Isophorone diisocyanate Usage And Synthesis
Chemical Properties
colourless or slightly yellow liquid
Uses
Yields polyurethanes with high stability, resistance to light discoloration, and chemical resistance.
Uses
Isophorone diisocyanate (IPDI) is used in theproduction of high-quality coatings, polyurethane paints, and varnishes and as an elastomer for casting compounds..
Uses
Isophorone diisocyanate is used in the manufacture of polyurethane with high stability, resistance to light discoloration and chemical resistance; used in paints and varnishes for hardness, flexibility, abrasion, chemical resistance to chalking and weathering; as an elastomer applicable for casting compounds and mastics to highly flexible textile coatings; foams; hard industrial coatings; manufacture of contact lenses; curing.
Definition
ChEBI: A diisocyanate in which the two isocyanate groups are linked by an isophorone substituent.
General Description
A clear to light-yellow liquid. Slightly denser than water and insoluble in water. Toxic by inhalation and skin absorption. Very irritating to skin. Used to make polyurethane coatings.
Air & Water Reactions
Insoluble in water. Isophorone diisocyanate may be sensitive to moisture.
Reactivity Profile
Isophorone diisocyanate reacts with all substances containing active hydrogen atoms such as water, alcohols, phenols, amines, mercaptans, amides, urethanes and ureas.
Hazard
A severe irritant, toxic by skin absorption.
Health Hazard
Like most other isocyanates, IPDI exhibitsmoderate toxicity via inhalation. The acutetoxic symptoms are somewhat similar tothose of toluene-2,4- diisocyanate and diphenylmethane-4,4'-diisocyanate. Thus thetoxicity of such types is a characteristic ofthe -N=C=O functional group and to agreat extent is independent of the nature ofthe ring.
Inhalation of its vapor can cause bronchitis, asthma, tightness of chest, and dyspnea in humans. Recovery from these effectsmay occur in a short period from a lowconcentration exposure.
IPDI is an irritant to the skin and eyes.Exposure to this compound produces skinsensitization and eczema. Its oral toxicity isvery low.
LC50 value, inhalation (rats): 123 mg/m3/4 hrLD50 value, skin (rats): 1060 mg/m3
There is no report of its carcinogenic orreproductive effects in animals or humans.
Health Hazard
Isophorone diisocyanate is highly toxic by inhalation and moderately toxic through the skin. (Non-Specific -- Isocyanates) People with skin or respiratory problems should avoid exposure.
Fire Hazard
When heated to decomposition, Isophorone diisocyanate emits toxic fumes of nitrogen oxides.
Waste Disposal
Disposal is by chemical incineration of IPDIsolution in a combustible solvent.
