      Zusatzpatent    zum hauptpatent     Nr.258590.       Verfahren zur Herstellung eines neuen     Wollfarbstoffes.       Die vorliegende Erfindung betrifft ein  Verfahren zur Herstellung eines neuen     Woll-          farbstoffes,    gemäss     welehenr.        1,1-Diamino-2,3-          di-(p-phenoxyplienoxy)-anthraeh.inon    derart  sulfoniert wird, dass     zwei        Sulfonsäuregruppen     in das Molekül eintreten.  



  Der neue     Farbstoff    ist ein rotviolettes Pul  ver, welches sich in     Wasser    unter Bildung  einer rotvioletten Lösung und in     konz.        Sehwe-          felsäure    unter Bildung einer braunen Lösung  löst.         Beispiel:       2,5 Teile     Kaliurnlivdroxyd    werden in 20  Teilen geschmolzenem     1-Oxydiphenyläther    ge  löst und das so     erhalleue        Gemiseh    zur Ent  fernung des     gebildeten    Wassers auf 1750 C  erhitzt.

   Dann versetzt man     allmählich    mit  5 Teilen     2,3-1)ieldor-1,l-dianiinoanthracliinon     und rührt das     Genfisch    während 17 Stunden  auf 175 bis 1800 C. Hierauf wird das     Genniseh     in     Äthylalkohol        gegossen    und Wasser zuge  setzt. Das auf diese Weise ausgefällte     1,1-Di-          amino    - 2,3 -     di-        (p-phenoxyphenoxy)    -     anthrachi-          non    wird     abfiltriert    und aus     ss-Äthoxyäthaiiol       umkristallisiert.

   Es bildet dunkelviolette Kri  stalle vom     Smp.    192 bis 1930 C.  



  4 Teile der so erhaltenen Base werden in  50 Teilen     98'J        iger    Schwefelsäure gelöst und  die Lösung bei Zimmertemperatur so lange  gerührt, bis eine Probe sich in verdünnter Na  tronlauge vollständig löst. Der erzielte Farb  stoff wird durch Giessen des     Sulfonierungs-          gemisehes    auf Eis und Filtrieren isoliert. Der  Rückstand wird in verdünnter     Ätznatron-          lösung    gelöst und durch Zugabe von Salz er  neut. ausgefällt. Dann. wird der Farbstoff ab  filtriert und getrocknet.



      Additional patent to the main patent number 258590. Process for the production of a new wool dye. The present invention relates to a method for producing a new wool dye, according to Welehenr. 1,1-diamino-2,3-di- (p-phenoxyplienoxy) -anthraeh.inon is sulfonated in such a way that two sulfonic acid groups enter the molecule.



  The new dye is a red-violet powder, which is dissolved in water to form a red-violet solution and in conc. Sulfuric acid dissolves to form a brown solution. Example: 2.5 parts of potassium hydroxide are dissolved in 20 parts of molten 1-oxydiphenyl ether and the resulting mixture is heated to 1750 C to remove the water formed.

   Then gradually 5 parts of 2,3-1) ieldor-1, l-dianiinoanthracliinone are added and the Geneva table is stirred for 17 hours at 175 to 1800 C. The geneseh is then poured into ethyl alcohol and water is added. The 1,1-di-amino-2,3-di- (p-phenoxyphenoxy) -anthraquinone precipitated in this way is filtered off and recrystallized from β-ethoxyethaiiol.

   It forms dark purple crystals with a melting point of 192 to 1930 C.



  4 parts of the base thus obtained are dissolved in 50 parts of 98% sulfuric acid and the solution is stirred at room temperature until a sample dissolves completely in dilute sodium hydroxide solution. The dye obtained is isolated by pouring the sulfonation mixture onto ice and filtering. The residue is dissolved in dilute caustic soda solution and renewed by adding salt. failed. Then. the dye is filtered off and dried.
