(erhältlich durch Kondensation von Chloranil und 3-Amino-N-äthylcarbazol-6-carbonsäure- äthylester) in die Dioxazinverbindung über führt und den so gebildeten Dioxazincarbon- säureester mit einem verseifenden Mittel be handelt.
Die Überführung in die Dioxazinverbin- dung kann durch Erhitzen der obengenannten Verbindung in einem organischen Lösungs mittel, z. B. in Trichlorbenzol oder in Ni- trobenzol, zweckmässig in Gegenwart eines acylierenden Mittels, wie Benzoylchlorid, Benzolsulfochlorid, p-Nitrobenzolsulfochlorid, pToluolsulfochlorid, erfolgen. Der so gebil dete Dioxazincarbonsäureester wird mit ver- seifenden Mitteln, z.
B. mit Schwefelsäure oder Oleum, behandelt.
Die Herstellung des Kondensationspro duktes aus Chloranil und 3-A.mino-N-äthyl- carbazol - 6 - carbonsäureätliylester und die Überführung dieser Verbindung in das Di- oxazin kann auch in einem Arbeitsgang ohne Isolierung der Benzochinon-Verbindung er folgen.
Man kann die Überführung des Diäthyl- esters des 2.5-Di-(6'-cai-boxy-N-äthylcarb- azolyl-3'-amirio)-3 . 6-dichlorlienzochinons in die Dioxazinverbindung auch in starker Schwefelsäure oder in Oleum vornehmen. Da bei erfolgt gleichzeitig die Verseifung der Carbonsäureestergruppen.
Der neue Farbstoff hat die folgende For mel:

<I>Beispiele:</I> 1. 13 Gewichtsteile Chloranil, 28,2 Ge wichtsteile 3-Amino-N-äthylcarl)azol-6-car- bonsäure-äthylesier und 9 Gewichtsteile Na triumacetat werden in 300 Gewichtsteilen Trichlorbenzol einige Zeit, auf 120' C er hitzt. Darauf heizt man allmählich zum Sie den und destilliert die gebildete Essigsäure ab. Nach Zugabe von 20 Gewichtsteilen m- Nitrobenzolsulfochlorid wird noch eine Stunde gekocht. Man saugt bei etwa 50 C ab, und wäscht mit Trichlorbenzol und Alkohol nach.
Der Dioxazincarbonsäureester wird in Form von Nadeln mit grünem Oberflächenglanz er halten.
10 Gewichtsteile dieser Verbindung wer den in 200 Gewichtsteilen 10%igem Oleum 10 Minuten bei Zimmertemperatur verrührt. Man gibt auf Eis, saugt ab und wäscht mit Wasser neutral. Der in verdünnter Soda lösung in Form des Natriumsalzes gut lös liche Farbstoff färbt die pflanzliche, künst liche und tierische Faser in klaren blauen Tönen von sehr guten Echtheitseigenschaften.

Nach dem Erkalten gibt man auf Eis, saugt ab und wäscht mit Kochsalzlösung neutral. Der so erhaltene Farbstoff hat die in dem obigen Beispiel angegebenen Eigen schaften.
Process for the preparation of a dye of the dioxazine series. The subject of this additional patent is a process for the production of a dye of the dioxazine series, which consists in that the diethyl ester of 2.5-di- (6'-carboxy- N - ethylcarbazolyl - <B> 3'- </B> amino) - ' 3.
6 - dichlorobenzoehinons of the formula
EMI0001.0011
(obtainable by condensation of chloranil and 3-amino-N-ethylcarbazole-6-carboxylic acid ethyl ester) converts into the dioxazine compound and treats the dioxazine carboxylic acid ester thus formed with a saponifying agent.
The conversion into the dioxazine compound can medium by heating the abovementioned compound in an organic solvent, eg. B. in trichlorobenzene or in nitrobenzene, conveniently in the presence of an acylating agent such as benzoyl chloride, benzenesulfonyl chloride, p-nitrobenzenesulfonyl chloride, p-toluenesulfonyl chloride. The so gebil ended Dioxazincarbonsäureester with saponifying agents such.
B. with sulfuric acid or oleum treated.
The production of the condensation product from chloranil and 3-amino-N-ethyl-carbazole-6-carboxylic acid ethyl ester and the conversion of this compound into the oxazine can also be carried out in one operation without isolating the benzoquinone compound.
One can convert the diethyl ester of 2.5-di- (6'-cai-boxy-N-ethylcarbazolyl-3'-amirio) -3. Make 6-dichlorlienoquinones in the dioxazine compound also in strong sulfuric acid or in oleum. Since the saponification of the carboxylic acid ester groups takes place at the same time.
The new dye has the following formula:
EMI0002.0011
<I> Examples: </I> 1. 13 parts by weight of chloranil, 28.2 parts by weight of 3-amino-N-ethylcarl) azole-6-carboxylic acid ethylsier and 9 parts by weight of sodium acetate are mixed in 300 parts by weight of trichlorobenzene for some time it heats up to 120 ° C. It is then gradually heated to you and the acetic acid formed is distilled off. After adding 20 parts by weight of m-nitrobenzenesulfonyl chloride, the mixture is boiled for a further hour. It is suctioned off at about 50 C and washed with trichlorobenzene and alcohol.
The dioxazine carboxylic acid ester is kept in the form of needles with a green surface luster.
10 parts by weight of this compound are stirred in 200 parts by weight of 10% strength oleum for 10 minutes at room temperature. It is poured onto ice, filtered off with suction and washed neutral with water. The dye, which is readily soluble in the form of the sodium salt in a dilute soda solution, dyes the vegetable, artificial and animal fibers in clear blue shades with very good fastness properties.
2. 10 parts by weight of the diethyl ester of the 2nd 5 - di - (6 '- carboxy-N-ethylcarbazolyl-3'-amino) -3,6-dichlorobenzoquinones (obtainable by condensation of chloranil with 3 amino-N-ethyl-carbazole-6-carboxylic acid ethyl ester in alcohol) are in 200 Share by weight 1% oleum, stirred at 150 ° C. for some time. After cooling, it is poured onto ice, filtered off with suction and washed neutral with saline. The dye thus obtained has the properties given in the above example.
