Ethylene : Description and use


The simplest alkene, ethylene is an unsaturated hydrocarbon. It can also be called R1150.
It is a colourless and volatile gas with a sweet odour. Its density is close to that of air with which it forms explosive mixtures. At over 425°C, it catches fire and burns with a clear flame. Heat generated by combustion: 47,200kJ/kg.

Flammability: Ethylene is a highly flammable gas.
Explosiveness: This product can form explosive mixtures with air.

  • Synthesising several polymers and plastic materials
  • Accelerating the ripening of fruit
  • Regulating the growth of plants
  • Welding and cutting metals
  • As a refrigerant
