Product Introduction:

Density 1.880± 0.06g /cm3(Predicted)

Acidity coefficient (pKa)-0.83±0.40(Predicted)

Water solubility 20g/L at 26.4℃

Light brown powder. Slightly soluble in cold water, easily soluble in hot water, soluble in soda ash or caustic soda solution, yellow green with ferric chloride.

Used as an intermediate of azo dyes, reactive dyes and organic pigments, mainly used in the production of cationic dyes, reactive brilliant red K-2G and so on.

It is obtained from 1-naphthylamino-4,6, 8-trisulfonic acid by neutralization, alkali melting and acidification. Naphthylamine-4,6, 8-trisulfonic acid was neutralized with pure lye, and then melted with sodium hydroxide at 178 ℃ -184℃. Then it is obtained by acidizing sulfuric acid at 0.7-0.78MPa for 4h. The resulting product is a beige powder with 80% K-acid content.
