract is evaporated and the residue is recrystallized from glacial acetic acid.
