Used to be made from β-naphthylamine. Because of the strong carcinogenicity of β-naphthylamine, this production method has been eliminated, and now 2-naphthylamine-1-sulfonic acid is used as raw material to produce J acid. After sulfonation and hydrolysis, 2-naphthalic acid-5-dimethyl 7-disulfonate monosodium salt (amino J acid) was obtained, which was then neutralized, fused by alkali and acidified. J acid was obtained by sulfonation with fuming sulfuric acid, hydrolysis, absorption, washing, alkali solution and acidizing washing. The sodium salt dissolves in water and shows blue fluorescence. It is co-heated with ferric trichloride solution to form brown-black precipitation.

Chemical property

1. J acid co-heated with ferric chloride solution to form dark brown precipitate; calcium chloride to form yellowish brown precipitate; base sodium salt dissolved in water showed blue fluorescence.

2. Avoid inhaling dust from this product and avoid contact with eyes and skin.

3. poisonous. Rats were given oral LD50:11500mg/kg. Toxic or strongly corrosive raw materials such as 2-aminonaphthalene sulfonic acid, fuming concentrated sulfuric acid and caustic soda are used in production.

Applications

Dye intermediates. It is mainly used to prepare direct green lotus R, direct fast blue FRL, direct fast ash 2BL, direct copper salt blue 2R, direct acid resistant purple, direct pink, direct copper dye navy, fast blue B2R, direct jujube GB, as well as reactive scarlet, orange, brilliant orange X-GN, gray, grass green, red brown and other dyes. It is also used to prepare double J acid, scarlet acid and phenyl J acid.
