ETHYLENE OXIDE 99.5+%

General description

Ethylene oxide is generally synthesized by chlorohydrine process and direct oxidation of ethylene with air, catalyzed by silver(Ag).

Ethylene oxide serves as a starting material to produce ethylene glycols, surfactants, emulsifiers, and polyurethane foams.

Application

Ethylene oxide can be used as a precursor to synthesize:

• Poly(ethylene oxides) and poly(ethyleneglycol)s.
• Ethylene carbonate via coupling reaction with CO₂ catalyzed by imidazolium zinc tetrahalides.;
• α,ω-heterodifunctionalized poly(ethylene oxide)s using organocatalyst N-heterocyclic carbenes via ring-opening polymerization.

Packaging

Supplied in a carbon steel lecture bottle with a CGA180M/CGA110F needle valve installed.

Compatible with the following:

• Aldrich^® lecture-bottle station systems
• Aldrich^® lecture-bottle gas regulators
