General description

Ethylene is an alkene used in Friedel-Crafts alkylation, cycloaddition, electrophilic addition, and vinylation reactions.

Application

Ethylene is mainly used as a precursor to synthesize polyethylene, ethylbenzene and ethylene dichloride. It is also used in the preparation of single- layer graphene by thermal chemical vapor deposition.

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
