Mono ethylene glycol (MEG)

What is Mono ethylene glycol

Mono ethylene glycol (MEG), by far the largest volume glycol, is produced by the direct hydration of ethylene oxide (EO). Smaller amounts of DEG and TEG are co-produced in this process, although additional quantities of DEG and TEG can be produced by further reacting MEG with additional EO.

The three ethylene glycols are colourless, essentially odourless stable liquids with low viscosities and high boiling points and have many similar chemical properties. Differences in their applications are due mainly to variations in physical properties such as viscosity, hygroscopicity and boiling point.

Glycols are widely used in industry because of their high boiling points, hygroscopicity, non-corrosiveness, freeze point depression, lubricating, plasticising and solvent properties. Additionally, their ease of chemical reaction, due to their alcohol end groups, makes them popular intermediates in the formation of numerous esters.

Mono ethylene glycol is a chemical substance that is produced by the reaction of ethylene or ethylene oxide for your information Mono ethylene glycol is miscible in ethanol, acetone and water.

It is used as a corrosion inhibitor in antifreeze and in coolants, and in the manufacturing of polyester.

Actualy Mono-ethylene glycol – or MEG – is a vital ingredient for the production of polyester fibres and film, polyethylene terephthalate (PET) resins and engine coolants.
