Patent subordinate to main patent no 236390. Process for preparing a new dye of the anthraquinone series. The present patent relates to a -process for the preparation of a novel dye -of the anthraquinone series, according to which the 1-amino-4-bromanthraquinone-2,7-disulfonic acid is condensed with 3-acetylamino -4- (methylcarboxy) -aniline.
The dye thus obtained corresponds to the formula
EMI0001.0013
and dyed wool and them. animal fibers in beautiful greenish blue tones.
Example: Heated at 80 for 8 hours: 15 parts of 1-amino-4-bromanthraquinone-2,7-, sodium disulfonate, 8.4 'parts of 3-acetylamino - 4 - (methylcarboxy) - aniline, . 0.4 part of copper sulphate, 4.8 parts of sodium bicarbonate, 75 parts of water and 5 parts of alcohol. The reaction mass changes from red to greenish blue. When the condensation is complete, the mass is poured into acidulated water and the dye which has separated is filtered off.
The dye thus obtained corresponds to the formula
EMI0001.0027
and dyes wool and animal fibers in beautiful greenish blue tones.
