The uses of interhalogen compounds are as follows :
- ICl is used as a halogenating agent and also in the estimation of iodine number of fats and oils.
- In the preparation of polyhalides, interhalogen compounds are used.
- ClF3 and BrF3 are widely used as fluorinating agent. They are used in the separation of 235U isotope by fluorinating.
235U(s) + 3ClF3(I) - 235UF6(g) + 3CIF(g)
- In propellants ClF3 and IF3 are used as oxidisers.
- They are used as non-aqueous solvents.
- The XX’ interhalogen compounds are used as a catalyst for the oxidation of As(III)
