説明
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.

化学的特性
Isophorone diisocyanate is a liquid with a vapour pressure which is significantly lower than that of tolylene diisocyanate.
-
使用
Isophorone diisocyanate (IPDI) is used in theproduction of high-quality coatings, polyurethane paints, and varnishes and as an elastomer for casting compounds..
-
定義
ChEBI: A diisocyanate in which the two isocyanate groups are linked by an isophorone substituent.
-
製造方法
Isophorone diisocyanate (IPDI) is prepared by the phosgenation of isophorone diamine (l-amino-3-aminomethyl-3,5,5-trimethylcydohexane):
-
一般的な説明
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.
-
空気と水の反応
Insoluble in water. Isophorone diisocyanate may be sensitive to moisture.
-
反応プロフィール
Isophorone diisocyanate reacts with all substances containing active hydrogen atoms such as water, alcohols, phenols, amines, mercaptans, amides, urethanes and ureas.
-
危険性
A severe irritant, toxic by skin absorption.
-
健康ハザード
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.
-
火災危険
