Description
Verfahren zur Darstellung einer Diogazinfarbstoffsulfosäure. Gegenstand des vorliegenden Patentes ist ein Verfahren zur Darstellung einer Dioxazin- farbstoffsulfosäure, welches dadurch gekenn zeichnet ist, dass man 2,5-Di-(N-äthylcarba- zolyl-3'-amino-6'-sulfosäure)-3 . 6-dicblor-1. 4- benzochinon mitKaliumpermanganat in Gegen wart von Natronlauge behandelt.
<I>Beispiel:</I> 87Gewichtsteile 2,5-Di-(N-äthylcarbazolyl- 3'-amino-6'-sulfosäure)-3. 6-dichlor-1. 4-benzo- chinon, erhältlich aus Chloranil und 3-Amino- (N)-äthylcar-bazol-6-sulfosäure durch Umsetzen in Alkohol oder wässrigem Alkohol in Gegen wart von säurebindenden Mitteln, werden in einem Liter Wasser gelöst.
Zu der mit<B>10</B> cm' konzentrierter Natronlauge versetzten braunen Lösung gibt man 63 g Kaliumpermanganat in fester Form oder in Lösung und verrührt einige Zeit, bis eine in Wasser aufgenommene Probe rein blau erscheint. DieReaktionsmasse wird darauf durch Abfilteieren vom Mangan- dioxyd befreit und letzteres nochmals mit heissem Wasser ausgezogen. Die mit Koch salz ausgefällte Sulfosäure wird abfiltriert, gewaschen und getrocknet. Sie färbt die tierische, pflanzliche und Viscose-Faser sowie gemischte Gewebe in echten klaren Blau tönen.
Process for the preparation of a diogazine dye sulfonic acid. The present patent relates to a process for the preparation of a dioxazine dye sulfonic acid, which is characterized in that 2,5-di- (N-ethylcarba- zolyl-3'-amino-6'-sulfonic acid) -3. 6-dicblor-1. 4-benzoquinone treated with potassium permanganate in the presence of sodium hydroxide solution.
<I> Example: </I> 87 parts by weight of 2,5-di- (N-ethylcarbazolyl-3'-amino-6'-sulfonic acid) -3. 6-dichloro-1. 4-benzoquinone, obtainable from chloranil and 3-amino- (N) -äthylcar-bazol-6-sulfonic acid by reaction in alcohol or aqueous alcohol in the presence of acid-binding agents, are dissolved in one liter of water.
63 g of potassium permanganate in solid form or in solution are added to the brown solution to which 10 cm 'concentrated sodium hydroxide solution has been added and the mixture is stirred for a while until a sample taken up in water appears pure blue. The reaction mass is then freed from the manganese dioxide by filtering it off and the latter is extracted again with hot water. The sulfonic acid precipitated with sodium chloride is filtered off, washed and dried. It colors the animal, vegetable and viscose fibers as well as mixed fabrics in real clear blue tones.
