Potassium Cyanide

CAS RN:151-50-8

Reactivities / Incompatibilities

Reacts with water or any acid releasing hydrogen cyanide.
Incompatibilities: acids & acid syrups, alkaloids, chloral hydrate, iodine, metallic salts, permanganates, chlorates, peroxides
Chlorates plus potassium cyanide explode when heated.
A mixture of /potassium cyanide and nitrites/ may cause an explosion.
Nitrogen trichloride explodes on contact with ... potassium cyanide. ...
Hydrogen cyanide and mercury (II) cyanide: The cyanide, /mercury(II) cyanide/, is a friction- and impact-sensitive explosive and may initiate detonation of liquid hydrogen cyanide. Other metal cyanides are similar. /Cyanides/
Mixtures /of mercuric nitrate and potassium cyanide/ exploded when heated, but only if contained in narrow igintion tubes. Formation of nitrite, a more powerful oxidant than nitrate, may have been involved.
Perchloryl fluoride /& potassium cyanide/: Explosive reaction at 100-300 deg C.
... Reaction with ammoniacal silver /following/ heating, shock, /or/ standing /can cause an/ explosion (formation of silver fulminate - self-explosive). ... Heating /of potassium cyanide &/ chromium tetraoxide /can cause an/ explosion.
Cyanide may react with carbon dioxide in ordinary air to form toxic hydrogen cyanide gas. /Cyanide/
Readily oxidized by heating to potassium cyanate in presence of oxygen or easily reduced oxides
Fusion of mixtures of metal cyanides with metal chlorates, perchlorates, or nitrates ... causes a violent explosion. /Metal cyanides/
Contact with acids and acid salts causes immediate formation of toxic and flammable hydrogen cyanide gas. ... /Cyanides/
Strong oxidizers (such as acids, acid salts, chlorates & nitrates) [Note: Absorbs moisture from the air forming a syrup].
