Application

Ethylene glycol may be used in the preparation of spiroborate esters by reacting with chiral 1,2-aminoalcohols in the presence of triisopropyl borate. It may also be used as a solvent in the preparation of tris(2,2′-bipyrazyl)ruthenium(II) chloride by the reaction of 2,2′-bipyrazine with ruthenium(III) chloride.

General description

Ethylene glycol is the major component of antifreeze preparations.
