Potassium ferricyanide

CAS number : 13746-66-2

Molecular weight :329.24

Molecular formula/chemical symbol :K3.FeC6.N6

Description :
Potassium ferricyanide and that red blood salt. Is deep red rhombic crystal, soluble in water, no special smell, soluble in water, acetone, insoluble in ethanol, 100 copies of water soluble in cold water and a potassium ferricyanide, hot water soluble 77.5 a! Is a strong oxidizing agents, poisonous. And acid reaction formation very toxic gas, the high temperature decomposition into very toxic cyanide.

USES :

1, silver halide color photographic materials flushing bleach. 2, black and white and sensitive material of the reducer. 3, black and white photos adjustable brown bleach. So far as the widely used high temperature fast color flushing process has no use. But color film flushing is still widely used. 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.
