CAS number : 14459-95-1
Molecular weight :422.36
Molecular formula/chemical symbol :K4.Fe(CN)6.3(H2O)
Description :
Yellow powder or crystal, soluble in water,
insoluble in alcohol. A slight weathering. Sixty ℃ at the start of dehydrate,
heated to 70 ℃, 100 ℃ lose water of crystallization into anhydride. Soluble in
5 copies of water, soluble in acetone, insoluble in ethanol and ether, ethyl
acetate, liquid ammonia. The solution in the light and air easy metamorphism,
not with hot acid and concentrated acid hybrid or solution in the sun, in case
produce hydrogen cyanide. In the solution containing about 0.2% potassium
carbonate, but stable for months. Low poison, median lethal dose (rats, through
the mouth) 1600-3200 mg/kg.
USES :
Mainly used in the manufacture of paint, ink, pigments, pharmaceutical, metal heat treatment, salt anticaking agent, food additives, as well as iron and steel industry and knead leather and so on.
