1,6-diisocyanatohexane usage and synthesis

chemical properties	colourless liquid
general description	a colorless crystalline solid. toxic by ingestion and is strongly irritating to skin and eyes. 1,6-diisocyanatohexane is used to make nylon.
air & water reactions	contact with moisture or temperatures over 399°f may cause polymerization. soluble in water.
reactivity profile	1,6-diisocyanatohexane reacts with water. base-catalyzed reactions of 1,6-diisocyanatohexane with alcohols may be explosively violent in the absence of diluting solvents. 1,6-diisocyanatohexane is incompatible with strong bases, amines, acids and strong oxidizers. 1,6-diisocyanatohexane is also incompatible with metal compounds and surface active materials. .
health hazard	toxic; inhalation, ingestion or contact (skin, eyes) with vapors, dusts or substance may cause severe injury, burns or death. contact with molten substance may cause severe burns to skin and eyes. reaction with water or moist air will release toxic, corrosive or flammable gases. reaction with water may generate much heat that will increase the concentration of fumes in the air. fire will produce irritating, corrosive and/or toxic gases. runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
fire hazard	combustible material: may burn but does not ignite readily. substance will react with water (some violently) releasing flammable, toxic or corrosive gases and runoff. when heated, vapors may form explosive mixtures with air: indoors, outdoors and sewers explosion hazards. most vapors are heavier than air. they will spread along ground and collect in low or confined areas (sewers, basements, tanks). vapors may travel to source of ignition and flash back. contact with metals may evolve flammable hydrogen gas. containers may explode when heated or if contaminated with water.
