Potassium Ferrocyanide Properties:
Lemon yellow crystal or powder. Briny, soluble in water, not soluble in ethanol, ether, methyl acetate and liquid ammonia. Its density is 1.882-1.889.
It loses water in crystal if heated up to 70 ° C and produces white dehydrating compound when heated up to 100 ° C. Giving off N2 when burning .
Its solution will decompose to ferric hydrate when meeting light.
Tech Grade Potassium Ferrocyanide Uses:
Used in manufacturing printing and dyeing, paints, inks, dynamite and other chemical reagent, also can be used in pharmaceutical field, metallurgical
industry and antiagglomerating agent for sodium chloride.
