Ethylene glycol, also known as glycol, 1,2-ethylene glycol, or EG for short, is the simplest glycol. Ethylene glycol is a colorless, odorless, sweet liquid with low toxicity to animals. Ethylene glycol is miscible with water and acetone, but its solubility in ethers is small. Used as solvent, antifreeze and raw material for synthetic polyester.


MEG : Ethylene glycol is mainly used in the production of polyester polyester, polyester resin, hygroscopic agents, plasticizers, surfactants, synthetic fibers, cosmetics, and explosives. It is also used as a solvent for dyes, inks, etc., as well as an antifreeze agent for preparing engines, gas dehydrating agents, manufacturing resins, and can also be used as a wetting agent for glass paper, fibers, leather, and adhesives.
It can produce synthetic resin PET, fiber grade PET or polyester fiber, and bottle grade PET for making mineral water bottles, etc. It can also produce alkyd resin, glyoxal, etc., and be used as an antifreeze.
 In addition to being used as an antifreeze for automobiles, it is also used for the transportation of industrial cooling capacity, commonly referred to as a refrigerant, and can also be used as a condensing agent like water.

Application Areas


1. Mainly used in the production of polyester resin, alkyd resin, plasticizer, antifreeze, also used in cosmetics and explosives 

2. Used as analytical reagent, chromatographic analysis reagent and capacitor medium 

3. It is mainly used to prepare antifreeze agent for automobile cooling system and produce polyethylene terephthalate (the raw material of polyester fiber and polyester plastic). It can also be used to produce other synthetic resins, solvents, lubricants, and surfaces Active agents, softeners, moisturizers, explosives, etc. Ethylene glycol can often be used instead of glycerin, and is used as a hydrating agent and a solvent in the tanning and pharmaceutical industries, respectively. 

4. Use different oxidants or reaction conditions for ethylene glycol. After oxidation, glycolaldehyde, glyoxal, glycolic acid, oxalic acid, etc. can be obtained.


application

1. Mainly used for making polyester fiber, polyester resin, dehumidifying agents, plasticizers, surfactant, synthetic fibers.



2. Can be used as a dye / ink solvent, the preparation of the engine antifreeze, gas dehydration.




3. For the production of synthetic resin, PET, or polyester fiber grade PET, bottle grade PET film used to produce mineral water bottles.




4. Can also produce alkyd resins, also used as antifreeze.
