Air and Water Reactions:No rapid reaction with air Slow reaction with water or mositure in air
Reactive Group:Amines, Phosphines, and Pyridines
Reactivity Alerts:Polymerizable
Reactivity Profile:CYANAMIDE is the amide of cyanic acid. Non-flammable but combustible (flash point: 140° C). Decomposes on warming above 49° C. Emits toxic fumes of CN- and NOx when heated to decomposition or on contact with acids or acid fumes (Hazardous Chemicals Desk Reference, p. 353 (1987)). Contact with moisture, acids or bases may cause a violent reaction at temperatures above about 40° C. Dry solid may polymerize at temperatures above 122° C. Rapid or explosive polymerization may occur during the evaporation of aqueous solutions. Reacts explosively with strong oxidizing agents and strong reducing agents. Attacks various metals (International Chemical Safety Card).

Handling and StoragePrecautions for safe handling
NO open flames. Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.
Conditions for safe storage, including any incompatibilities
Separated from food and feedstuffs and incompatible materials. See Chemical Dangers. Cool. Store at maximum 20 °C, never exceed 30 °C. Dry. Well closed. Keep in a well-ventilated room. Store only if stabilized. See Notes. Store in stainless steel, polyethylene or polypropylene.The commercial 50% solution produced by Degussa AG is stabilized by a special buffer system to a pH between 4.0 and 4.6. Typically, it contains less than 1.5 % dicyandiamide, less than 0.5% urea, and less than 0.1 % thiourea. This solution is stable for at least 3 months if stored at a temperature below 20 deg C. Prolonged storage leads to an increase in the pH and thus to instability of the solution. If a pH of 5.2 has been reached, the product should be used quickly, above pH 5.5 it should be discarded immediately by mixing it with at least the double volume of water. Otherwise, a thermal runaway reaction leading to temperatures above 100 deg C and potential bursting of the container may occur.
