Patentiert im Deutschen Reiche vom 8. November 1906 ab.Patented in the German Empire on November 8, 1906.
Es hat sich gezeigt, daß die Dihalogenverbindungen des 3-Ketodihydro(i)thionaphtens sowie der Homologen und der Derivate dieser Verbindung (cf. französ. Patent 374287) leicht in 2 · 3-Diketodihydro(i)thionaphten oder Derivate desselben verwandelt werden können.It has been shown that the dihalogen compounds of 3-ketodihydro (i) thionaphthene and the homologues and derivatives thereof Compound (cf. French patent 374287) easily in 2 · 3-diketodihydro (i) thionaphtene or derivatives the same can be transformed.
Läßt man auf 2^Dihalogen-3-ketodihydro(i)-thionaphtene alkalische Mittel oder konzentrierte Schwefelsäure oder trockene saure Salze einwirken, so entstehen Thioindigofarbstoffe. Behandelt man dagegen die 2-Dihalogen-3-ketodihydro(i)thionaphtene mit Wasser, oder sauren verseifenden Mitteln, so werden dieselben unter Ersatz der beiden Halogenatome durch Sauerstoff in 2 · 3-Diketodihydro (1)thionaphten bzw. dessen Homologen oder Derivate übergeführt. Sofern hierbei gleichzeitig geringe Mengen von Farbstoff entstehen, kann man letzteren leicht abtrennen, z. B. durch Auflösen des 2 · 3-Diketodihydro (1) thionaphtens in verdünnter Essigsäure und Abfiltrieren. Wenn man auf die genannten Dihalogenketodihydrothionaphtene Körper, welche primäre Aminogruppen enthalten, wie Amine, Hydrazine oder Hydroxylamin usw., einwirken läßt, so entstehen unter Abspaltung von Halogenwasserstoffsäure Derivate von 2 · 3-Diketodihydrothionaphtenen. Dieselben lassen sich durch Behandlung mit verseifenden Mitteln in 2 · 3-Diketodihydrothionaphtene überführen.If one leaves on 2 ^ dihalo-3-ketodihydro (i) -thionaphtene When alkaline agents or concentrated sulfuric acid or dry acidic salts act, thioindigo dyes are formed. If, on the other hand, the 2-dihalo-3-ketodihydro (i) thionaphtenes are treated with water, or with acidic saponifying agents, they are replaced by the two halogen atoms by oxygen in 2 · 3-diketodihydro (1) thionaphtene or its homologues or derivatives converted. Provided that at the same time low Amounts of dye arise, you can easily separate the latter, z. B. by Dissolve the 2x3-diketodihydro (1) thionaphthene in dilute acetic acid and filter off. If you look at the mentioned Dihalogenketodihydrothionaphtene body, which primary Contain amino groups, such as amines, hydrazines or hydroxylamine etc., can act, in this way derivatives of 2 · 3-diketodihydrothionaphthens are formed with the elimination of hydrohalic acid. These can be converted into 2 · 3-diketodihydrothionaphthens by treatment with saponifying agents.
2-Dichlor-3 -ketodihydro (1) thionaphten wird mit Wasser einige Zeit gekocht. Die erhaltene 40 2-dichloro-3-ketodihydro (1) thionaphten is boiled with water for some time. The 40

goldgelbe Lösung wird filtriert und abgekühlt, wobei sich das entstandene 2 · 3-Diketodihydro (1) thionaphten abscheidet. Es bildet orangegelbe Prismen vom Schmelzpunkt ii8°. golden yellow solution is filtered and cooled, the resulting 2 · 3-diketodihydro (1) separates thionaphtene. It forms orange-yellow prisms with a melting point of ii8 °.
2-Dibrom-3-ketodihydro (1) thionaphten wird mit 3oprozentiger Essigsäure bis zum Entstehen einer Lösung gekocht; beim Abkühlen der eventuell filtrierten Lösung scheidet sich das 2 · 3-Diketodihydro (1) thionaphten ab.2-Dibromo-3-ketodihydro (1) thionaphten is treated with 3% acetic acid until it forms boiled a solution; when the possibly filtered solution cools, it separates the 2x3-diketodihydro (1) thionaphtene.
Es ist nicht erforderlich, von isolierter Dihalogenverbindung auszugehen, vielmehr kann man z. B. die bei der Darstellung der Dihalogenderivate erhaltenen Reaktionsmassen (vgl. z. B. Beispiel 3 der französ. Patentschrift 374287) direkt weiter auf 2·3-Diketodihydro(1)-thionaphten verarbeiten, indem man mit heißem Wasser verdünnt und kocht.It is not required of isolated dihalogen compound go out, rather you can z. B. those in the representation of the dihalogen derivatives reaction masses obtained (cf., for example, Example 3 of French Patent 374287) directly further to 2 · 3-diketodihydro (1) -thionaphthene process by diluting with hot water and boiling.
Wird in obigen Beispielen an Stelle der dort genannten 2-Dihalogen-3-ketodihydrothiqnaphtene s-Methyl^-dibrom-s-ketodihydrothionäphten oder 5 - Chlor - 2 - dibrom - 3 - ketodihydrothionaphten usw. verwendet, so erhält man 5-Methyl- bzw. 5-Chlor-2 · 3-diketodihydro(i)-thionaphten von ganz ähnlichen Eigenschaften wie das 2 · 3-Diketodihydrothionaphten,Is used in the above examples instead of the 2-dihalo-3-ketodihydrothiqnaphtene mentioned there s-methyl ^ -dibromo-s-ketodihydrothionäphten or 5 - chloro - 2 - dibromo - 3 - ketodihydrothionaphthene etc. are used, one obtains 5-methyl- or 5-chloro-2 · 3-diketodihydro (i) -thionaphthene of very similar properties to the 2 3-diketodihydrothionaphthene,
Das 5-Methyl-2 · 3-diketodihydro(i) thionaphten ist in ganz reinem Zustand, mit Wasserdampf destilliert, orangegelb; aus Alkohol umkristallisiert bildet es braune · Tafeln vom Schmelzpunkt 143 bis 144 °; Chloroform und Eisessig lösen es sehr leicht, Petroläther fast nicht.The 5-methyl-2 · 3-diketodihydro (i) thionaphten is in a completely pure state, with water vapor distilled, orange-yellow; Recrystallized from alcohol, it forms brown tablets from Melting point 143 to 144 °; Chloroform and Glacial acetic acid dissolves it very easily, petroleum ether almost not.

Beispiel III.Example III.
Zu einer heißen Lösung von 30,8 Teilen 2-Dibrom-3-ketodihydrothionaphten in AlkoholTo a hot solution of 30.8 parts of 2-dibromo-3-ketodihydrothionaphthene in alcohol
ίο fügt man eine heiße alkoholische Lösung von 30 Teilen kristallisiertem Natriumacetat und 9,3 Teilen Anilin hinzu und erwärmt etwa 1/2 Stunde auf dem Wasserbad. Hierauf wird die Flüssigkeit in das zehnfache Volum kalten , 15 angesäuerten Wassers eingegossen, das in braunen Flocken abgeschiedene Reaktionsprodukt abgesaugt, mit Wasser gewaschen und getrocknet. Es ist in organischen Mitteln leicht mit gelbbrauner Farbe löslich; aus der Lösung in Äther läßt es sich durch Ligroin in hellbraunen, mikrokristallinischen Flocken ausfällen.ίο one adds a hot alcoholic solution of 30 parts of crystallized sodium acetate and 9.3 parts of aniline and warms about 1/2 hour on the water bath. The liquid is then poured into ten times its volume of cold , acidified water, and the reaction product, which has separated out in brown flakes, is suctioned off, washed with water and dried. It is easily soluble in organic means with a yellow-brown color; from the solution in ether it can be precipitated by ligroin in light brown, microcrystalline flakes.
Man kann auch so verfahren, daß man die alkoholische Lösung einige Zeit bei gewöhnlicher Temperatur unter öfterem Umschütteln stellen läßt," wobei die Reaktionsmasse zu einem Brei brauner Flocken erstarrt. Mit verdünnter Essigsäure unter Zusatz einiger Tropfen Mineralsäure- gekocht, zerfällt die Verbindung in Anilin und 2 · 3-Diketodihydrothionaphten. Erwärmt man die.trockene Substanz einige Zeit auf dem Wasserbad, so gelingt die Verseifung nicht mehr glatt.One can also proceed in such a way that one uses the alcoholic solution for some time with ordinary Temperature can be set with frequent shaking, "whereby the reaction mass solidifies to a paste of brown flakes. With When boiled with dilute acetic acid with the addition of a few drops of mineral acid, the compound breaks down in aniline and 2x3-diketodihydrothionaphthene. The dry substance is heated for a while on the water bath, the saponification no longer works smoothly.
