Description
Verfahren zur Herstellung eines Farbstoffes der Dioxazinreihe. Gegenstand dieses Patentes ist ein Ver fahren zur Herstellung eines Farbstoffes der Dioxazinreilie, welches darin besteht, dass man den Diäthylester des 2. 5-Di(4"-carboxy- diphenylamin <B>-</B> 4- amino) <B>- 3. 6 -</B> dichlor <B>- 1 .</B> 4- benzocIiinons von der Formel:

(erhältlich durch Kondensation von Chloranil mit 4-Aminodiphenylamin-4'-carbonsäure- äthylester) in die Dioxazinverbindung über führt und den so gebildeten Dioxazindiear- bonsäureester mit einem verseifenden Mittel behandelt.
Die Überfü'hrung in die Dioxazinverbin- dung erfolgt durch Erhitzen der oben ge nannten Verbindung in einem organischen Lösungsmittel, zum Beispiel in Nitrobenzol oder Trichlorbenzol, zwückmässig in Gegen wart eines acylierenden Mittels, wie z. B. p-Toluolsulf ochlorid, Benzoylchlorid, Benzol- sulfochlorid. Der so gebildete Dioxazindicar- bon,säureester wird mit verseifenden Mitteln, z.
B. mit Schweèlsäure, behandelt.
Der neue Farbstoff hat die folgende For- mel:

Process for the preparation of a dye of the dioxazine series. The subject of this patent is a process for the production of a dye of the dioxazine line, which consists in that the diethyl ester of 2. 5-di (4 "-carboxydiphenylamine <B> - </B> 4-amino) <B> - 3. 6 - </B> dichlor <B> - 1. </B> 4- benzocIiinons of the formula:
EMI0001.0013
(obtainable by condensation of chloranil with 4-aminodiphenylamine-4'-carboxylic acid ethyl ester) converts into the dioxazine compound and treats the dioxazine diacid ester thus formed with a saponifying agent.
The transfer into the dioxazine compound takes place by heating the abovementioned compound in an organic solvent, for example in nitrobenzene or trichlorobenzene, in the presence of an acylating agent, such as. B. p-toluenesulfochloride, benzoyl chloride, benzene sulfochloride. The dioxazine dicar- bon acid ester formed in this way is treated with saponifying agents, eg.
B. treated with sulfuric acid.
The new dye has the following formula:
EMI0002.0001
<I> Example: </I> <B> 10 </B> parts by weight of the diethyl ester of <B> 2. </B> 5-di- (4 "-ca.rboxy-diphenylamili-4'-amino) - 3. 6-diehlor-1 <B>. </B> 4-benzoquinones are heated to boiling in <B> 150 </B> parts by weight of nitrobenzene with the addition of 4 parts by weight of p-Toll-iolsulfochlorid until the color of the solution has turned blue .
After the reaction mass has been obtained, the compound formed in this way is filtered off: #, ab, - # Ääselit with alcohol and then with water and dried. The Dioxaziiidieit.rbonsäurediethylester, Qtellt is a greenish, black powder, which dissolves in concentrated sulfuric acid with an olive-green color.
<B> 10 </B> parts by weight of this compound in 20 parts by weight <B> 75 </B>% io sulfuric acid are heated to <B> 95 ° C </B> for one hour. After receiving - it is put on ice, suctioned off, ZD <I> In </I> washes with water and the residue is dissolved in a dilute soda solution. The sodium salt of the dicarboxylic acid is deposited by adding common salt to the solution. The dye is suctioned off and net getrock.
It dissolves in water with a blue color and dyes the vegetable, artificial and animal fibers in clear blue tones with excellent fastness properties.
