Description
Verfahren zur Herstellung eines indigolden Farbstoffes der Anthracenreihe. Es wurde gefunden, dass man-einen neuen indigoiden Farbstoff der Anthra-eenreihe er hält, wenn man das 2,3-Anthrachinonoxythi- onap@hthen mit a-Is@atinanilid kondensiert.
Der neue Farbstoff ist in Schwefelsäure mit grüner Farbe löslich, mit Wasser wird: er in Form blauer Flocken ausgefällt. Er bildet mit Hydrosulfit und Natronlauge eine olive braune Küpe, aus welcher Baumwolle in vol len, echten, blauen Tönen gefärbt wird.
Beispiel: 28 Teile 2,3 - Anthrachinonoxythionaph- tUen und 25 Teile a-Isatinaniliel werden in 200 Teile Pyridin eingetragen und zum Sie den erhitzt. Es tritt sofort Reaktion ein unter Bildung eines blauen Farbstoffes, der erbfil- triert, gewaschen und getrocknet wird.
Process for the production of an indigolden dye of the anthracene series. It has been found that a new indigoid dye of the Anthra-een range is obtained if the 2,3-anthraquinone oxythionophthene is condensed with α-is @ atinanilide.
The new dye is soluble in sulfuric acid with a green color; with water it becomes: it is precipitated in the form of blue flakes. With hydrosulphite and caustic soda it forms an olive-brown vat from which cotton is dyed in full, genuine, blue tones.
Example: 28 parts of 2,3 - anthraquinone oxythionaphthene and 25 parts of a-isatin aniliel are added to 200 parts of pyridine and heated to you. A reaction occurs immediately with the formation of a blue dye, which is filtered off, washed and dried.
