Description

General description

Ethylene glycol (EG) is a polyol having a wide range of industrial applications. Its preparation from cellulose has been reported. It can also be produced from fossil fuels (petroleum, natural gas and coal) and biomass-derived resources.

Application

Ethylene glycol has been used as a carrier fluid during the fabrication of shear thickening fluid (composed of nanosized silica particles). It has also been used to compose previtrification and vitrification solutions for the cryopreservation of mouse embryos.

Reagent typically used in cyclocondensation reactions with aldehydes and ketones to form 1,3-dioxolanes.
