  Verfahren zur Darstellung von sauren Wollfarbstoffen der Anthrachinonreihe. 



   Es wurde gefunden, dass die Alkalisalze der   Aminoamhrachinonsulfosäuren   durch Erhitzen mit Benzoesäure in neue Farbstoffe übergehen, welche sich von den Ausgangsmaterialien durch bessere Echtheitseigenschaften und eine hellere Nuance auszeichnen. 



   Die Produkte sind identisch mit den im D. R. P. Nr. 223069 (Beispiel 3) beschriebenen   Benzoylaminoanthrachinonsulfosäuren.   Nach dem genannten Patente erfolgt die Einführung des Benzovlrestes durch Einwirkung von Benzoylchlorid auf die freien Amino-   anthrachinonsulfosäuren   in Nitrobenzol als Lösungsmittel und bei Gegenwart einer tertiären Base, wie Pyridin, Dimetylanilin oder Chinolin. 
 EMI1.1 
 Vorteil, da einerseits die Darstellung der freien   Aminoanthrachinousulfosäuren.   die wegen des gleichzeitig sauren und basischen Charakters dieser Körper Schwierigkeiten bereitet und andererseits die Überführung der Benzoesäure in Benzoylchlorid sowie endlich die Anwendung von Lösungsmitteln und   Kontaktscbstanzen   überflüssig gemacht wird. 



   Das Verfahren wird durch folgendes Beispiel erläutert :
1 Teil Natriumsalz der 1-Aminoanthrachinon-6-sulfosäure und 4 Teile Benzoesäure werden einige Stunden auf   40   bis 2500 erhitzt.   Die ebmeizc wird   mit Wasser aufgenommen und solange mit Wasserdampf behandelt,   bis im Destitiat ke : ne Benzoesänre   mehr nachzuweisen ist. Beim Erkalten kristallisiert der im Wasser schwer lösliche Farbstoff in gelben Nädelchen aus.

  Process for the preparation of acidic wool dyes of the anthraquinone series.



   It has been found that the alkali salts of the aminoamhraquinone sulfonic acids, when heated with benzoic acid, are converted into new dyes which are distinguished from the starting materials by better fastness properties and a lighter shade.



   The products are identical to the benzoylaminoanthraquinone sulfonic acids described in D. R. P. No. 223069 (Example 3). According to the patent mentioned, the benzoyl radical is introduced by the action of benzoyl chloride on the free amino anthraquinone sulfonic acids in nitrobenzene as the solvent and in the presence of a tertiary base such as pyridine, dimethylaniline or quinoline.
 EMI1.1
 Advantage because on the one hand the representation of the free aminoanthraquinous sulfonic acids. which causes difficulties because of the simultaneously acidic and basic character of these bodies and, on the other hand, the conversion of benzoic acid into benzoyl chloride and finally the use of solvents and contact substances are made superfluous.



   The procedure is illustrated by the following example:
1 part of the sodium salt of 1-aminoanthraquinone-6-sulfonic acid and 4 parts of benzoic acid are heated to 40-2500 for a few hours. The ebmeizc is absorbed with water and treated with steam until no more benzoic acid can be detected in the destitute. When it cools down, the dye, which is sparingly soluble in water, crystallizes out in yellow needles.
