What are the Uses of Mono Ethylene Glycol?

uses of mono ethylene glycol

Mono ethylene glycol (ethylene glycol) is a liquid organic chemical compound whose molecular formula is represented by C2H6O2. Although this compound is very simple among the glycol family, it has many important uses in various industries. Mono ethylene glycol is commonly used in many chemical products such as antifreeze and refrigerants. This product prevents car engines from freezing in the cold season and from getting hot in the hot season. This compound is also used as a heat transfer fluid in industrial compressor gas coolers, ventilation systems, and ice skating rinks.

What is Mono Ethylene Glycol Used For?

Since this compound can be used as a raw material in most industries, so its functional range will be very wide, but the main uses of mono ethylene glycol in the industry can be mentioned as follows:

Antifreeze:

As mentioned, one of the most important uses of mono ethylene glycol is its use in the production of antifreeze. MEG is used as an antifreeze and coolant in car radiators due to its low melting and boiling point. This combination also protects the engine from corrosion and moderates the engine heat. Also, in systems that use water as a coolant, ethylene glycol and its family such as propylene glycol are used in situations where it is necessary to prevent water freezing.

MEG in antifreeze

To produce antifreeze based on mono ethylene glycol, a certain amount of this substance is mixed with water and a suitable corrosion inhibitor and repellent. It is better not to use more than 70% of MEG, using corrosion inhibitors in this formulation is necessary.

Polymer Production:

In the plastics industry, mono ethylene glycol is an important intermediate in the production of polyester and resin fibers. Polyethylene terephthalate, which is used in the manufacture of plastic bottles for non-alcoholic beverages and in the production of packaging films, is made from MEG.

Coolant and Heat Transfer Agent:

The main use of this compound is a convective heat transfer. For example, it is used in cars and computers where the cooling fluid is liquid. It is also used in gas compressors, air conditioning in cold water systems, and ice ski slopes.

Oil and Gas Industry:

In the oil and gas industry, this substance is used as a thermodynamic inhibitor. This compound is added to natural gas to prevent the formation and freezing of water molecules in gas lines and thus prevent corrosion of gas pipelines.

MEG in the oil and gas industry

Moisture Absorption:

As mentioned, this material is completely miscible with water and has a high ability to absorb moisture. This feature is used in fiber refining in the textile industry, paper industry, production of adhesives and inks. It is also used in gas systems to absorb gas moisture.

Fiberglass:

This compound is used in the manufacture of fiberglass, which is used in cases such as jet skis, bowling balls, storage tanks, and bathtubs.

Wood Care:

This chemical is used to protect and prevent rot or fungus in wood. This advantage is especially useful for museums where wooden and semi-rotten objects are displayed.

Making Ink:

This compound helps to increase the viscosity and reduce the volatility of the ink.

Conclusion:

Note that since the main application of this compound is in the manufacture of antifreeze and anti-boiling, its consumer market will be very growing in the fall. It should be noted that the use of this compound in equipment related to drinking water and the production of medicines and cosmetics is prohibited.

    What is the freezing point of mono ethylene glycol solution?

    1. china chemicals says:

      Pure mono ethylene glycol freezes at about -12 ° C, but when mixed with water, the mixture freezes at a lower temperature.

  2. Sarah says:

    Why is mono ethylene glycol superior to other antifreeze?

    1. china chemicals says:

      One of the advantages of using this compound in antifreeze is its better heat transfer properties than other chemical compounds used such as propylene glycol. In addition, the material has a lower viscosity than PG at zero temperature. The high viscosity of other materials can lead to higher energy consumption and increased costs.
