8-Anilino-1-naphthalenesulfonic acid Use and Manufacturing
Derived from the condensation of aniline and peric acid in the presence of sulfuric acid. The condensation reaction product is distilled under reduced pressure to obtain refined N-phenyl peri-position acid. It is reacted with soda ash, steam distilled, and activated carbon decolorized to obtain N-phenyl peric acid. Raw material consumption quota: weekly acid (95%) 842kg/t, aniline 650kg/t.
