Synthesis of iodine trichloride

Preparation of iodine trichloride

Preparation of iodine trichloride from iodine and chlorine

Preparation of iodine trichloride from iodine and chlorine

Preparation of iodine trichloride from iodine and chlorine

20 grams iodine are gently heated in a glass flask connected with a weighed glass balloon filled with 17 g of chlorine. This balloon is further connected (the connection is closed) with a chlorine generator, in order to supply additional chlorine if necessary. The glass flask containing iodine is gently warmed and as soon as the iodine vapors enter the balloon a strong absorption of chlorine takes place, and iodine chloride precipitates against the walls in reddish yellow crystals. When the reaction is complete a current of dry carbon dioxide is led passed through in order to remove an excess of chlorine. Any particles which cannot be removed from the balloon mechanically are dissolved in ten times their weight of water and could be preserved as iodine trichloride solution. Iodine trichloride is a crystalline powder with orange-colored pungent, readily soluble in water and organic solvents.

Preparation of iodine trichloride from iodic acid, iodine and hydrochloric acid

Preparation of iodine trichloride from iodic acid, iodine and hydrochloric acid

Preparation of iodine trichloride from iodic acid, iodine and hydrochloric acid

10.56 g (3 moles) of iodic acid and 5.08 g (1 mole) of resublimed iodine are ground up finely and thoroughly mixed. About twice the theoretical volume (46 ml) of hydrochloric acid (sp. gr., 1.19), is cooled down and the powdered mixture of iodine and iodic acid added in small portions with shaking. Very little chlorine is evolved and the two solids appeared to be taken up at about equal rates. When the mixture have been added and dissolved an orange-yellow solution forms in about 20 minutes. By employing the volume stated each ml of the solution is theoretically equivalent to 0.5 g of iodine trichloride. Iodine trichloride in high concentrations of hydrochloric acid may be kept indefinitely.
