Wie in dem Zusatz - Patent Nr. 76262 dargelegt worden ist, lassen sich in dem Verfahren dieses Patentes und des Zusatz-Patentes Nr. 72685 die daselbst verwendeten wasserlöslichen Farbstoffe aus Dinitroanthrachinonen durch solche aus den Reductionsproducten der letzteren ersetzen.As pointed out in Supplementary Patent No. 76262, the process of this patent and of the supplementary patent no. 72685 the water-soluble ones used therein Dyes from dinitroanthraquinones by those from the Reductionsproducten of replace the latter.
Ein Gleiches gilt nun auch für das Verfahren des Zusatz - Patentes Nr. 71435. Man kann demnach in dem Verfahren dieses Patentes die aus Dinitroanthrachinon nach Angabe des Patent - Anspruchs 2 des Haupt-Patentes mittels einer schwächer rauchenden Schwefelsäure von z. B. 12 pCt. Gehalt an freiem Anhydrid erhaltenen wasserlöslichen blauen Farbstoffe durch die entsprechenden blauen wasserlöslichen Farbstoffe in isolirter Form ersetzen, welche entstehen, wenn man nach dem in der Patentschrift Nr. 87729 beschriebenen Verfahren 1 · 41 Di-o-nitroanthrachinon bezw. rohes, durch Nitriren des Anthrachinone dargestelltes Dinitroanthrachinon zunächst in partielle Reductionsproducte überführt und diese dann mit einer rauchenden Schwefelsäure von schwächerem, z. B. 12 pCt. betragenden Anhydridgehalt mehrere Stunden bei ca. 1300 C. bis zum Eintritt der Wasserlöslichkeit erhitzt.The same now also applies to the process of the addendum - patent no. 71435. One can therefore in the process of this patent the from dinitroanthraquinone according to the specification of the patent - claim 2 of the main patent by means of a weaker fuming sulfuric acid of z. B. 12 pct. Replace the water-soluble blue dyes obtained in the free anhydride content with the corresponding blue water-soluble dyes in isolated form, which arise when 1 · 4 1 di-o-nitroanthraquinone or. crude dinitroanthraquinone, represented by nitrating the anthraquinone, is first converted into partial reduction products and these are then treated with a fuming sulfuric acid of weaker, e.g. B. 12 pct. The amount of anhydride content is heated for several hours at about 130 ° C. until solubility in water occurs.
Das Verfahren ist genau das gleiche, wie es im Patent Nr. 71435, Absatz 2, beschrieben worden ist.The procedure is exactly the same as that described in Patent No. 71435, paragraph 2 has been.
Ferner lassen sich im Verfahren des Zusatz-Patentes Nr. 72685 die dort verwendeten, aus a- oder d- Dinitroanthrachinon durch Erhitzen mit einer schwächer rauchenden Schwefelsäure von z. B. 12 pCt. Gehalt an freiem Anhydrid dargestellten blauen wasserlöslichen Farbstoffe analog dem Verfahren des Patentes Nr. 71435 durch diejenigen wasserlöslichen Farbstoffe in isolirter Form ersetzen, welche nach dem in der Patentschrift Nr. 87729 beschriebenen Verfahren aus durch partielle Reduction der genannten Dinitroanthrachinone entstandenen Reductionsproducten durch Einwirkung der genannten schwächer rauchenden Schwefelsäure dargestellt worden sind.Furthermore, in the process of the additional patent no. 72685 the there used, from a- or d- dinitroanthraquinone by heating with a weaker fuming sulfuric acid of z. B. 12 pct. Content of free anhydride represented blue water-soluble dyes analogously to the process of patent No. 71435 by those water-soluble dyes in isolated form which, according to the process described in patent specification No. 87729, from reduction products formed by partial reduction of the named dinitroanthraquinones by the action of the named weaker ones fuming sulfuric acid.
Die Ueberführung der in oben besprochener Weise dargestellten blauen wasserlöslichen in die zugehörigen in Wasser verhältnifsmäfsig unlöslichen Farbstoffe kann endlich, anstatt durch Erhitzen mit concentrirter Schwefelsäure , selbstverständlich auch nach dem Verfahren des Zusatz-Patentes Nr. 76941 durch Erhitzen mit concentrirter Salzsäure oder verdünnter Schwefelsäure von 500B. oder mit Wasser allein oder mit anderen Säuren, z. B. concentrirter Phosphorsäure, bewirkt werden.The conversion of the blue water-soluble dyes described above into the corresponding water-insoluble dyes can finally, instead of by heating with concentrated sulfuric acid, of course, also according to the procedure of the additional patent No. 76941 by heating with concentrated hydrochloric acid or dilute sulfuric acid of 50 0 B. or with water alone or with other acids, e.g. B. concentrated phosphoric acid.
