Description

  

  Verfahren zur Darstellung eines     Chromierungsfarustoffes.       Gegenstand dieses Zusatzpatentes ist ein  Verfahren zur Darstellung eines     Chromie-          rungsfarbstoffes,    welches dadurch gekenn  zeichnet ist, dass man     5-Oxybenzol-1.2.4-          tricarbonsäureanhydrid    mit     2-Methyl-3.4-          benzochinolin    kondensiert und das so er  haltene Produkt mit einem     sulfierend    wirken  den Mittel behandelt.

           Beispiel:       50 Gewichtsteile 2     -Methyl    - 3. 4 -     benzo-          chinolin    und 53 Gewichtsteile     5-Oxytrimellith-          säureanhydrid    werden in Gegenwart von 32  Gewichtsteilen Chlorzink bei 220-230o C  bis zum Erstarren der Schmelze verschmol  zen. Das Kondensationsprodukt wird nach  Auskochen mit 500 Gewichtsteilen 3     o/oiger     Salzsäure, Waschen und Trocknen aus der  30fachen Gewichtsmenge siedendem,     techni-          sc'        --m        Chinolin    umgelöst.

   Es stellt eine gelbe,  amorphe Substanz dar, die sich bei     300'    C  unter Aufschäumen und Dunkelfärbung zer-    setzt. Die Lösungsfarbe in konzentrierter  Schwefelsäure ist rot, in     Sodalösung    gelb, in  Natronlauge orangerot. Das     Mononatriumsalz     ist in kaltem Wasser ziemlich schwer lös  lich und kommt aus der heissen,     wässrigen     Lösung beim Erkalten als Gallerte heraus.

    Die Konstitutionsformel ist  
EMI0001.0024     
    Die     Monosulfosäure    dieser Verbindung erhält  man durch Erhitzen mit der     10-15fachen     Gewichtsmenge 20     o/oigem        Oleum    auf 120 o C  bis zur völligen Wasserlöslichkeit und Ein  giessen der schwefelsauren Lösung in Eis  wasser. Nach dem     Aussalzen    der abgesaug-           ten,    in wenig heissem Wasser gelösten gallert  artigen     Sulfosäure    mit Kochsalz liegt ein  gelber Farbstoff vor, der Wolle schön gelb  färbt und durch     Nachchromieren    in seinen       Echtheiten    wesentlich verbessert wird.



  Process for the preparation of a chromating dye. The subject of this additional patent is a process for the preparation of a chromating dye, which is characterized in that 5-oxybenzene-1,2,4-tricarboxylic anhydride is condensed with 2-methyl-3,4-benzoquinoline and the product thus obtained has a sulfating effect Means treated.

           Example: 50 parts by weight of 2-methyl-3.4-benzoquinoline and 53 parts by weight of 5-oxytrimellitic anhydride are fused in the presence of 32 parts by weight of zinc chloride at 220-230 ° C. until the melt solidifies. The condensation product is redissolved after boiling with 500 parts by weight of 3% hydrochloric acid, washing and drying from 30 times the amount by weight of boiling, technical-grade quinoline.

   It is a yellow, amorphous substance which decomposes at 300 ° C. with foaming and darkening. The solution color in concentrated sulfuric acid is red, in soda solution yellow, in sodium hydroxide solution orange-red. The monosodium salt is rather sparingly soluble in cold water and comes out of the hot, aqueous solution as a jelly when it cools.

    The constitutional formula is
EMI0001.0024
    The monosulfonic acid of this compound is obtained by heating with 10-15 times the amount by weight of 20% oleum to 120 ° C. until it is completely soluble in water and pouring the sulfuric acid solution into ice water. After salting out the suctioned-off gelatinous sulfonic acid dissolved in a little hot water with common salt, a yellow dye is obtained that dyes wool a beautiful yellow and is significantly improved in its fastness properties by subsequent chrome plating.
