Ethylene glycol is the simplest diol. Ethylene glycol is a colorless, odorless, sweet liquid that is toxic to animals and has a lethal dose of about 1.6 g/kg in humans. Ethylene glycol can be miscible with water and acetone, but its solubility is small in ethers. Used as solvent, antifreeze and raw material for synthetic polyester.

Mainly used in polyester, polyester, polyester resin, hygroscopic agents, plasticizers, surfactants, synthetic fibers, cosmetics and explosives.

And used as dyes, inks and other solvents, preparation of engine antifreeze agent, gas dehydrating agent, manufacturing resin, can also be used for cellophane, fiber, leather, adhesive wetting agent.

Used in producing synthetic resin PET, fiber grade PET is polyester fiber, bottle chip grade PET is used to make mineral water bottles and so on.

It can also be used in producing alkyd resin, glyoxal, etc., and is also used as antifreeze.

In addition to being used as an automotive antifreeze, it is also used for the transportation of industrial cold capacity, generally called as a refrigerant, and can also be used as a condensing agent with water.
