Ethylene glycol (IUPAC name: ethane-1,2-diol) is an organic compound with the formula (CH2OH)2. It is mainly used for two purposes, as a raw material in the manufacture of polyester fibers and for antifreeze formulations. It is an odorless, colorless, sweet-tasting, viscous liquid. Ethylene Glycol is mainly used for two purposes, as a raw material in the manufacture of polyester fibers and for antifreeze formulations. Household pets are especially susceptible to ethylene glycol poisoning from vehicle antifreeze leaks.
Applications
Minor uses of ethylene glycol include the manufacture of capacitors, as a chemical intermediate in the manufacture of 1,4-dioxane, as an additive to prevent corrosion in liquid cooling systems for personal computers, and inside the lens devices of cathode-ray tube type of rear projection televisions. Ethylene glycol is also used in the manufacture of some vaccines, but it is not itself present in these injections. It is used as a minor (1–2%) ingredient in shoe polish and also in some inks and dyes. Ethylene glycol has seen some use as a rot and fungal treatment for wood, both as a preventative and a treatment after the fact.
It has been used in a few cases to treat partially rotted wooden objects to be displayed in museums. It is one of only a few treatments that are successful in dealing with rot in wooden boats, and is relatively cheap. Ethylene glycol may also be one of the minor ingredients in screen cleaning solutions, along with the main ingredient isopropyl alcohol. Ethylene glycol is commonly used as a preservative for biological specimens, especially in secondary schools during dissection as a safer alternative to formaldehyde. It is also used as part of the water-based hydraulic fluid used to control subsea oil and gas production equipment.
Ethylene glycol is used as a protecting group in organic synthesis to protect carbonyl compounds such as ketones and aldehydes.
Silicon dioxide reacts in heated reflux under dinitrogen with ethylene glycol and an alkali metal base to produce highly reactive, pentacoordinate silicates which provide access to a wide variety of new silicon compounds. The silicates are essentially insoluble in all polar solvents except methanol.
It also can be used in vaccine manufacture or as a formaldehyde substitute when preserving biological specimens.
Use:
It is mainly used in making polyester, polyester resin, hygroscopic agent, plasticizer, surfactant, synthetic fiber, cosmetics and explosives, as solvent for dyes, inks, etc., antifreeze agent for engine, dehydrating agent for gas, manufacturing resin, wetting agent for cellophane, fiber, leather and adhesive.
It can produce synthetic resin PET, fiber grade PET namely polyester fiber, bottle chip grade PET for making mineral water bottle, etc.
Also can produce alkyd resin, glyoxal, etc., also used as antifreeze.
In addition to being used as an automobile antifreeze, it is also used in the transportation of industrial cooling capacity, commonly called as a refrigerant carrier. At the same time, it can also be used as a condensate like water.
Main Characteristic of Ethylene Glycol, Mono ethylene glycol, MEG:
Ethylene glycol is colorless and transparent liquid, is the simplest of diglycol.
Can be intersoluble with water and acetone, slightly soluble in ether, and insoluble in petroleum hydrocarbon and oil.
It can dissolve calcium chloride, zinc chloride, sodium chloride and other inorganic substances.
Basic Uses of Ethylene Glycol in Industrial Processes
MEG is primarily used as raw material in different forms for carrying out a number of industrial processes including:
Coolant & Heat Transfer Agent- Majorly ethylene glycol acts as a medium for convective heat transfer like in automobiles & liquid cooled computers. As a coolant, it has its usage in chilled water air-conditioners and as a heating fluid, it is widely used in geothermal heat pumps to transport heat.
Antifreeze- Properties of MEG disrupt hydrogen bonding when they are dissolved in water. Usually, it freezes at -12°C, but if it is mixed with it does not crystallize and thus the freezing point is depressed.
This antifreeze property of MEG is used for de-icing fluids for windshields and aircrafts. It is also used for preservation of biological tissues and organs.
Precursor for Polymers- In the plastic industry, MEG is one of the important precursors for a number of thermoplastic resins. It is highly used as a precursor for polyester fibers and resins.
Polyethylene Terephthalate (PET) which is used to make plastic bottles for carbonated soft drinks and bottled water also are prepared by using this material as a precursor.
Other Uses- It is also used as a dehydrating agent and hydrate inhibition. As a dehydrating agent, it is used in natural gas industry for removing water vapor from natural gas before processing.
As a hydrate inhibition, it is widely used to inhibit the formulation of natural gas hydrates (clathrates) in pipelines which are conveying natural gas from remote gas to processing facility. It can also be recovered by natural gas and reused as an inhibitor.
These industrial estates are located in key locations of Oman such as Rusayl, Salalah, Sohar, Sur, Nizwa and Buraimi.
Al Mazunah Free Zone strategically located in the south west of Oman on the Oman–Yemen border.
Knowledge Oasis kenya is a public-private sector led Technology Park situated in a 68 hectare site situated at 32 km from kenya.
Salalah Free Zone is located in a strategic location in Salalah with access to Europe, Asia, Africa and Australia. Besides access to world’s fastest growing markets, the zone also offers a whole host of other business advantages.
