Definition: “EDC” is the acronym for Ethylene DiChloride, the common name given to the 1,2 Dichloroethane. As derivated from Ethylene it belongs to the first Olefin family. EDC is mostly produced by catalyzed reaction of the Ethylene and Chloride. Comments: EDC is a colorless liquid with a mild odor. It is toxic and extremely flammable. EDC is a good organic solvent but […]
ReadDefinition: In the petrochemical industry “C4” refers to the branch of Olefins which begins with C4…. in their chemical formulas. C4 is used to nominated the Butadiene and all its derivatives Comments: Among the C4 family, the mostly used products are the Butylene isomers such as, Isoprene, Butyl Rubber (BTR), Styrene, Styrene Butadiene Rubber (SBR) and […]
ReadDefinition: The “Polystyrene” belongs to the Aromatics family (BTX) by the Benzene. Polystyrene is a polymer of the Styrene as monomer where the Styrene itself is produced by dehydrogenation from the Ethylbenzene, a combination of Benzene and Ethylene. Comments: Polystyrene is a plastic made by polymerising styrenes. It is made in two types: a “crystal” polystyrene (extremely transparent) and […]
ReadDefinition: “Butadiene” is the head of the C4 olefins family. Butadiene is a gas that condensates at -4.5°C. Mainly produced as byproducts from Ethylene by Ethane by steam cracking at high temperature (900°C), the Butadiene can also be obtained by Butane dehydrogenation or from Ethanol. Comments: Butadiene is mostly converted into Styrene Butadiene or Styrene Butadiene Rubber (SBR) more well known as synthetic Rubber Polybutadiene is also used […]
ReadDefinition: “Propylene” is the common name given to the Propene. It is a gas, not to be confused with the Propane. Propylene may also be called Methylethylene. Comments: From process perspective, the Propylene is a byproduct as produced in parallel of the Ethylene during the cracking operations in the steam cracker as shown in the flowchart above. […]
ReadDefinition: “Rubber” is the common name given to Styrene Butadiene or Styrene Butadiene Rubber (SBR). Comments: Produced out of the butadiene, the C4 Olefins family, either by fraction distillation in refinery either as byproducts of the Ethylene in the steam cracker, the Rubber is mostly used because of its adhesive performances for tyres, sealants, sho soles, coatings.
