Ethylene glycol is mainly used in the preparation of antifreeze agents for automotive cooling systems and the production of polyethylene terephthalate (polyester fiber and polyester plastic raw materials), and can also be used in the production of its synthetic resins, solvents, lubricants, surfactants, softeners, humidifiers, explosives, etc. Ethylene glycol is often used in place of glycerin as a water mixture and solvent in the tannery and pharmaceutical industries, respectively. Ethylene glycol has a strong ability to dissolve, but it is easy to metabolize and oxidize to produce toxic oxalic acid, so it cannot be widely used as a solvent. The addition of ethylene glycol to hydraulic fluid can prevent the erosion of rubber in the system by oil-based hydraulic fluid; Water based hydraulic fluid with ethylene glycol as the main component is a non-combustible hydraulic fluid, which is used in aircraft, automobiles and high-temperature operation of the mold press. Ethylene glycol has many important derivatives. Low molecular weight polyethylene glycol (ethylene glycol, diethylene glycol, triethylene glycol, or diethylene glycol, triethylene glycol, tetraethylene glycol, respectively) is actually a by-product of ethylene glycol prepared from ethylene oxide. Diethylene glycol can be used as humidifier, plasticizer, sizing agent, printing ink solvent, natural gas dehydration desiccant and aromatic extraction solvent. Diethylene glycol dinitrate is similar to glycol dinitrate and is also an important industrial explosive. High molecular weight polyethylene glycol is also a useful derivative, depending on the molecular weight, from colorless transparent viscous liquid to waxy solid. Used as lubricants, moisture retention agents, solvents and intermediates in the rubber and food industries, as well as additives in the preparation of cosmetics and textile, paper and other fields. There are many varieties of ethylene glycol esters and they are widely used as solvents. Ethylene glycol esters of long chain fatty acids have surface improvement properties and can be used alone or in combination with surfactants as emulsifiers, stabilizers, dispersants, humidifiers, foaming agents and suspension agents. Ethylene glycol reacts with urea to form ethylene urea, which is used in the textile industry. Glycol disodium reacts with 1, 2-dibromoethane to form dioxane, a special solvent. Different oxidants or reaction conditions are used for ethylene glycol. Glycolaldehyde, glyoxalic acid, glycolic acid and oxalic acid can be obtained after oxidation.
