Description

  

  Verfahren zur Darstellung eines     Farbstoffes    der     Diogazinreihe.       Gegenstand des vorliegenden Zusatzpa  tentes ist ein Verfahren zur Darstellung  eines Farbstoffes der     Dioxazinreihe,    welches  dadurch gekennzeichnet ist, dass man 1     Mol          Chloranil    mit 2     Mol        3-Aminophenanthren     in     Gegenwart    eines hochsiedenden Lösungs  mittels langsam bis zum Sieden erhitzt und  die so erhältliche     Verbindung        sulfiert.     



  Die so erhältliche     Dioxazinsulfosäure    löst  sich mit Wasser in violetter Farbe und färbt  die tierische, pflanzliche und künstliche Faser  in blaustichig violetten Tönen von hervor  ragenden Echtheitseigenschaften.    <I>Beispiel</I>  19,3 Gewichtsteile     3-Aminophenanthren     und 14 Gewichtsteilen     Chloranil    werden .in  300 -Gewichtsteile Nitrobenzol langsam bis  zum Sieden erhitzt. Man lässt 1 Stunde kochen  und saugt das ausgeschiedene Reaktions  produkt bei 120     0_    C ab und wäscht mit     Nitro-          benzol    und Alkohol. Das in grün glänzenden    Nadeln kristallisierte Produkt zeigt als Pig  ment blauviolette Farbe. Die Lösungsfarbe  in Monohydrat ist violett.  



  10 Teile dieses Pigments werden in 200  Gewichtsteilen 10     o/oigem        Oleum    bei zirka  200 C 1     Stunde    verrührt. Man gibt auf Eis,  saugt die ausgeschiedene     Sulfosäure    ab und  wäscht mit Kochsalzlösung neutral. Die     Sulfo-          säure    löst sich in Wasser mit violetter Farbe  und färbt die tierische, pflanzliche und  künstliche Faser in blaustichig violetten  Tönen an. Die Färbungen besitzen hervor  ragende Echtheitseigenschaften.



  Process for the preparation of a dye of the Diogazine series. The subject of the present Zusatzpa tentes is a process for the preparation of a dye of the dioxazine series, which is characterized in that 1 mole of chloranil is slowly heated to boiling with 2 moles of 3-aminophenanthrene in the presence of a high-boiling solution and the compound thus obtained is sulfated.



  The dioxazine sulfonic acid obtainable in this way dissolves in water in a violet color and colors the animal, vegetable and artificial fibers in bluish violet tones with excellent fastness properties. <I> Example </I> 19.3 parts by weight of 3-aminophenanthrene and 14 parts by weight of chloranil are slowly heated to boiling in 300 parts by weight of nitrobenzene. The mixture is left to boil for 1 hour and the reaction product which has separated out is filtered off with suction at 120 ° C. and washed with nitrobenzene and alcohol. The product, crystallized in shiny green needles, has a blue-violet color as a pigment. The solution color in monohydrate is purple.



  10 parts of this pigment are stirred in 200 parts by weight of 10% strength oleum at about 200 ° C. for 1 hour. It is poured onto ice, the sulfonic acid which has separated out is filtered off with suction and washed neutral with sodium chloride solution. The sulphonic acid dissolves in water with a violet color and stains the animal, vegetable and artificial fibers in blue-tinged violet tones. The dyeings have excellent fastness properties.
