Anwendungen & Verwendung
Verwenden
Iodine monochloride is used to estimate theiodine values of fats and oils and as a topicalanti-infective (Merck 1996). For determination of iodine absorption number of fats Iodine monochloride is used as a catalyst in organic synthesis. It is the source of electrophilic iodine in the synthesis of certain aromatic iodides.
Herstellung & Synthese
synthetische
Iodine monochloride is prepared by the action of liquid or dry chlorine on astoichiometric quantity of solid iodine. Aqueous solutions of ICl are preparedby passing chlorine gas into a suspension of iodine in moderately stronghydrochloric acid: 5I2 + 4HCl + 3Cl2 → 10ICl + 2H2 Alternatively, iodine monochloride may be made by oxidation of iodine withiodic acid in strong hydrochloric acid solution: 2I2 + HIO3 + 2HCl → 2ICl + 3HIO
