Uses

Primary

  • Industrial chemical

Natural occurrence

  • does not occur naturally

Hazards

  • Extremely flammable

Production

Synthesis

  • Dechlorinate 2-chloroethanol using an alkalai hydroxide:
    HOCH2CH2Cl + NaOH
    {
    →
    warm}
    C2H4O + NaCl + H2O
  • Slightly oxidize ethylene with (limited) air over a silver, copper, iron, or alloy of those at elevated temperatures[1]
    2 C2H4 + O2
    {Ag/Cu/Fe
    →
    150-300°C}
    2 C2H4O
