Description

  

  Verfahren zur Darstellung eines sauren     Chromierungsfarbstoffes    der     Anthrachinonreihe.       Gegenstand dieses     Zusatzpatentes    ist ein  Verfahren zur Darstellung eines sauren       Chromierungsfarbstoffes    der     Anthraehinon-          reihe,    welches dadurch gekennzeichnet ist,  dass man     1-Amino-4-bromanthrachinon-2-sul-          fosäure    mit     4'-Amino-4-ogy-3-methyldiphe-          nylmethan-5-carbonsäure        kondensiert.     



  <I>Beispiel:</I>  380 Gewichtsteile     1-Amino-4-bromanthra-          chinon-2-sulfosäure    und 300     Gewichtsteile          4'-        Amino-        4-ogy,

  3-methyldiphenylmeth        an--5-          carbonsäure        werden    in     Form.    ihrer Natrium  salze in Wasser -gelöst und mit 170 Gewichts  teilen     Natriumbicarbonat    und 9 Gewichts  teilen     Kupferchlorür    24 Stunden bei 60 bis  65   C     gerührt.    Der     entstandene    blaue     Farb-          stoffbrei        wird    in     Wasser        aufgenommen        und     mit     verdünnter    Salzsäure     

  gesäuert.    Das .aus  geschiedene     Reaktionsprodukt    kann     in    der  üblichen Weise noch     weiter    gereinigt wer  den.     Der        Farbstoff    zieht auf Wolle in kla  ren blauen Tönen, welche beim     Chromieren       in ein Graugrün mit vorzüglichen Echtheits  eigenschaften übergehen.



  Process for the preparation of an acidic chromating dye of the anthraquinone series. The subject of this additional patent is a process for the preparation of an acidic chromating dye of the anthraehinone series, which is characterized in that 1-amino-4-bromoanthraquinone-2-sulphonic acid is combined with 4'-amino-4-ogy-3-methyldiphe- nylmethane-5-carboxylic acid condensed.



  <I> Example: </I> 380 parts by weight of 1-amino-4-bromoanthraquinone-2-sulfonic acid and 300 parts by weight of 4'-amino-4-ogy,

  3-methyldiphenylmethan - 5-carboxylic acid are in the form. Their sodium salts dissolved in water and stirred with 170 parts by weight of sodium bicarbonate and 9 parts by weight of copper chloride for 24 hours at 60 to 65 C. The resulting blue pulp is taken up in water and treated with dilute hydrochloric acid

  leavened. The reaction product separated out can be further purified in the usual manner. The dye pulls on wool in clear blue tones which, when chromed, turn into a gray-green with excellent fastness properties.

Claims (1)

PATENTANSPRUCH: Verfahren zur Darstellung eines sauren Chromierungsfarbstoffes der Anthrachinon- reihe, -dadurch gekennzeichnet, dass man 1 Amino-4-bromanthrachinon-2-sulfosäure mit 4'-Amino-4-oxy-,3-methyldiphenylmethan--5- carbonsäure kondensiert. PATENT CLAIM: Process for the preparation of an acidic chromating dye of the anthraquinone series, characterized in that 1 amino-4-bromoanthraquinone-2-sulfonic acid is condensed with 4'-amino-4-oxy, 3-methyldiphenylmethane - 5-carboxylic acid. Der so erhaltene Farbstoff färbt Wolle in klaren blauen Tönen, die beim Nachchro- mieren in ein Graugrün von vorzüglichen Echtheitseigenschaften, übergehen. UNTERANSPRUCH: Verfahren nach Patentanspruch, dadurch gekennzeichnet, dass man die Kondensation der Reaktionskomponenten durch Erhitzen in Wasser in Gegenwart von Natriumbiear- bonat und Kupferchlorür bewirkt. The dyestuff thus obtained dyes wool in clear blue tones which, on re-chroming, change to a gray-green with excellent fastness properties. SUBSTANTIAL CLAIM: Process according to patent claim, characterized in that the condensation of the reaction components is brought about by heating in water in the presence of sodium carbonate and copper chloride.
