Description

  

  <B>Zusatzpatent</B> zum Hauptpatent Nr. 103217.    Verfahren zur Herstellung eines     Anthracenderivates.       Es wurde gefunden, dass man ein     Anthra-          cenderivat,    die im Hauptpatent     No.    103647  beschriebene     2,3-Anthracenthioglycolkarbon-          säure,    erhält, wenn man     131o1.        2,3-1VIercapto-          anthracenkarbonsäure    mit 1     Mol.    Chloressig  säure in Reaktion bringt.  



  <I>Beispiel:</I>  25 Teile     2,3-Mercaptoanthracenkarbon-          säure,    150 Teile Alkohol, 10 Teile     Choressig-          s        iture    werden unter Rühren mit 18 Teilen       Aetzkali    versetzt. Die zunächst in Lösung  gehende     Mercaptokarbonsäure    kondensiert  rasch und fällt als     Thioglycolkarbonsäure    aus,    während die Temperatur bis auf zirka 70    steigt. Nach einstündigem Rühren wird ab  gesaugt, mit     Alkohol    gewaschen, in zirka  500 Teilen Wasser gelöst, kalt filtriert, heiss  aasgesäuert, abgesaugt, gewaschen und ge  trocknet.



  <B> Additional patent </B> to main patent no. 103217. Process for the production of an anthracene derivative. It was found that an anthracene derivative described in main patent no. 2,3-Anthracene thioglycolcarboxylic acid described 103647, is obtained when 131o1. 2,3-1VIercapto-anthracene carboxylic acid with 1 mol. Chloracetic acid in reaction.



  <I> Example: </I> 25 parts of 2,3-mercaptoanthracene carboxylic acid, 150 parts of alcohol, 10 parts of chloroacetic acid are mixed with 18 parts of caustic potash while stirring. The mercaptocarboxylic acid, which initially goes into solution, condenses rapidly and precipitates as thioglycol carbonic acid, while the temperature rises to around 70. After stirring for one hour, the product is filtered off with suction, washed with alcohol, dissolved in about 500 parts of water, filtered cold, acidified while hot, filtered off with suction, washed and dried.
