Chlorine perchlorate is the chemical compound with the formula Cl2O4. This chlorine oxide is an asymmetric oxide, with one chlorine atom in oxidation state +1 and the other +7, with proper formula ClOClO3. It is produced by the photolysis of chlorine dioxide at room temperature with 436 nm ultraviolet light:
- 2 ClO2 → ClOClO3
Chlorine perchlorate can also be made the following reactions at −45 °C.
- CsClO4 + ClOSO2F → Cs(SO3)F + ClOClO3
Chlorine perchlorate is a pale greenish liquid which decomposes at room temperature.
It is less stable than ClO2 and decomposes to O2, Cl2 and Cl2O6 at room temperature.
Chlorine perchlorate reacts with metal chlorides forming anhydrous perchlorates:
- CrO2Cl2 + 2 ClOClO3 → 2 Cl2 + CrO2(ClO4)2
- TiCl4 + 4 ClOClO3 → 4 Cl2 + Ti(ClO4)4
