Najdluzszy czas trwania patentu do 7 kwietnia 1946 r.W patencie Nr 13493 opisano sposób otrzymywania trwalego na dzialanie chlo¬ ru niebieskiego barwnika kadziowego, w którym otrzymany wedlug pat. niem. Nr 216891 przez traktowanie #-dwuhydro- 1.2.2*.V antrachinonoazyny srodkami la¬ godnie sulfonuj acemi, korzystnie w obec¬ nosci kwasu borowego, niebieski barwnik szeregu antracenowego poddaje sie w roz¬ tworze kwasu siarkowego dzialaniu dwu¬ tlenku manganu lub podobnie dzialajacych srodków utleniajacych.Stwierdzono, ze otrzymuje sie barwnik o takich samych wlasnosciach, gdy czysta trwala na dzialanie chloru Af-dwuhydro- 1.2.2*.1* antrachinonoazyne otrzymana, np. wedlug patentu Nr 1762, poddaje sie tak dlugo dzialaniu srodków lagodnie sulfonu¬ jacych, np. jednowodzianu kwasu siarko¬ wego, korzystnie w obecnosci kwasu boro¬ wego, az próba barwnika, wydzielona przez wlanie roztworu kwasu siarkowego do wody, rozpusci sie praktycznie zupelnie przy ogrzaniu w 20 — 25% wodnym roz¬ tworze pirydyny.Przyklad. Do roztworu 10 czesci od¬ wodnionego kwasu borowego w 150 cze¬ sciach jednowodzianu kwasu siarkowego wprowadza sie przy 30 — 40°C 10 czesci czystej trwalej na dzialanie chloru N-dwu-hy dr o-1.2.2'. 1* antrachinonoazyny, wytwo¬ rzonej np. wedlug przykladu IV patentu Nr 1762,a»ogrzewa, mieszajac dobrze, do 120°C. Przy tej temperaturze miesza sie tak dlugo, az pobrana próba rozpusci sie praktycznie zupelnie w 20 — 25% wodnym roztworze pirydyny, co nastepuje po uply¬ wie okolo 4 — 5 godzin. Otrzymany pro¬ dukt rozpuszcza sie w 1500 czesciach wo¬ dy o temperaturze 60aC i ogrzewa w ciagu i/2 do 1 godziny do zagotowania, dopóki nie nastapi dalsza przemiana pierwotnie zielonawego odcienia na niebieski, poczem odsacza sie osad, plócze ciepla woda i prze¬ rabia w zwykly sposób. Otrzymany barw¬ nik wszystkiemi wlasnosciami odpowiada barwnikowi otrzymanemu wedlug przykla¬ du patentu Nr 13493. PLThe longest term of the patent, until April 7, 1946, Patent No. 13493 describes a method of obtaining a chlorine-stable blue vat dye, in which the obtained according to US Pat. No. 216891 by treating B-dihydro-1.2.2% by treating anthraquinonazine with mildly sulfonating agents, preferably in the presence of boric acid, the blue dye of the anthracene series is subjected to the action of manganese dioxide or similarly acting oxidizing agents It has been found that a dye of the same properties is obtained when the pure chlorine-stable Af-dihydro 1.2.2 * .1 * anthraquinonoazine obtained, e.g. according to the patent No. 1762, is so long subjected to the action of the agents mildly sulfonates, eg sulfuric acid monohydrate, preferably in the presence of boric acid, until the dye test, separated by pouring the sulfuric acid solution into water, dissolves practically completely when heated in a 20-25% aqueous pyridine solution. Example. To a solution of 10 parts of dehydrated boric acid in 150 parts of sulfuric acid monohydrate, 10 parts of pure chlorine-stable N-dihydrate 1.2.2 'are added at 30-40 ° C. 1 * anthraquinoneazine, prepared, for example, according to example 4 of patent No. 1762, until heated to 120 ° C. while stirring well. At this temperature, stirring is carried out until the sample taken is virtually completely dissolved in a 20 - 25% aqueous pyridine solution, which takes about 4 - 5 hours. The product obtained is dissolved in 1500 parts of water at 60 ° C and heated for 1/2 to 1 hour to boil, until the original greenish tinge changes to blue, and the sediment is drained off, the water rushes with warm water rabbi in the usual way. The dye obtained with all properties corresponds to the dye obtained according to the example of patent No. 13493. PL
