Ethylene glycol (EG) is an important organic compound and chemical intermediate used in a large number of industrial processes (e.g. energy, plastics, automobiles, and chemicals). Indeed, owing to its unique properties and versatile commercial applications, a variety of chemical systems (e.g., catalytic and
Now, writing in Nature Catalysis, Edward Sargent and co-authors 4 make a step towards the development of new electrochemical processes for the synthesis of ethylene glycol (Fig. 1). Ethylene glycol is a valuable chemical that is used worldwide as an antifreeze and in the synthesis of polymers and solvents.
Ethylene glycol is a meaningful target obtained from cellulose, as about 20 million tons of ethylene glycol is produced annually from ethylene via ethylene oxide in the petrochemical industry.
Table of thermal and physical properties of saturated liquid ethylene glycol: Pure ethylene glycol freezes at about −12 °C (10.4 °F) but, when mixed with water, the mixture freezes at a lower temperature. For example, a mixture of 60% ethylene glycol and 40% water freezes at −45 °C (−49 °F). Diethylene glycol behaves similarly.
Ethylene glycol is mainly used as antifreeze and a precursor to polyethylene terephthalate, and the minor derivatives are glyoxal for cross-linkers, dioxolane for a co-monomer of polyacetals and solvent, and 1,4-dioxane for solvent (Scheme 2.6). Scheme 2.6. Typical formation routes of ethylene glycol and propylene glycol from cellulose.
Because of its high boiling point and affinity for water, ethylene glycol is a useful desiccant. Ethylene glycol is widely used to inhibit the formation of natural gas clathrates (hydrates) in long multiphase pipelines that convey natural gas from remote gas fields to a gas processing facility.

Ethylene glycol (IUPAC name: ethane-1,2-diol) is an organic compound (a vicinal diol ) 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, flammable, viscous liquid. It has a sweet taste, but is toxic in high concentrations. This molecule has been observed in outer space.
