Properties

Water solubility	SOLUBLE IN COLD WATER

Chemical Property/Description:

 

Soluble in hot water and ethanol, slightly soluble in cold water. Aqueous solution and ethanol solution is golden yellow, in case of concentrated sulfuric acid is reddish yellow, dilution produces greenish-yellow precipitate, in case of concentrated nitric is yellowish-amber.

Production method: diazotization  coupled with sodium salicylate: add 100g m-nitro to 400ml hydro acid and 1.5L water, heat and dissolve, cool to 0-5ºC, add 540g sodium  dissolved in water saturated solution. After the diazotization, the heavy Chemicalbook nitrogen salt was slowly added into the 116g saturated sodium salicylate aqueous solution, the temperature was controlled below 15 ° C and the pH was strictly controlled at 6. The mixture was continued for 4h and placed overnight, and the crude product was filtered. The crude product is used for hot water dissolution, add activated carbon and a little  hydroxide, the pH is controlled at 9, filtration, cooling, crystallization is the finished product.
 

Main Uses:
