1,2-Dichloroethane is a colorless liquid at room temperature, with a nice odor (similar to chloroform) and a sweet flavor. It is a flammable product (especially at high temperatures) and has a purity of 99.9% EDC

Known as Ethylene Dichloride and abbreviated as EDC, it is the basic raw material to manufacture Vinyl Chloride (PVC chain start).

Manufacture Process: Cubatão Plant

Manufactured and marketed in its liquid form, Dichloroethane is obtained by the reaction between Chloride and Ethylene at a low temperature in the presence of iron and oxygen. Afterwards, the product is purified to eliminate organic and inorganic foreign bodies.

Sodium Hypochlorite Reactor

 Hypochlorite is produced by a reaction between gaseous Chlorine and a Caustic soda solution being cooled down.


EDC Reactor

EDC (Dichloroethane) is obtained through a reaction between liquid chlorine and ethylene (inserted through a tube) and it is purified by distillation.


Hydrochloric Acid Reaction Furnace

Hydrochloric acid is produced by a controlled combustion reaction of Chlorine and hydrogen, followed by absorption in treated water.



Caustic soda is produced by electrolysis and reduced through the evaporation process.



 Then, the Soda is cooled down and stored in tanks, before being shipped.
