Questions And AnswerBack Directory
[Uses]

Iodine trichloride is used in organic synthesis as a chlorinating and iodinating agent to introduce chlorine and iodine into organic compounds producing their halogen derivatives. It also is used as a topical antiseptic.
[Preparation]

Iodine trichloride is prepared by adding iodine to liquid chlorine in a stoichiometric amount:
3Cl2 + I2 → 2ICl3
[Reactions]

Iodine trichloride decomposes on heating at 77°C, forming iodine monochloride and chlorine:
ICl3 →ICl + Cl2
It dissolves in concentrated hydrochloric acid , forming HICl4•4H2O:
ICl3 + HCl + 4H2O → HICl4•4H2O
Iodine trichloride hydrolyzes in water or dilute acids, the products depending upon reaction conditions. This reaction usually is similar to iodine monochloride:
4ICl3 + 6H2O → I2 + 6HCl + 2HIO3 + 3Cl2
It combines with potassium chloride, forming a complex salt, KICl4:
ICl3 + KCl → KICl4
Reaction with acetylene produces chlorovinyl iododichloride, containing two active chlorine atoms attached to the iodine atom:
ICl3 + HC≡CH → ClCH=CHICl2
The above product has many applications in chemical synthesis.
[Toxicity]

Iodine trichloride is highly corrosive. Contact with skin can cause a burn. Vapors are highly irritating to eyes and respiratory tract.
