Ethylene oxide reacts with water to produce ethylene glycol according to the chemical equation:.
Ethylene glycol – Wikipedia
Ethylene glycol is also commonly used in chilled-water air-conditioning systems that place either the chiller or air handlers outside, or systems that must cool below the freezing temperature of water. Automobile emissions control Catalytic converter Diesel particulate filter Exhaust manifold Glasspack Muffler.
Retrieved 27 August Treating a ketone or aldehyde with ethylene glycol in the presence of an acid catalyst e. Byethylene glycol was being used by almost all dynamite manufacturers.
Not to be confused with Propylene glycolDiethylene glycolor Glycol. Aluminium monochloride Aluminium monofluoride Aluminium monoxide Argonium Carbon monophosphide Carbon monosulfide Carbon monoxide Carborundum Cyanogen ethanedio Diatomic carbon Fluoromethylidynium Hydrogen chloride Hydrogen fluoride Hydrogen molecular Hydroxyl radical Iron II oxide Magnesium monohydride cation Methylidyne radical Nitric oxide Nitrogen molecular Nitrogen monohydride Nitrogen sulfide Oxygen molecular Phosphorus monoxide Phosphorus mononitride Potassium chloride Silicon carbide Silicon mononitride Ethanediool monoxide Silicon monosulfide Sodium chloride Sodium iodide Sulfur monohydride Sulfur monoxide Titanium oxide.
It msdss the environment through the dispersal of ethhanediol glycol-containing products, especially at airports, where it is used in deicing agents for runways and aeroplanes.

Alkanediols Alcohol solvents Household chemicals Hazardous air pollutants Commodity chemicals Vicinal diols.
Ethylene glycol is produced from ethylene ethenevia the intermediate ethylene oxide. InCarbide started up the first plant based on Lefort’s process for vapor-phase oxidation of ethylene to ethylene oxide.
1-Phenyl-1,2-ethanediol() MSDS Melting Point Boiling Point Density Storage Transport
Minor uses of mss glycol include the manufacture of capacitors, as a chemical intermediate in the manufacture of 1,4-dioxaneas an additive to prevent corrosion in liquid cooling systems for personal computersand inside the lens devices of cathode-ray tube type of rear projection televisions.
This results in the operating temperature range for heat-transfer fluids being broadened on both ends of the temperature scale. Water was removed by azeotropic distillation to shift the equilibrium to the right.
Ethylene glycol is used as a protecting group for carbonyl groups ethanediil organic synthesis. From Wikipedia, the free encyclopedia.
The separation of these oligomers and water is energy-intensive. Protective Groups in Organic Synthesis Third ed.
Retrieved October 11, Retrieved from ” https: Ethylene glycol has seen some use as a rot and fungal treatment for wood, both as a preventative and a treatment after the fact.
The relative sweetness of ethylene glycol  and propylene glycol ethaanediol is discussed in the Merck Index, and neither compound is described as bitter. Molecules detected in outer space. Ethylene glycol is also used in the manufacture of some vaccinesbut it is not itself present in these injections.
The 1,3-dioxolane protecting group can thereafter be removed by further acid hydrolysis. So, while providing freeze protection and an increased boiling point, ethylene glycol lowers the specific heat capacity of water mixtures relative to pure water.
Archived from the original on 28 December Cooling due to other effects such as air draft from fan etc. Household pets are especially susceptible to ethylene glycol poisoning from vehicle antifreeze leaks. Consumer Specialty Products Eghanediol. Ethylene glycol is commonly used as a preservative for biological specimens, especially in secondary schools during dissection as a safer alternative to formaldehyde.
Ethylene glycol is highly toxic. Retrieved 30 June Upon ingestion, ethylene glycol is oxidized to glycolic acidwhich is, in turn, oxidized to oxalic acidwhich is toxic.
Antifreeze products for automotive use containing ethanedol glycol in place of ethylene glycol are available. Because of the depressed freezing temperatures, ethylene glycol is used as a de-icing fluid for windshields and aircraft, as an antifreeze in automobile engines, and as a component of vitrification anticrystallization mixtures for low-temperature preservation of biological tissues and organs.
According to most sources, French chemist Charles-Adolphe Wurtz — first prepared ethylene glycol in It and its toxic byproducts first affect the central nervous systemthen the heart, and finally the kidneys.
The caterpillar of the Greater wax moth, Galleria mellonellahas gut bacteria with the ability to degrade polyethylene PE into ethylene glycol. Pure ethylene glycol has a specific heat capacity about one half that of water. Ingestion of sufficient amounts is fatal if untreated. In this application, ethylene glycol flows down from the top of a tower and meets a rising mixture of water vapor and hydrocarbon gases. Other names Ethylene glycol 1,2-Ethanediol Ethylene alcohol Hypodicarbonous acid Monoethylene glycol 1,2-Dihydroxyethane.
Archived from the original on July 14, Moreover, the injection rate for hydrate suppression is much lower than the circulation rate in a glycol dehydration tower. Therefore, only carbon monoxide, hydrogen, and oxygen are consumed. The highest yields of ethylene glycol occur at acidic or neutral pH with a large excess of water. The formation of large bubbles in cooling passages of internal combustion engines will seriously inhibit heat flow flux from that area, thus allowing nucleation tiny bubbles heat transfer to occur is not advisable.
It has been used in a few cases to treat partially rotted ethaneduol objects to be displayed in museums. Retrieved April 25, Ethylene glycol is produced from carbon monoxide in countries with large coal reserves and less stringent environmental regulations.
