NO,62 Hongkong Steet, Qingdao, Shandong
M.F.:Na2O2
Appearance: Light yellow powder or granule
CAS No.: ********6
EINECS No.:********4
Properties: The specific gravity is 2.**5 and the
apparent density is 0.5 *0.7g/cm3. It is getting darker when
heating and the melting point **0 °C. It will decompose when the
temperature is **6 °C and will release oxygen, There is a strong
corrosive under high temperature..
Preparation:
Sodium peroxide can be prepared on a large scale by the reaction of
metallic sodium with oxygen at *****0 °C, a process that generates
sodium oxide, which in a separate stage absorbs oxygen:
4 Na + O2 → 2 Na2O
2 Na2O + O2 → 2 Na2O2
This synthesis is no longer of commercial significance since more
efficient routes to hydrogen peroxide have been found.[3] More
specialized routes have been developed. At ambient temperatures
(**0 °C), O2 reacts with a dilute (0.*5.0 mole percent) sodium
amalgam. It may also be produced by passing ozone gas over solid
sodium iodide inside a platinum or palladium tube. The ozone
oxidizes the sodium to form sodium peroxide. The iodine is freed
into iodine crystals, which can be sublimed by mild heating. The
platinum or palladium catalyzes the reaction and is not attacked by
the sodium peroxide.
Uses: pharmaceutical and super oxides as oxygen
generating agent mixture for the aerospace, undersea exploration,
job plateau, mine rescue, fire fighting, submarine navigation and
medical health, Sodium peroxide is also widely used as a bleaching
agent, oxidizing agent, to deodorant, fungicide and mineral
analysis.
