fused crystal. Melting point 57.2 °c (min). The relative density was 1.071. Boiling point 243. C. Refractive index 5559. Soluble in ethanol and ether, slightly soluble in water.
p-nitrochlorobenzene is used as raw material to carry out methoxylation reaction with methanol and liquid alkali to generate p-nitroanisole, which is then reduced by sodium sulfide. The reaction product is separated and distilled off under reduced pressure to obtain p-Aminobenzoyl ether.
mainly used for the preparation of jujube red base GP, Blue salt VB, phenol AS-RL, phenol AS-SG and other ice dye and the equality of medicine.
