Isophorone diisocyanate Chemical Properties,Usage,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.

Chemical Properties

Isophorone diisocyanate is a colourless or slightly yellow liquid, with a vapour pressure which is significantly lower than that of tolylene diisocyanate.

Chemical Properties

colourless or slightly yellow liquid

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; hard industrial coatings; manufacture of contact lenses; curing.

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

Isophorone diisocyanate is 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.

Environmental Fate

Isophorone diisocyanate(IPDI) is a synthetic organic chemical, which does not occur naturally in the environment. At room temperature, it is a liquid. It is miscible with alcohol, diglycol, monoethyl ether, ether, acetone, carbon tetrachloride, benzene, chlorobenzene, kerosene, and olive oil.

Toxicity evaluation

The toxicological properties of isocyanates are attributed to the –N=C=O group. The consequence is that in the hydrolysis of IPDI predominantly polyurea molecules are formed with liberation of CO2. The polyurea molecules are insoluble in water. Beside these insoluble main hydrolysis products, there are minor amounts of other hydrolysis products having a low to moderate molecular weight and these are more or less water soluble (e.g., isophorone diamine). The local toxic effect of the substance IPDI is not related to metabolic mechanisms, because it is a simple destruction of membranes due to corrosivity of the substance.

Toxics Screening Level

The initial threshold screening level (ITSL) for isophorone diisocyanate (CAS #4098-71-9) is 0.45 μg/m3 with an 8-hour averaging time.

Waste Disposal

Disposal is by chemical incineration of IPDIsolution in a combustible solvent.
