methyl isothiocyanate usage and synthesis

chemical properties	colourless solid
general description	a colorless liquid with a sharp odor. lethal by inhalation of even small quantities of vapor. does not have odor warning characteristics at low concentrations. do not rely on the sense of smell to warn about the presence of vapors. denser than water. flash point below 20°f. may cause tearing and irritate the eyes, skin, nose and throat.
air & water reactions	highly flammable. methyl isothiocyanate reacts with water to form carbon dioxide and methylamine gases.
reactivity profile	isocyanates and thioisocyanates, such as methyl isothiocyanate, are incompatible with many classes of compounds, reacting exothermically to release toxic gases. reactions with amines, aldehydes, alcohols, alkali metals, ketones, mercaptans, strong oxidizers, hydrides, phenols, and peroxides can cause vigorous releases of heat. acids and bases initiate polymerization reactions in these materials. some isocyanates react with water to form amines and liberate carbon dioxide. polyurethanes are formed by the condensation reaction of diisocyanates with, for example, ethyl glycol.
health hazard	very toxic; probable human oral lethal dose is 50-500 mg/kg, or between 1 teaspoonful and 1 oz. for a 70 kg (150 lb.) person. highly irritating to skin, mucous membrances, and eyes. human oral minimum lethal dose: approximately 1 g/kg.
fire hazard	(non-specific -- pesticide, solid, n.o.s.) methyl isothiocyanate may burn, but does not ignite readily. fire may produce irritating or poisonous gases. when heated methyl isothiocyanate emits very dangerous cyanides and sulfur compounds. do not store below -4f or at elevated temperatures. keep away from sparks.
