Methyl thiocyanate Chemical Properties,Usage,Production

Chemical Properties
General Description
Colorless liquid and an odor of onions. Used as an agricultural insecticide, a fumigant and as a research chemical. No evidence of commercial production in the U.S.
Air & Water Reactions
Very slightly soluble in water [Merck].
Reactivity Profile
Methyl thiocyanate is a moderately toxic liquid, flammable. Violent, possibly explosive oxidation reaction when mixed with chlorates, nitrates, nitric acid, organic or inorganic peroxides, perchlorates. On contact with mineral acids or acid fumes deadly toxic hydrogen cyanide gas is produced. When heated to decomposition or on contact with mineral acids Methyl thiocyanate emits highly toxic fumes of nitriles, oxides of sulfur and nitrogen [Lewis, 3rd ed., 1993, p. 879, 1234].
Health Hazard
Methyl thiocyanate is highly toxic if ingested. It is a rapidly acting poison.
Fire Hazard
When heated to decomposition, Methyl thiocyanate emits very toxic fumes of oxides of nitrogen and sulfur. (Non-Specific -- Thiocyanates) Incompatible with nitric acid. Violent reactions have occurred when mixed with chlorates, nitrates, nitric acid, organic peroxides, peroxides, potassium chlorate, and sodium chlorate. Methyl thiocyanate is volatile.
