Ethylene

What is ethylene?

Ethylene gas (IUPAC name: ethene) is a hydrocarbon with the formula C2H4 or H2C = CH2. Ethylene is a colorless flammable gas with a “sweet and musky” odor when pure. Ethylene gas is the simplest alkene (a hydrocarbon with a carbon-carbon double bond).

Ethylene gas is widely used in the chemical industry and its production worldwide (more than 150 million tons in 2016) exceeds that of any other organic compound. Much of this production goes towards polyethylene, a widely used plastic containing polymer chains of ethylene units with different chain lengths. Ethylene gas is also an important natural plant hormone and is used in agriculture to press ripe fruit. The ethylene hydrate is ethanol.

Ethylene is one of the first biogas known to man, the simplest olefin gas. So ethylene gas is very close to our lives, even in our own families.

Ethylene gas properties

Ethylene gas is colorless, odorless, lighter than air, sparingly soluble in water, flammable, and has a sweet musky odor.

Ethylene gas has characteristic chemical reactions such as combustion, addition and polymerization.

The combustion reaction of ethylene

• C2H4 burns in oxygen to produce carbon dioxide and water vapor.
• C2H4 + 3O2 (t°) → 2CO2 + 2H2O

The addition reaction of ethylene

Ethylene gas has a double bond addition reaction with halogens, H2 and acids.

• C2H4 + Br2 → C2H4Br2
• C2H4 + H2 → C2H6
• C2H4 + HBr → C2H5Br

The polymerization of ethylene

Under the right conditions (temperature, pressure, catalysis), C2H4 molecules can combine to form a molecule with a larger size and molecular mass, called polyethylene.
The above reaction is called polymerization. Polyethylene is a solid, insoluble in water, non-toxic. Polyethylene is an important raw material in the plastics industry.

Other chemical reactions of ethylene

Effects with KMnO4:

3C2H4 + 2KMnO4 + 4H2O → 3C2H5(OH)2 + 2KOH + 2MnO2

Substitute reaction with Cl2, Br2 at high temperature:

CH2=CH2 + Cl2 → CH2=CHCl + HCl

Application of industrial ethylene gas in industry, agriculture

Applications of Ethylene in industry such as:

• Used in packaging production
• Transport
• Electronics
• Textile industry
• Materials for coatings and adhesives
• Raw materials in building materials
• Participate in many reactions that produce chemicals
• Applications in the petrochemical industry
• Derivative Application

For the agricultural sector:

• Ethylene has the ability to increase the growth of plant cells
• Stimulates the germination and growth of plants and trees
• Increase crop productivity, serving the farming and farming industries
• Especially, the most familiar to us is to make fruit trees ripen faster, even ripen evenly, and be more stable than other methods.
