Iodcyan is an inorganic chemical compound consisting of the group of the nitriles.

Production and representation

Iodcyan can be obtained by reaction of sodium cyanide with iodine at 0 ° C.

The addition of chlorine to the reaction prevents the reaction of the half of the iodine used in the alkali metal iodides.

Properties

Iodcyan is a non-flammable, sensitive to light, moisture-sensitive white solid with a pungent odor that is soluble in water. He decomposes even at room temperature gradually stronger when heated. He is prone to spontaneous polymerization and sublimated above 45 ° C.

Use

Iodcyanid used by Preparators as a preservative.
