Description
Ethylene (C2H4), also known as ethene, is a colorless, flammable, and slightly sweet-smelling gas that is an important industrial chemical. It is the simplest alkene with a double bond between the two carbon atoms and is widely used in the production of polymers and other organic compounds.Ethylene is the primary raw material for the production of polyethylene, the world's most widely used plastic.It is also used in the synthesis of other chemicals, including ethylene glycol, styrene, and vinyl chloride.
Ethylene is poorly soluble in water but can dissolve in organic solvents such as ethanol, ether, and acetone.Ethylene has a relatively low thermal conductivity, which is typical for nonpolar molecules.The viscosity of ethylene is low, similar to other gases, and decreases with increasing temperature.Ethylene is quite reactive due to its carbon-carbon double bond, readily undergoing addition reactions, polymerization, and oxidation.
Ethylene is a flammable gas and can form explosive mixtures with air. It is important to handle and use ethylene with appropriate safety measures to prevent fires and explosions.Exposure to high concentrations of ethylene can cause symptoms such as dizziness and nausea, and it is classified as a high asphyxiant.
Applications
· In polymerization processes
· In manufacturing of other chemical intermediates
