6-Amino-1,3-naphthalenedisulfonic acid Use and Manufacturing
It is derived from the hydrolysis of 2-naphthylamine-1, 5, 7-trisulfonic acid. Add sulfuric acid, sodium sulfate and 2-naphthylamine-1, 5, 7-trisulfonic acid to water, keep at 110-120℃ for 4h, cool and filter, wash with sodium sulfate solution, the resulting filter cake is monosodium amino J acid salt.
It is an intermediate for preparing J acid, double J acid, phenyl J acid and scarlet acid
