Description
The disodium salt and caustic soda concentrated solution of Koch acid (1-naphthylamine-3 mine6 and 8-trisulfonic acid) were heated and melted in a pressure heater at about 180-190 ℃, then the melts were dissolved in water and then acidified and precipitated.Slightly soluble in cold water, soluble in alkaline solutions such as soda ash and caustic soda.
With ferric chloride solution was brown red. The acid salt has a bluish red fluorescence, and becomes reddish purple after adding alkali. H acid products are generally paste or powder.
Application
H-acid monosodium salt is mainly used to produce acidic, direct and reactive dyes, such as acid magenta 6B, acid red G, acid black 10B, direct black, reactive brilliant red K-2BP, reactive purple K-3R, active soluble blue More than 90 kinds, these dyes are used for dyeing wool and cotton fabrics. Can also be used to produce drugs.
