  <B>Zusatzpatent</B>     zum    Hauptpatent Nr. 252533.    Verfahren zur Herstellung eines     Küpenfarbstoffes.       Es wurde gefunden, dass ein wertvoller       Küpenfarbstoff    hergestellt werden kann,  wenn man     1-Amino-4-benzoylaminoanthrachi-          non    mit dem Säurechlorid der in     4-Stellung     durch eine     Sulfodiäthylamidgruppe    substi  tuierten     Benzol-l-carbonsäure    umsetzt.  



  Der neue Farbstoff bildet rote Kristalle,  löst sich in     konz.    Schwefelsäure mit roter  Farbe und färbt. Baumwolle aus blauvioletter       Küpe    in echten rotorangen Tönen.  



  <I>Beispiel:</I>  In 1800 Teile     Nitrobenzol    werden unter  Rühren 158 Teile     p-[N-diäthyl]-sulfamidben-          zoesäure,    206 Teile     1-Amino-4-benzoylamino-          anthrachinon    und 100 Teile     Thionylchlorid     eingetragen. Nun wird in einer Stunde auf 87  bis 900     erwärmt    und 8 Stunden bei dieser  Temperatur weitergerührt. Man lässt über    Nacht erkalten,     nutscht    ab und wäscht mit  etwa<B>1300</B> Teilen Nitrobenzol nach.

   Das       Nutsehgut    wird zur Entfernung des anhaften  den Nitrobenzols der     Wasserdampfdestillation     unterworfen, hierauf     abgenutscht    und im       Trockenschrank    getrocknet.



  <B> Additional patent </B> to main patent no. 252533. Process for the production of a vat dye. It has been found that a valuable vat dye can be produced if 1-amino-4-benzoylaminoanthraquinone is reacted with the acid chloride of the benzene-1-carboxylic acid substituted in the 4-position by a sulfodiethylamide group.



  The new dye forms red crystals, dissolves in conc. Sulfuric acid with red color and stains. Cotton from a blue-violet vat in real red-orange tones.



  <I> Example: </I> 158 parts of p- [N-diethyl] -sulfamidbenzoic acid, 206 parts of 1-amino-4-benzoylamino-anthraquinone and 100 parts of thionyl chloride are introduced into 1800 parts of nitrobenzene with stirring. It is then heated to 87 to 900 in one hour and stirred for a further 8 hours at this temperature. It is allowed to cool overnight, suction filtered and washed with about 1300 parts of nitrobenzene.

   To remove the adhering nitrobenzene, the Nutsehgut is subjected to steam distillation, then suction filtered and dried in a drying cabinet.
