use

Uses are mainly used to produce polyester resins, alkyd resins, plasticizers, antifreezes, and also used in cosmetics and explosives. Used as analytical reagents, chromatographic analysis reagents and capacitor media. Ethylene glycol is the fungicide tebuconazole and oxacin. Intermediate of Myelin.

Ethylene glycol is mainly used to prepare antifreeze for automobile cooling system and to produce polyethylene terephthalate (raw material of polyester fiber and polyester plastic), and it can also be used to produce synthetic resins, solvents, and lubricants. , Surfactants, softeners, humidifiers, explosives, etc.

Ethylene glycol can often be used instead of glycerin, used as a hydrating agent and solvent in the leather and pharmaceutical industries, respectively. Ethylene glycol has a strong solubility, but it is easily metabolized and oxidized to produce toxic oxalic acid, so it cannot be widely used as a solvent.

Adding glycol to the hydraulic fluid can prevent the oil-based hydraulic fluid from corroding the rubber in the system; the water-based hydraulic fluid with glycol as the main component is an incombustible hydraulic fluid, which is used in airplanes and automobiles And high-temperature molding presses. Ethylene glycol has many important derivatives.

Low molecular weight polyethylene glycol (monoethylene glycol, diethylene glycol, triethylene glycol or called diethylene glycol, triethylene glycol, and four Chemicalbook glycol respectively) is actually made by hydration of ethylene oxide A by-product of ethylene glycol.
