Description

  

  <B>Zusatzpatent</B> zum Hauptpatent Nr.     12.4526.       Verfahren zur Herstellung eines neuen     Anthrachinonderivates.       Es wurde gefunden, dass man ein neues       Anthrachinonderivat    erhält, wenn man     Dime-          thylolharnstoff    mit     2-Oxyanthrachinon    kon  densiert.  



  Die so erhaltene Verbindung stellt sehr  wahrscheinlich den     sym-(2,2'-Dioxydianthra-          chinonyl)-dimethylharnstoff    dar und bildet       grünlichgelbe    Kristalle, welche bei 250    unter Zersetzung schmelzen. In konzentrierter  Schwefelsäure löst er sich rot, in     kaustischen          Alkalien    ebenfalls rot. Das neue Produkt  wird zur Herstellung von     Farbstoffen    und  weiteren Zwischenprodukten verwendet.  



       Beispiel:     Einer Lösung von 5 Teilen     2-Oxyanthra-          chinon    in 50 Teilen konzentrierter Schwefel  säure gibt man allmählich unter Rühren  3 Teile     Dimethylolharnstoff    zu und lässt  2 Tage rühren. Der durch Giessen dieser    Lösung auf Eis erhaltene Niederschlag wird  mit Alkohol ausgekocht und der verbleibende  Rückstand aus     Pyridin    umkristallisiert.



  <B> Additional patent </B> to main patent No. 12.4526. Process for the production of a new anthraquinone derivative. It has been found that a new anthraquinone derivative is obtained if dimethylolurea is condensed with 2-oxyanthraquinone.



  The compound obtained in this way very probably represents sym- (2,2'-dioxydianthraquinonyl) -dimethylurea and forms greenish-yellow crystals which melt at 250 ° C with decomposition. It dissolves red in concentrated sulfuric acid, and red in caustic alkalis. The new product is used to manufacture dyes and other intermediate products.



       Example: A solution of 5 parts of 2-oxyanthraquinone in 50 parts of concentrated sulfuric acid is gradually added to 3 parts of dimethylolurea with stirring and allowed to stir for 2 days. The precipitate obtained by pouring this solution onto ice is boiled with alcohol and the remaining residue is recrystallized from pyridine.

PATENTANSPRUCH: Verfahren zur Herstellung eines neuen Anthrachinonderivates dadurch gekennzeich net, dass man Dimethylolharnstoff mit 2-Oxy- anthrachition kondensiert. Die so erhaltene Verbindung stellt sehr wahrscheinlich den sym-(2,2'-Dioxydianthra- chinonyl)-dimethylharnstoff dar und bildet grünlichgelbe Kristalle, welche bei 2500 unter Zersetzung schmelzen. In konzentrierter Schwefelsäure löst er sich rot, in kaustischen Alkalien ebenfalls rot. PATENT CLAIM: Process for the production of a new anthraquinone derivative characterized in that dimethylolurea is condensed with 2-oxyanthraite ion. The compound obtained in this way very probably represents the sym- (2,2'-dioxydianthraquinonyl) -dimethylurea and forms greenish-yellow crystals which melt at 2500 with decomposition. It dissolves red in concentrated sulfuric acid, and red in caustic alkalis. Das neue Produkt wird zur Herstellung von Farbstoffen und weiteren Zwischenprodukten verwendet. The new product is used to manufacture dyes and other intermediate products.
