Description

  

      Zusatzpatent    zum Hauptpatent Nr. 130903.    Verfahren zur Herstellung eines neuen Farbstoffes.    Es wurde gefunden, dass man einen neuen       Farbstaff    erhält, wenn man den durch al  kalische Kupplung erhaltenen     Azofarbstoff     aus     diazotiertem        5-Nitro-4-chlor-2-amino-          phenol    und     2-p-Tolylamino-5-oxynaphthalin-          7-sulfosäure    durch Behandlung mit Chrom  acetat und mittelst eines Backprozesses in       Gegenwart    eines mehrwertigen Alkohols in  dessen Chromverbindung übergeführt.  



  Zur Herstellung der     Backkuchen    ist es  zweckmässig, die Lösungen oder     .Suspensionen     der Chromverbindungen der     ehromierbare     Gruppen enthaltenden     Azofarbstoffe    in  Gegenwart des     Chromierungsmittels    zur  Trockne einzudampfen, wobei auch während       .dem        Eindampfen    teilweise     Chromierung    er  folgen kann.  



  Der     erhaltene    Farbstoff löst sich schwer  in Wasser mit blauer Farbe, sehr gut in       verdüniter        Sod.alösung    oder Natronlauge  mit     grünlichblauer    Farbe. In konzentrierter  Schwefelsäure löst .sich derselbe blauviolett.  Baumwolle wird aus neutralem oder schwach    alkalischem Bad in     grünlichblauen    Tönen  angefärbt.  



       Beispiel:     Der Farbstoff, der erhalten wird durch  alkalische Kupplung von 19,8 Teilen     diazo-          tieTtem        5-Nitro-4-chlor-2-aminophenol    mit  32,9 Teilen     2-p-Tolylamino-5-naphthol-7-          sulfosäure    wird als     Natron-salz    in 6000  Teilen heissem Wasser gelöst     resp.    suspen  diert und mit 15,6 Teilen     CrA    in Form  von 9     %igem    Chromacetat und 30 Teilen  Glyzerin versetzt, auf dem Wasserbad zu  einem Brei eingedampft und der Brei nun  24 Stunden .auf<B>160'</B> erwärmt.

   Die Masse  ist nun zu einem schwärzlichen,     bronzigen     Kuchen erstarrt, welcher leicht pulverisiert  werden kann.



      Additional patent to main patent No. 130903. Process for the production of a new dye. It has been found that a new dye is obtained if the azo dye obtained by alkaline coupling is carried out from diazotized 5-nitro-4-chloro-2-aminophenol and 2-p-tolylamino-5-oxynaphthalene-7-sulfonic acid Treatment with chromium acetate and converted into its chromium compound by means of a baking process in the presence of a polyhydric alcohol.



  To produce the baking cakes, it is advisable to evaporate the solutions or .suspensions of the chromium compounds of the azo dyes containing honorable groups to dryness in the presence of the chromating agent, and partial chromating can also occur during .dem evaporation.



  The dye obtained is difficult to dissolve in water with a blue color, very well in dilute soda solution or sodium hydroxide solution with a greenish-blue color. In concentrated sulfuric acid it dissolves in blue-violet. Cotton is dyed in greenish-blue tones from a neutral or slightly alkaline bath.



       Example: The dye which is obtained by alkaline coupling of 19.8 parts of diazo-tieTtem 5-nitro-4-chloro-2-aminophenol with 32.9 parts of 2-p-tolylamino-5-naphthol-7-sulfonic acid is used as Soda salt dissolved in 6000 parts of hot water, respectively. suspended and mixed with 15.6 parts of CrA in the form of 9% chromium acetate and 30 parts of glycerine, evaporated to a paste on a water bath and the paste is now heated to <B> 160 '</B> for 24 hours.

   The mass has now solidified into a blackish, bronze cake, which can be easily pulverized.

PATENTANSPRUCH: Verfahren zur Herstellung eines neuen Farbstoffes, dadurch gekennzeichnet, dass man den durch alkalische Kupplung erhal- tenen Azofarbstoff aus diazotiertem 5-Nitro- 4-chlor-2-aminophenol und 2-p-Tolylamino-5- oxynaphthaIin-7-sulfosäure durch Behand lung mit Chromacetat und mittelst eines Backprozesses in Gegenwart eines mehr wertigen Alkohols in dessen Chromverbin dung überführt. PATENT CLAIM: Process for the preparation of a new dye, characterized in that the azo dye obtained by alkaline coupling from diazotized 5-nitro-4-chloro-2-aminophenol and 2-p-tolylamino-5-oxynaphthalene-7-sulfonic acid is carried out Treatment with chromium acetate and converted into its chromium compound by means of a baking process in the presence of a polyvalent alcohol. Der erhaltene Farbstoff löst sich schwer in Wasser mit blauer Farbe, sehr gut in verdünnter Sodalösung oder Natronlauge mit grünlichblauer Farbe. In konzentrierter Schwefelsäure löst sich derselbe blauviolett. Baumwolle wird aus neutralem oder schwach :alkalischem Bad in grünlichblauen Tönen angefärbt. The dye obtained is difficult to dissolve in water with a blue color, very well in dilute soda solution or sodium hydroxide solution with a greenish-blue color. In concentrated sulfuric acid it dissolves blue-violet. Cotton is dyed in greenish-blue tones from a neutral or weakly alkaline bath.
