Ethylene glycol is primarily used in formulating antifreeze for automotive cooling systems and in
the production of polyethylene terephthalate (a raw material for polyester fibers and polyester
plastics). It is also employed in the manufacture of various other synthetic resins, solvents, lubricants,
surfactants, softening agents, humectants, explosives, and more. Ethylene glycol is often used as
a substitute for glycerol, serving as a hydrating agent in the leather industry and as a solvent in the
pharmaceutical industry.
Although ethylene glycol has strong dissolving capabilities, it is easily metabolized and oxidized
into toxic oxalic acid, which limits its widespread use as a solvent. When added to hydraulic fluids,
it prevents rubber components in the system from being eroded by oil-based hydraulic fluids.
Water-based hydraulic fluids, with ethylene glycol as the main component, are non-flammable
and are used in aircraft, automobiles, and high-temperature molding machines.
Ethylene glycol has many important derivatives. Low molecular weight polyethylene glycols
(diethylene glycol, triethylene glycol, and tetraethylene glycol) are actually by-products of ethylene
glycol production through the hydration of ethylene oxide. Diethylene glycol is used as a humectant,
plasticizer, sizing agent, solvent for printing inks, drying agent for natural gas dehydration, and
solvent for aromatic extraction. Diethylene glycol dinitrate, similar to ethylene glycol dinitrate, is
also an important industrial explosive.
High molecular weight polyethylene glycols, ranging from colorless viscous liquids to waxy solids
depending on their molecular weight, are another useful class of derivatives. They serve as
lubricants, moisture retention agents, solvents, and intermediates in the rubber and food industries.
They are also used in cosmetics, as well as in textile and paper processing aids.
Ethylene glycol forms a wide variety of esters, which are widely used as solvents. Ethylene glycol
esters of long-chain fatty acids exhibit surface-modifying properties and can be used alone or with
other surfactants as emulsifiers, stabilizers, dispersants, humectants, foaming agents, and
suspending agents.
The reaction of ethylene glycol with urea produces ethylene urea, which is used in the textile
industry. Ethylene glycol disodium salt reacts with 1,2-dibromoethane to form dioxane, a specialized
solvent.
Depending on the oxidizing agent or reaction conditions, ethylene glycol can be oxidized to yield
glycolaldehyde, glyoxal, glycolic acid, oxalic acid, and other compounds.
