Overview of ethylene dichloride and ethylidene Chloride
A brief overview of ethylene Dichloride (EDC): This hydrocarbon is produced primarily by ethane chlorination. Both organic and water-soluble solvents can be used. The optimal boiling temperature for this process is 57.2degC (135.5″F). EDC is produced primarily by the direct chlorination of ethylene. It is soluble in a variety of organic solvents, but not in water. EDC is used in the production process of vinyl chloride monomer (VCM), and is then further processed into polyvinylchloride (PVC), an important plastic material. It is also used as a solvent for different chemicals and as a fumigant for grain.
A brief overview of 1,1-dichloroethane (EDC): Ethylidene Chloride is a colorless, sweet-smelling liquid. C2H4Cl2 is the chemical formula for Ethylidene. Ethane chlorination is one of the primary ways of producing this hydrocarbon from petroleum; organic solvents, as well as water-soluble solvents, may be used, with an optimal boiling temperature being 57.2degC (135.5degF). Ethylidene can also be used to dissolve various resins like cellulose acetate. A brief overview of 1,1 dichloroethane: Ethylidene chloride is a clear, colorless liquid with a sweet smell.
Notably, although both ethylene dichloride and ethylidene (abbreviated EDC) represent different chemical compounds, their abbreviations can often be confused as being interchangeable.

What Is Ethylene Dichloride (EDC)?
Ethylene Dichloride (EDC), commonly referred to as 1,2-dichloroethane, is a chemical compound with the molecular formula C2H4Cl2. It’s a colorless liquid with an unpleasant chloroform-like scent.
EDC is used as an intermediate in the production of vinyl chloride monomer (VCM), which in turn is processed to form polyvinyl chloride (PVC), an extremely versatile plastic material.
EDC is made by directly chlorinating ethylene (C2H4) with the aid of a catalyst and is highly reactive due to the presence of two chlorine atoms attached to its structure. As a result, EDC has an exceptionally high boiling point at around 83.5degC (182.3degF). Furthermore, its solubility in organic solvents but only minor solubility in water makes EDC readily accessible as an organic compound.
PVC feedstocks have long been utilized by industry for the production of PVC plastic, an extremely durable plastic that stands out for its versatility, resistance to chemicals, and weatherproof properties.
EDC can also be used as a solvent for various materials, including fats, oils, waxes, and synthetic materials. Furthermore, it has also been utilized as a grain storage fumigant to combat pest infestation and minimize microbial growth.
Note that EDC must be handled and used according to relevant safety measures and regulations in order to reduce potential health and environmental risks.
What Is Ethylidene Chloride?
Commonly referred to as ethylidene chloride, chloroethane is actually known by another name – ethyl chloride.
Chloroethane (C2H5Cl), with the chemical formula C2H5Cl, is a colorless gas or liquid at room temperature depending on pressure. It possesses a pleasant sweet, ether-like fragrance and is highly flammable.
Chloroethane is widely utilized as a solvent across numerous industries. It can be found in pharmaceutical production, intermediate chemical manufacturing processes and refrigeration operations, refrigerant applications, and aerosol propellant production. Chloroethane was even once an essential part of lead-based gasoline.
Due to potential health and environmental risks associated with chloroethane use, its applications are relatively limited compared to other chlorinated compounds. Production and usage have declined over recent years as concerns about its toxicity and ozone-depleting potential have diminished its production and usage.
Please accept my apology for any confusion caused, and I hope this clears up information regarding ethylidene chloride, more commonly referred to as chloroethane or ethyl chloride.
