Chemical Properties
colourless liquid
Chemical Properties
Hexamethylene diisocyanate is a colorless liquid. Sharp, irritating odor.
Uses
Hexamethylene diisocyanate (HDI) is usedfor the production of polyurethane foam andexceptionally high-quality coatings..
Uses
Chemical intermediate.
Definition
ChEBI: A diisocyanate compound with the two isocyanates linked by a hexane-1,6-diyl group.
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. .
Hazard
Combustible.
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.
Health Hazard
HDI is moderately toxic by inhalation. Inhumans the acute toxic symptoms could bewheezing, dyspnea, sweating, coughing, dif-ficulty in breathing, and insomnia. In addition, this compound can produce irritationof the skin, eyes, nose, and respiratory tract.Chronic exposure may cause obstruction ofairways and asthma.
The lethal concentration for rats frominhalation of this compound for 4 hourswas 60 mg/m3. The oral toxicity of thiscompound was found to be low in testanimals. The toxicity order was much higherwhen given intravenously.
LD50 value, oral (mice): 350 mg/kg
LD50 value, intravenous (mice): 5.6 mg/kg
There is no report of any carcinogenic orteratogenic study for this compound..

There is no report of any carcinogenic orteratogenic study for this compound..
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.
Contact allergens
This diisocyanate compound is used in the manufac ture of various polyurethane products: elastic and rigid foams, paints, lacquers, adhesives, binding agents, synthetics rubbers, and elastomer fibers.
Safety Profile
Poison by inhalation and intravenous routes. Moderately toxic by ingestion and skin contact. Potentially explosive reaction with alcohols + base. When heated to decomposition it emits toxic fumes of NOx. See also CYANATES.
Potential Exposure
Used to make other chemicals, coat ings, and polyurethane. It is also used as a hardener in automobile and airplane paints.
Shipping
UN2281 Hexamethylene diisocyanate, Hazard Class: 6.1; Labels: 6.1-Poisonous materials.
Incompatibilities
May form explosive mixture with air. Isocyanates are highly flammable and reactive with many compounds, even with themselves. Incompatible with oxi dizers (chlorates, nitrates, peroxides, permanganates, per chlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Reaction with moist air, water or alcohols may form amines and insoluble polyureas and react exothermically, releasing toxic, corrosive or flamma ble gases, including carbon dioxide; and, at the same time, may generate a violent release of heat increasing the con centration of fumes in the air. Incompatible with amines, aldehydes, alkali metals, ammonia, carboxylic acids, capro lactum, alkaline materials, glycols, ketones, mercaptans, hydrides, organotin catalysts, phenols, strong acids, strong bases, strong reducing agents such as hydrides, urethanes, ureas. Elevated temperatures or contact with acids, bases, tertiary amines, and acyl-chlorides may cause explosive polymerization. Attacks some plastics, rubber and coatings. Contact with metals may evolve flammable hydrogen gas. May accumulate static electrical charges, and may cause ignition of its vapors. Temperatures above 200℃ can cause polymerization. Attacks copper.
Waste Disposal
Disposal is by chemical incineration of HDIsolution in a combustible solvent.
