Description
Verfahren zur Darstellung eines Ogazins der Anthrachinonreihe. Gegenstand des vorliegenden Zusatz patentes ist ein Verfahren zur Darstellung eines Oxazins der Anthrachinonreihe, welches dadurch gekennzeichnet ist,
dass man 1-jod- anthrachinon-2-sulfosaures Natrium mit 3 amino - 4 - oxydiphenylsulfon-ss'-sulfosaurem Natrium in Gegenwart eines säurebindenden Mittels kondensiert und das Kondensations- produkt bis zum Eintritt einer weiteren Sulfrngruppe srulfiert. <I>Beispiel:
</I> 56 Gewichtsteile 1-jodanthrachinon-2-sul- fosaures Natrium, 40 Gewichtsteile 3-amino- 4-oxydiphenylsulfon-3'-sulfosaures Natrium, 2ä Gewichtstele Natriumca"rbonat, 1<B>,</B>5 Ge wichtsteile Natriumbicarbonat, 2 Gewichts teile gupferchlorür und 700 Gewichtsteile Wasser werden 5 Stunden bei 60 bis 65 C gerührt. Nach dem Erkalten wird das aus geschiedene Kondensationsprodukt abgesaugt und mit Wasser ausgewaschen.
In das so er- haltene Kondensationsprodukt wird zur Ver besserung seiner Wasserlöslichkeit eine wei tere Sulfogruppe eingeführt. Zu diesem Zweck wird das getrocknete Produkt in der zehnfachen Gewichtsmenge 5 % igen Oleums so lange bei 15 bis 20 C gerührt, bis eine in Wasser gegossene Probe leicht löslich gewor den ist. Ist dies der Fall, so wird auf Wasser gegossen, abgesaugt, mit verdünnter Koch- salzlösung neutral gewaschen und getrocknet.
Man erhält ein violettes Pulver, welches aus saurem Bade Wolle in violetten Tönen färbt.
Process for the preparation of an ogazine of the anthraquinone series. The subject of the present additional patent is a process for the preparation of an oxazine of the anthraquinone series, which is characterized by
that 1-iodo-anthraquinone-2-sulphonic acid is condensed with 3-amino-4-oxydiphenylsulphone-ss'-sulphonic acid sodium in the presence of an acid-binding agent and the condensation product is sulphated until a further sulphon group enters. <I> example:
56 parts by weight of 1-iodanthraquinone-2-sulphonic acid, 40 parts by weight of 3-amino-4-oxydiphenylsulphone-3'-sulphonic acid sodium, 2 parts by weight of sodium carbonate, 1, 5 ge parts by weight of sodium bicarbonate, 2 parts by weight of gupferchlorur and 700 parts by weight of water are stirred for 5 hours at 60 to 65 ° C. After cooling, the condensation product which has separated out is filtered off with suction and washed out with water.
A further sulfo group is introduced into the condensation product obtained in this way to improve its solubility in water. For this purpose, the dried product is stirred in ten times the weight of 5% oleum at 15 to 20 C until a sample poured into water is easily soluble. If this is the case, it is poured onto water, filtered off with suction, washed neutral with dilute sodium chloride solution and dried.
A violet powder is obtained which dyes wool in violet shades from an acid bath.
