CESIUM SUPEROXIDE CsO2

Properties of cesium superoxide CsO2:

The orange-yellow, decomposes on heating without melting, melted by pressurized of O2. Structure has ion (Cs+)(O2(-)). Reacts vigorously with water, acids, ozone, mono- and dioxide carbon, ammonia. Very strong oxidant.

 

Obtaining cesium superoxide CsO2:

Cs → (O2) Cs2O2↓ → (O2, time) CsO2↓ (-50°C, in liquid NH3).

4 CsOH(liquid) + 3O2 = 4 CsO2 + 2 H2O (400°C).

 

Сhemical reactions with cesium superoxide CsO2:

CsO2 → (400-600°C, -O2) Cs2O2 → (640-980°C, -O2) Cs2O.

4 CsO2 + 2 H2O = 4 CsOH + 3 O2↑. (0°C)

2 CsO2 + 2 HCl(diluted, cold) = 2 CsCl + H2O2 + O2↑.

2 CsO2 + 2 H2SO4(anhydrous) = 2 CsHSO4 + O3↑ + H2O (norm. temp.).

CsO2 + O3 = CsO3 + O2 (norm. temp.).

2 CsO2 + 2 NH3 →(time) 2CsOH + N2 + 2 H2O (norm. temp.).

4 CsO2 +2 CO2(humid) = 2 Cs2CO3 + 3O2 (norm. temp.).

2 CsO2 + CO = Cs2CO3 + O2 (30-40°C).
