Description

Stwierdzono, ze otrzymuje sie zawiera¬ jace siarke barwniki kadziowe, kondensujac 2-arylo-imidy 6-chlorowco-dwuketo-dwuhy- dro-tionaftenów z 3-olksy-4-alkylo-tionafte- nami i ich produktami podstawienia w rdze¬ niu, zwlaszcza takiemi, które w polozeniu 6-podstawione sa chlorowcem, lub odwrot¬ nie 6-chlorowco-3-oksy-tionafteny konden- suje sie z 2-arylo-imidami 4-alkylo-2,3-dwu- keto-dwuhydro-tionaftenów i ich produkta¬ mi podstawienia w rdzeniu, zwlaszcza pod- stawionemi w polozeniu 6. Otrzymane barw¬ niki barwia bawelne z ikadzi podisiarczyno- wej w kolorach od rózowego do czerwone¬ go, dajac prawie takie same jaskrawe bar¬ wy jalk barwniki 4.4'-dwiualkylo-6,6'-dwu- chlorowco-tioinidigo, przewyzszaja je jed¬ nak pod wzgledem trwalosci na swiatlo i wplywy atmosferyczne, Stanowi to znaczny postep techniczny.Przyklad I. 184,5 czesci 6-chloro-3- cksy-tioniaftenu rozpuszcza sie w mniej wiecej 4000 czesciach kwasu octowego lo¬ dowatego i dodaje 364 czesci 4-metylo<-6- chloiro-2,3-dwuhydro-3-ketotionaftenu-2 - (p- dwumetylo-amino) -anilu, które otrzymuje sie np. przez oddzialywanie nitrozo-dwu- metylo-aniliny na alkaliczny roztwór 3-^sy-4-metyl6~6-chlorotionaftenu. Mieszani¬ ne ogrzewa sie przez pewien czas az do u- konczenia tworzenia sie barwnika. Wydzie¬ lony barwnik odsacza sie. Otrzymuje sie w stanie suchym ciemnoczerwony proszek rozpuszczajacy sie w stezonym kwasie siar¬ kowym w kolorze zielonym. Barwi on ba¬ welne z zóltej kadzi na jaskrawy kolor ró¬ zowy z odcieniem niebieskim. Ten sam barwnik otrzymuje sie, wychodzac od 2- arylo-imidu 6-chloro-oksyticnaftenu i kon- densujac go z 3-oksy-4-metylo-6-chlorotio- naftenami.Otrzymuje sie barwnik o podobnych wlasnosciach, gdy zamiast zwiazków chloru uzywa sie odpowiednia pochodna bromu.Przyklad II. Zastepujac w przykladzie I uzyty 3-oksy-4-metylo-6-chloro - tionaften przez 3-oksy-4-metylo-tionaften, otrzymuje sie barwnik barwiacy bawelne na jaskrawy kolor rózowy z odcieniem niebieskim. PLSulfur-containing vat dyes have been found to be obtained by condensing 6-halo-dice-dihydro-thionaphthene 2-arylimides with 3-olxy-4-alkyl thionaphthene and their substitution products at the core. in particular those which are 6-substituted by halogen or, conversely, 6-halo-3-oxy-thionaphthene is condensed with 4-alkyl-2,3-dihydro-thionaphthene 2-arylimides and their substitution products in the core, especially those in position 6. The dyes obtained dyes cotton from the bisulfite vats in pink to red colors, giving almost the same bright color dyes 4.4 '. dialkyl-6,6'-dihalo-thioinidigo, however, in terms of stability to light and atmospheric influences, it is a significant technological advance. Example I. 184.5 parts of 6-chloro-3-cxithionaphthene dissolve about 4,000 parts of glacial acetic acid and 364 parts of 4-methyl-6-chloro-2,3-dihydro-3 -ketothionaphthene-2 - (p-dimethyl-amino) -anil, which is obtained, for example, by the reaction of nitroso-dimethyl-aniline with an alkaline solution of 3-s-4-methyl-6-chlorothionaphthene. The mixtures are heated for some time until the dye formation is complete. The separated dye is filtered off. A dry dark red powder is obtained which dissolves in concentrated green sulfuric acid. It colors the cotton from the yellow vat a bright pink with a tinge of blue. The same dye is obtained by starting from 2-aryl-imide 6-chloro-oxytic naphthene and condensing it with 3-oxy-4-methyl-6-chlorothionaphthene. A dye with similar properties is obtained when instead of chlorine compounds corresponding bromine derivative. Example II. By replacing the 3-oxy-4-methyl-6-chlorothionaphthene used in Example 1 with 3-oxy-4-methyl-thionaphthene, a bright pink color with a blue tinge is obtained. PL
