Cas 75-21-8 Industrial Grade ETHYLENEOXIDE

Ethylene oxide (EO) is one of the most simple cyclic ether, which belongs to the heterocyclic compound and is an important petrochemical product. Ethylene oxide at low temperature is a colorless transparent liquid, at room temperature is a colorless with ether stimulate smell gas, gas [1] high vapor pressure, 30 DEG C up to 141kPa. The high vapor pressure determines the epoxy ethane fumigation when strong penetrating power.

Epoxy ethane is following the formaldehyde after the 2nd generation of chemical disinfectants, is still one of the best cold disinfectant, is currently the fourth largest low-temperature sterilization technology (low temperature plasma, low temperature steam and formaldehyde, epoxy ethane, glutaraldehyde) the most important. EO is a simple epoxy compounds and non specificity of alkyl compounds, molecular formula C2H4O, structure type: CH2CH2O. The molecular weight was 44.05.
