What is NAPHTHOL AS-GR PURIFIED GRADE?
Preparation
O-Methylaniline?and 3-Hydroxyanthracene-2-carboxylic acid?condensation.
Properties and Applications
dark yellow powder. Insoluble in water, but soluble in butanol and pyridine. In the yellow brown for sulfuric acid solution; Sodium hydroxide solution for the red light in the orange, sodium carbonate in solution not dissolve. Melting point 270 ℃, the air is stable. This product is dyed green render agent, mainly used for dyeing cotton, viscose, general is not used for printing. The high affinity for cotton, coupled with less ability.
