  Verfahren zur Herstellung eines neuen Zwischenproduktes der     Farbstoffindustrie.       Es wurde gefunden, dass man ein neues  Zwischenprodukt, das     p-Dimethylaminoanil     des     1,2-Anthracenthioisatins,    erhält, wenn  man das     1,2-Anthracenoxythiophen    mit     Ni-          trosodimethylanilin    kondensiert. Das     p-Di-          methylaminoanil    des     1,2-Anthracenthioisa-          tins    bildet ein braunviolettes Pulver, das in  niedrig siedenden     Lösungsmitteln    sehr schwer  löslich ist.

   Es löst sich in konzentrierter  Schwefelsäure mit     olivebrauner    Farbe. Die.  neue Verbindung wird zur Herstellung von  Farbstoffen verwendet.  



  <I>Beispiel:</I>  75 Teile     1,2-Anthracenogythiophen    wer  den in eine Mischung aus 1500 Teilen Al  kohol und     33    Teilen 30     %iger    Natronlauge  eingetragen, auf 40' erwärmt und hierauf  mit 48 Teilen     Nitrosodimethylanilin,    gelöst    in 300 Teilen Alkohol, versetzt. Man rührt  einige Zeit und filtriert das ausgeschiedene       Anil:  



  Process for the production of a new intermediate product in the dye industry. It has been found that a new intermediate product, the p-dimethylaminoanil of 1,2-anthracene thioisatin, is obtained if the 1,2-anthracene oxythiophene is condensed with nitrosodimethylaniline. The p-dimethylaminoanil of 1,2-anthracenthioisatin forms a brown-violet powder that is very sparingly soluble in low-boiling solvents.

   It dissolves in concentrated sulfuric acid with an olive-brown color. The. new compound is used to make dyes.



  <I> Example: </I> 75 parts of 1,2-anthracenogythiophene are added to a mixture of 1500 parts of alcohol and 33 parts of 30% sodium hydroxide solution, heated to 40 'and then mixed with 48 parts of nitrosodimethylaniline, dissolved in 300 parts Alcohol, added. The mixture is stirred for some time and the precipitated anil is filtered:

PATENTANSPRUCH: Verfahren zur Herstellung eines neuen Zwischenproduktes, des p-Dimethylamino- anils des 1,2-Anthracenthioisatins, dadurch gekennzeichnet, dass man das 1,2-Anthracen- oxythiophen mit Nitrosodimethylanilin kon densiert. Das p-Dimethylaminoanil des 1,2- Anthracenthioisatins bildet ein braunviolet tes Pulver, das in niedrig siedenden Lösungs- mitteln sehr schwer löslich ist. PATENT CLAIM: Process for the production of a new intermediate product, the p-dimethylamino anil of 1,2-anthracene thioisatin, characterized in that the 1,2-anthracene oxythiophene is condensed with nitrosodimethyl aniline. The p-dimethylaminoanil of 1,2-anthracenthioisatin forms a brown-violet powder that is very sparingly soluble in low-boiling solvents. Es löst sich in konzentrierter Schwefelsäure mit olive brauner Farbe. Die neue Verbindung wird zur Herstellung von Farbstoffen verwendet. It dissolves in concentrated sulfuric acid with an olive brown color. The new compound is used to make dyes.
