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.
化学的特性
Isophorone diisocyanate is a colourless or slightly yellow liquid, with a vapour pressure which is significantly lower than that of tolylene diisocyanate.
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
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.
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
When heated to decomposition, Isophorone diisocyanate emits toxic fumes of nitrogen oxides.
廃棄物の処理
Disposal is by chemical incineration of IPDIsolution in a combustible solvent.
