タイトルまたは説明

Character:

yellow-green flash crystallization block or sand substance. Soluble in cold and hot water is red and purple, easily soluble in alcohol in red. Encounter sulfuric acid was yellow brown, diluted almost colorless. Its solution with sodium hydroxide fluid shows with red precipitate almost a colourless liquid.

Process:

aniline, of toluidine and adjacent toluidine and nitrobenzene, chlorinated melt together, ferrous oxidation condensation, and then use sulfuric acid dissolution extraction, then after neutralization, salting-out, filtration and dry drawees finished products.  

USES:

used for wool, acrylic, silk, leather etc of dyeing. Acrylic dyeing fastness is good. Can also be used to paper, feathers, straw, bamboo, wood, etc, can also be used to manufacture coloring colour amylum.
