Bromine perchlorate is an inorganic chemical compound with the formula BrOClO3. It is a shock and light-sensitive red liquid which decomposes above -20 °C.[1][2]
Preparation and reactions
Bromine perchlorate can be produced from the reaction of cesium perchlorate and bromine fluorosulfate at -20 °C:[1]
- CsClO4 + BrSO3F → BrOClO3 + CsSO3F
Alternatively, it can also be produced by the reaction of chlorine perchlorate and bromine at -45 °C. Bromine perchlorate reacts with hydrogen bromide to regenerate bromine:[1]
- BrOClO3 + HBr → Br2 + HClO4
This compound also reacts with cesium perchlorate, to produce Cs[Br(ClO4)2], and various fluorocarbon halides, to produce fluoroalkyl perchlorates.[3][4]
