Appearamce: Colourless, transparent, no mechanical admixture , liquid. The product is made by direct hydration of ethylene oxide formed in a fixed bed reactor loaded with silver catalyst, using ethylene and oxygen as raw material.

Applications : It can be used to synthesis "Polyester" (Dacron) and other polymers, but also can be used as a film, rubber, plasticizers, desiccant, brake oil, raw materials, it is commonly used in high-boiling point solvent , it can be used as a car radiator antifreeze and aircraft engines of the refrigerant. Ethylene glycol can also be used for cellophane, fiber, leather, adhesives humectant. Glycol by heating the stage steam can be used as a smokescreen, glycol dinitr
