Description

1-1звесте -1 способ получени  кислотных красителей антрахиноноБОг-о р да путем конденсации 1-амино-2-сульфо-4бромантрахинона с аминами ароматического р да и пос,1едуюш;им су.тьфированием .1-1, the -1 method of producing anthraquinone-BOB-acid acid dyes by condensation of 1-amino-2-sulfo-4-bromo-methraquinone with amines of the aromatic series and by organic synthesis.

Такие красители обладают  рким синим цветом с красно-ватым оттенком, достаточ Г() црОЧны и представл ют зпачительный практический интерес.Such dyes have a bright blue color with a reddish hue; G () is sufficiently crooked and of great practical interest.

Согласно насто щему изобретению, предлагаетс  дл  получени  такого красител  подвергать сульфированию продукт конденсации 1-амино-2-с льфо-4-бромантрахинона с анилином.According to the present invention, to obtain such a dye, it is proposed to sulfate a condensation product of 1-amino-2-c lfo-4-bromoanthraquinone with aniline.

Получающийс  при этом новый краситель обладает исключительно  рким красновато-синим цветом, превосход щим ализарин непосредстве1П1Ы1 синий ,,А по прочност м к мо-крым обработкам .The resulting new dye has an exceptionally vivid reddish-blue color, superior to alizarin directly P1Y1 blue ,, and in terms of its strength to my treatments.

Пример. 10 г продукта конденсации 1 -амино-2-сульфо-4-бромантрахино )ia с анилином внос т постепенно в 100 гExample. 10 g of the condensation product 1-amino-2-sulfo-4-bromoanthrachino) ia with aniline is gradually introduced into 100 g

моногидрата серной кислоты при температ ре 2(V.

Массу фильтр)пот, осадок промывают :часьпценным раствором по-варенно сол1 и cvHiaT. Вес коасител  18 г.sulfuric acid monohydrate at a temperature of 2 (V. TeNniepaTypa at the same time rises to 40 ° C. Then it is kept sulfomass for 20 minutes at 40% and then poured onto 250 | - ice and salted out by adding dry salty to a 25% brine Mass filter sweat, the precipitate is washed: with an important solution, as described in sal1 and cvHiaT.
