plate-like crystals. Sublimation. Soluble in ethanol, ether, acetic acid and benzene.
first 1,7 A clevulinic acid (1-amino 7 Naphthalene sulfonic acid) with caustic soda fusion to produce 8 amino 2 naphthol sodium salt, and then dilute acid acidification, 8-amino -2-naphthol was precipitated and then acetylated with acetic anhydride to obtain a finished product.
used as an intermediate for coupling components of neutral dyes such as gray, brown, black, and Kappa.
This product is naphthol derivatives, lower than the toxicity of naphthol. On the skin and mucous membranes have a stimulating effect, through the skin absorption and stimulate the kidney caused by nephritis. The workshop should be well ventilated. Production equipment should be closed. Operators should wear protective equipment.

Use | used as neutral dye for gray, brown, black, intermediate for coupling components such as carboplatin This product is an intermediate for coupling combinations of neutral dyes such as gray-brown, black, etc. |
method of production | The first step is to add a mixture of cleific acid (1-amino-7-naphthalenesulfonic acid) alkali Fusion with caustic soda to produce 1-amino -7-naphthol sodium salt, and then dilute acid acidification, so that 1-amino -7-naphthol precipitation, and then acetylated with acetic anhydride: the obtained technical-grade product is a light gray powder or crystal with a purity of more than 95%. Consumption quota: 1964kg/t of cliffic acid, 6500kg/t of solid caustic soda, 6909kg/t of hydrochloric acid (32%), 678kg/t of acetic anhydride (industrial), and 446kg/t of glacial acetic acid (industrial). |
