Isophorone diisocyanate Chemical Properties,Uses,Production
Description
Isophorone diisocyanate (IPDI) (CAS No. 4098-71-9) is a clear to pale-yellow liquid with a camphorlike odor which is insoluble in water and miscible with most common organic solvents. IPDI exists in two conformers, cis and trans. Their reactivities are similar and each conformer is an asymmetrical molecule with the secondary isocyanate group being more reactive than the primary isocyanate group. Since the substance does not contain any groups that might oxidize or spontaneously ignite, it is not expected that IPDI would self-ignite, oxidize, or explode at ambient conditions. The water solubility is approximately 15 mg l-1 at 23 ℃, and hydrolysis with a half-life of about an hour leads to polymers or to the corresponding diamine.
Chemical Properties
Isophorone diisocyanate is a liquid with a vapour pressure which is significantly lower than that of tolylene diisocyanate.
Uses
Isophorone diisocyanate (IPDI) is used in theproduction of high-quality coatings, polyurethane paints, and varnishes and as an elastomer for casting compounds..
Definition
ChEBI: A diisocyanate in which the two isocyanate groups are linked by an isophorone substituent.
Preparation
Isophorone diisocyanate (IPDI) is prepared by the phosgenation of isophorone diamine (l-amino-3-aminomethyl-3,5,5-trimethylcydohexane):
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
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.
