Ethylene Glycol/MEG

Product Description

Ethylene glycol (IUPAC name: ethane-1,2-diol) is an organic compound (a vicinal diol[5]) 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, toxic, viscous liquid.

Product Application

1. Coolant and heat-transfer agent

The major use of ethylene glycol is as an antifreeze agent in the coolant in for example, automobiles and air-conditioning systems

2. Anti-freeze

used as a de-icing fluid for windshields and aircraft, as an antifreeze in automobile engines.

3. Precursor to polymers

In the plastic industry, ethylene glycol is an important precursor to polyester fibers and resins. Polyethylene terephthalate, used to make plastic bottles for soft drinks, is prepared from ethylene glycol.

4. Dehydrating agent

used in the natural gas industry to remove water vapor from natural gas before further processing.

5. Hydrate inhibition

used to inhibit the formation of natural gas clathrates (hydrates)
