Description

  

  Verfahren zur Darstellung eines sauren     Chromierungsfarbstoffes    der     Anthraehinonreihe.       Gegenstand dieses     Zusatzpatentes    'ist ein  Verfahren zur Darstellung eines sauren       Chromierungsfarbstoffes    der     Anthrachinon-          reihe,    welches dadurch gekennzeichnet ist,       dass    man     1-Amino-4-bromanthrachinon-2-          sulfosäure    mit     4'-Amino-4-oxy-2-methyl-          diphenylmethan-5-carbonsäure    kondensiert.

    <I>Beispiel:</I>  380     Gewichtsteile        1-Amino-4-bromanthra-          chinon-2-sulfosäure    und 300 Gewichtsteile       4'-Amino-\4-oxy-2-methyldiphenylmethan.-,5-          carbonsäure    werden in Form ihrer     Natrium-          salze        in,    Wassergelöst und mit 170 Gewichts  teilen     Natriumbicarbonat    und 9 Gewichts  teilen     gupferchlorür    24 Stunden bei 60 bis  <B>615'</B> 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 anthraquinone series, which is characterized in that 1-amino-4-bromoanthraquinone-2-sulfonic acid is mixed with 4'-amino-4-oxy-2-methyldiphenylmethane -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-oxy-2-methyldiphenylmethane .-, 5-carboxylic acid are in the form of their Sodium salts dissolved in water and mixed with 170 parts by weight of sodium bicarbonate and 9 parts by weight of copper chloride for 24 hours at 60 to 615 ° C.

   The resulting blue pulp is absorbed in water and acidified with dilute hydrochloric acid. The separated reaction product can be further purified in the usual way. 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'--Aminoi-,4-oxy-2--methyldiphenylmethan--5- carbonsäure kondensiert. Der so erhaltene Farbstoff färbt Wolle in klaren blauen Tönen, die beim Nach- ohromieren in ein Graugrün von vorzüg lichen Echtheitseigenschaften übergehen. 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 with 4 '- amino, 4-oxy-2 - methyldiphenylmethane - 5-carboxylic acid condensed. The dyestuff thus obtained dyes wool in clear blue tones which, on post-earing, turn into a gray-green with excellent fastness properties. UNTERANSPRUCH: Verfahren nach Patentanspruch, ,dadurch gekennzeichnet, dass man die Kondensation der Reaktionskomponenten durch Erhitzen in Wasser in Gegenwart von Natrium- bicarbonat und gupferchlorür bewirkt. SUBSTANTIAL CLAIM: Process according to patent claim, characterized in that the reaction components are condensed by heating in water in the presence of sodium bicarbonate and copper chloride.
