Description
Verfahren zur Darstellung eines Derivates des Anthanthrons. Es wurde gefunden, dass man bisher un bekannte, technisch wertvolle Oxy- bezw. Alkoxyderivate des Anthanthrons erhält, wenn man Sulfosäuren bezw. Alkoxyderivate des Naphthostyrils durch Einwirkung von alkalischen Verseifungsmitteln in die ent sprechenden Derivate der 1-Aminonaphtha- lin-8-carbonsäure überführt,
deren Diazover- bindungen mit reduzierenden Mitteln behan delt, die so gebildeten Derivate der<B>1.</B> l'- Dinaphthyl-8.8'-dicarbonsäure, soweit sie Sulfogruppen enthalten, durch Alkali schmelze in die entsprechenden Oxyderivate überführt und endlich die erhaltenen Oxy- bezw. Alkoxyderivate der 1. 1'-Dinaphthyl 8 .
8'-dicarbonsäure der Einwirkung von sau ren Kondensationsmitteln, insbesondere von Schwefelsäure oder Chlorzink, unterwirft.
Die Oxyauthanthrone können durch nach trägliche Alkylierung in die Alkoxyanthan- throne übergeführt werden, so dass man auch auf diese Weise zu letzteren gelangen kann.
Vorliegendes Patent bezieht sich nun auf die Darstellung eines Dioxyanthanthrons, da durch gekennzeichnet, dass man die durch Sul- fieren von Naphthostyril mit Schwefelsäure erhältliche Sulfosäure zur 1-Amino-4-sulfo- naphthalin-8-carbonsäure verseift, deren Di- azoverbindung mit einem Reduktionsmittel behandelt, die erhaltene 1.1'-Dinaphthyl- 4.4'-disulfo-8.8'-dicarbonsäure durch Al- ka-Iischmelze in die 1 .
1'-Dinaphthyl-4.4'- dioxy-8.8'-dicarbonsäure überführt und diese endlich der Einwirkung von sauren Kondensationsmitteln unterwirft.
Getrocknet ist das neue Dioxyanthan- thron ein bräunlichrotes Pulver, löslich in konzentrierter Schwefelsäure mit gelbgrüner Farbe. In heisser Alkalilauge löst es sich schwer mit grünblauer Farbe. Die Hydro- sulfitküpe ist blaurot. Es soll als Zwischen produkt zur Herstellung von Farbstoffen Verwendung finden.
<I>Beispiel:</I> <I>a) Darstellung der 1</I> .1'-Dinaphthyl-4 <I>.</I> 4'- disulf <I>o-8 .</I> 8'-diearbonsäure 1.69 Teile Naphthostyril werden mit 1000 Teilen konzentrierter Schwefelsäure so lange auf 90 erwärmt, bis eine Probe in Wasser löslich ist. Nach Erkalten wird das Sulfierungsgemisch auf Eis gegossen, mit Kaliumchlorid ausgesalzen, abgesaugt und mit Kaliumchloridlösung gewaschen.
Durch Kochen mit 10 %iger Natronlauge wird die Naphthostyrilsulfosäure in die 1-Amino-4- sulfonaphthalin-8-carbonsäure übergeführt. Zur Umwandlung in die Dinaphthyl-disulfo- dicarbonsäure wird die so erhaltene Amino- sulfo-naphthalin-carbonsäure in üblicher Weise diazotiert und die schwer lös liche Diazoverbindung in eine aus 500 Teilen Kupfervitriol hergestellte ammonia- kalische
Kupferoxydullösung eingetragen. Durch Ansäuern und Aussalzen mit Koch salz wird die 1 . 1'-Dinaphthyl-4.4'-disulfo- 8.8'-dicarbonsäure zur Abscheidung ge bracht.

Die Temperatur der Schmelze wird allmählich gesteigert und kurze Zeit bei 180 bis<B>190'</B> gehalten.
Nach Erkalten wird die Schmelze mit Wasser auf genommen, durch vorsichtiges Ansäuern mit Salzsäure die gebildete 4.4'-Dioxy-1 . 1'-di- naphthy 1-8 . 8'-dicarbonsäure zur Abschei- dung gebracht, filtriert und mit wenig Eis wasser gewaschen. Durch Umkristallisieren aus Wasser wird sie in farblosen Kristallen erhalten.

Process for the preparation of a derivative of the anthanthrone. It has been found that previously unknown, technically valuable Oxy- bezw. Alkoxy derivatives of anthanthrone obtained when sulfonic acids bezw. Alkoxy derivatives of naphthostyril converted into the corresponding derivatives of 1-aminonaphthaline-8-carboxylic acid by the action of alkaline saponifying agents,
whose diazo compounds are treated with reducing agents, the derivatives of 1. l'-dinaphthyl-8.8'-dicarboxylic acid formed in this way, insofar as they contain sulfo groups, are converted into the corresponding oxy derivatives by alkali melt and finally the obtained Oxy- respectively. Alkoxy derivatives of 1. 1'-Dinaphthyl 8.
8'-dicarboxylic acid subjected to the action of acidic condensing agents, in particular sulfuric acid or zinc chloride.
The oxyauthanthrones can be converted into the alkoxyanthan thrones by subsequent alkylation, so that the latter can also be obtained in this way.
The present patent now relates to the preparation of a dioxyanthanthrone, characterized in that the sulfonic acid obtainable by sulphuring naphthostyril with sulfuric acid is saponified to give 1-amino-4-sulfonaphthalene-8-carboxylic acid, the diazo compound thereof with a Treated reducing agent, the 1.1'-dinaphthyl-4.4'-disulfo-8.8'-dicarboxylic acid obtained by alkali melt in the 1.
1'-Dinaphthyl-4.4'-dioxy-8.8'-dicarboxylic acid transferred and finally subjected to the action of acidic condensing agents.
When dried, the new dioxyanthan thron is a brownish-red powder, soluble in concentrated sulfuric acid with a yellow-green color. In hot alkali it is difficult to dissolve with a green-blue color. The hydrosulfite vat is bluish red. It should be used as an intermediate product for the production of dyes.
<I> Example: </I> <I> a) Representation of the 1 </I> .1'-Dinaphthyl-4 <I>. </I> 4'-disulf <I> o-8. </ I > 8'-diacid 1.69 parts of naphthostyril are heated to 90 with 1000 parts of concentrated sulfuric acid until a sample is soluble in water. After cooling, the sulfonation mixture is poured onto ice, salted out with potassium chloride, filtered off with suction and washed with potassium chloride solution.
The naphthostyril sulfonic acid is converted into 1-amino-4-sulfonaphthalene-8-carboxylic acid by boiling with 10% sodium hydroxide solution. To convert it into the dinaphthyl-disulfodicarboxylic acid, the aminosulfonaphthalene-carboxylic acid obtained in this way is diazotized in the customary manner and the poorly soluble diazo compound is converted into an ammoniacal one made from 500 parts of vitriol
Entered copper oxide solution. By acidifying and salting out with cooking salt, the 1st 1'-Dinaphthyl-4.4'-disulfo-8.8'-dicarboxylic acid brought to the deposition.

The temperature of the melt is gradually increased and kept at 180 to <B> 190 '</B> for a short time.
After cooling, the melt is taken up with water, the 4,4'-dioxy-1 formed by careful acidification with hydrochloric acid. 1'-di-naphthy 1-8. 8'-dicarboxylic acid deposited, filtered and washed with a little ice water. It is obtained in colorless crystals by recrystallization from water.
