Ethylene glycol is used in the natural gas industry to remove water vapor from natural gas before ethhanediol processing, in much the same manner as triethylene glycol TEG. By using this site, you agree to the Terms of Use and Privacy Policy. Household pets are especially susceptible to ethylene glycol poisoning from vehicle antifreeze leaks.

The caterpillar of the Greater wax moth, Galleria mellonellahas gut bacteria with the ability to degrade polyethylene PE into ethylene glycol. The glycol and water are separated, and ethaneviol glycol recycled. It is mainly used for two purposes, as a raw material in the manufacture of polyester fibers and for antifreeze formulations. 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.

Nsds Sorbitol Galactitol Iditol. It and its toxic byproducts first affect the central nervous systemthen the heart, and finally the kidneys.

So, while providing freeze protection and an increased boiling point, ethylene glycol lowers the specific heat capacity of water mixtures relative to pure water. Upon ingestion, ethylene glycol is oxidized to glycolic acidwhich is, in turn, oxidized to oxalic acidwhich is toxic. Propylene glycol Diethylene glycol Triethylene glycol Polyethylene glycol.

According to most sources, French chemist Charles-Adolphe Wurtz — first prepared ethylene glycol in The oxidative carbonylation of methanol to dimethyl oxalate provides a promising approach to the production of C 1 -based ethylene glycol.


Ethylene oxide reacts with water to produce ethylene glycol according to the chemical equation:.

InCarbide started up the first plant based on Lefort’s process for vapor-phase oxidation of ethylene to ethylene oxide. Ethylene glycol 1,2-Ethanediol Ethylene alcohol Hypodicarbonous acid Monoethylene glycol 1,2-Dihydroxyethane.

Dry gas exits from the top of the tower. They are generally considered safer to use, as propylene glycol does not taste as good [note 1] and is converted in the body to lactic acida normal product of metabolism and exercise. Diatomic Aluminium monochloride Aluminium monofluoride Aluminium monoxide Argonium Carbon monophosphide Carbon monosulfide Carbon monoxide Carborundum Cyanogen radical 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 Silicon monoxide Silicon monosulfide Sodium chloride Sodium iodide Sulfur monohydride Sulfur monoxide Titanium oxide.

Part of the Automobile series. The freezing point depression of some mixtures can be explained as a colligative property of solutions but, in highly-concentrated mixtures such as the example, deviations from ideal solution behavior are expected due to the influence of intermolecular forces. Retrieved from ” https: Large bubbles in cooling passages will be self-sustaining or grow larger, with virtually the complete loss of cooling in that spot.

Ethylene glycol

Ethylene glycol is widely used to inhibit the formation of natural gas clathrates hydrates in long multiphase pipelines that convey natural gas from remote gas fields to a gas processing facility.

Alkanediols Alcohol solvents Household chemicals Hazardous air pollutants Commodity chemicals Vicinal diols. Treating a ketone or aldehyde with ethylene glycol in the presence of an acid catalyst e. Moreover, the injection rate for hydrate suppression is much lower than the circulation rate in a glycol dehydration tower. Ethylene glycol is produced from carbon monoxide in countries with large coal reserves and less stringent environmental regulations.

Other names Ethylene glycol 1,2-Ethanediol Ethylene alcohol Hypodicarbonous acid Monoethylene glycol 1,2-Dihydroxyethane.

It is one of only a few treatments that are successful in dealing with rot in wooden boats, and is relatively cheap. Retrieved 30 June Minor uses of ethylene 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.

From Wikipedia, the free encyclopedia. It has been used in a few cases to treat partially rotted wooden objects to be displayed in museums. Ethylene glycol is commonly used as a preservative for biological specimens, especially in secondary schools during dissection as a safer alternative to formaldehyde. Protective Groups in Organic Synthesis Third ed. Cooling due to other effects such as air draft from fan etc.

Ethylene glycol – Wikipedia

Consumer Specialty Products Association. Retrieved April 25, Wurtz named his new compound “glycol” because it shared qualities with both ethyl alcohol with one hydroxyl group and glycerin with three hydroxyl groups. In other projects Wikimedia Commons.

Byethylene glycol was being used by almost all dynamite manufacturers.
