Ethylene Dichloride (EDC)


EDC-StructureEthylene Dichloride (EDC) is a colorless to yellowish liquid with a faint chloroform-type odour. EDC is used primarily in the production of Vinyl Chloride Monomer (VCM).

Qatar Vinyl Company’s EDC is produced by oxychlorination and direct chlorination of Ethylene at our petrochemical complex located in Mesaieed Industrial City (MIC), Mesaieed, Qatar.


  • Molecular weight: 98.96g/mol
  • Boiling point:  83.6 °C
  • Melting point: -36 °C
  • Flash point: 13 °C
  • Vapor pressure: 102.47 hPa @ 25°C
  • Specific gravity of liquid (water=1): 1.2455 @ 20°C
  • Relative vapor density/air: 1 kg/m3 @ 20°C


The largest use for Ethylene Dichloride is in the production of Vinyl Chloride Monomer (VCM). More than half of the total VCM consumption is for construction-related applications, with pipe being the largest single product. Other products made from PVC resins include flooring, packaging film and sheet, and bottles.

Handling and storage

QVC recommends that prior to installing EDC storage facilities, you contact all concerned local government agencies, i.e., fire department, health department, environmental quality, etc. Local requirements may vary and any EDC installation should meet the standards of these agencies.

EDC spills may need to be reported to QVC Emergency No. 4476 5800 (24hrs). Disposal of spill material should be in compliance with local regulations. More information on the safe handling of EDC is in the Material Safety Data Sheet available from QVC:
