合成路线:


生产工艺:  英文抄录如下:

    1-Amino-4-bromo-anthraquinone-2-sulfonic acid (40 kg. 100%) as sodium salt is stirred into water 250 litre, ethanol 100 litre, mesidine 916 litre, sodium hydrogencarbonate 30 kg. and glucose 6 kg. are then added to the suspension, which is stirred and heated to 400C., cuprous chloride 1 kg. is added and the temperature raised to 700C. and maintained at 70-750C. for 2 hours. On cooling to 550C., the precipitated dye is filtered, wahed with sodium hydrogencarbonate solution (400 litre, 5%) at 500C., and then dried at 800C. to give a yield of 40 kg. The product dyes wool and nylon in bright reddish-blue hues of good light and wet fastness.
