Propylene glycol Diethylene glycol Triethylene glycol Polyethylene glycol. Water was removed by azeotropic distillation to shift the equilibrium to the right. Ethylene glycol is also used in the manufacture of some mssbut it is not itself present in these injections. Therefore, only carbon monoxide, hydrogen, and oxygen are consumed.

The use of ethylene glycol not only depresses the freezing point of aqueous mixtures, but also elevates their boiling point. The caterpillar of the Greater wax moth, Galleria mellonellahas gut bacteria with the ability to degrade polyethylene PE into ethylene glycol. Automobile emissions control Catalytic converter Diesel particulate filter Exhaust manifold Glasspack Muffler.

Ethylene glycol can be recovered from the natural gas and reused as an inhibitor after purification treatment that ethanedill water and inorganic salts. Royal Society of Chemistry. 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.

Large bubbles in cooling passages will be self-sustaining or grow larger, with virtually the complete loss of cooling in that spot. The ethylene glycol either gains energy from the source ethznediol, ocean, water well or dissipates heat to the sink, depending on whether the system is being used for heating or cooling. Natural gas is dehydrated by ethylene etjanediol. This results in the operating temperature range for heat-transfer fluids being broadened on both ends of the temperature scale.

Archived from the original on 28 December The major use of ethylene glycol ethnaediol as a medium for convective heat transfer in, for example, automobiles and liquid-cooled computers.

Ethylene glycol

Retrieved October 11, 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. Ethylene glycol is used as a protecting group for carbonyl groups in organic synthesis. nsds

The 1,3-dioxolane protecting group can thereafter be removed by further acid hydrolysis. It is an odorless, colorless, sweet-tasting, viscous liquid.

Ethylene oxide reacts with water to produce ethylene glycol according to the chemical equation:. In DecemberUS antifreeze manufacturers agreed voluntarily to add a bitter flavoring to all antifreeze that is sold in the consumer market of the US.

Ethylene glycol is commonly used as a preservative for biological specimens, especially in secondary schools during dissection as a safer alternative ethandeiol formaldehyde.

In other projects Wikimedia Commons. In ethanedio plastic industryethylene glycol is an important precursor to polyester fibers and resins. Carbide maintained a monopoly on the direct oxidation process untilwhen the Scientific Design process was commercialized and offered for licenses.

Ethylene glycol – Wikipedia

Ethylene glycol is produced from carbon monoxide in countries with large coal reserves and less stringent environmental regulations. Ethylene glycol 1,2-Ethanediol Ethylene alcohol Hypodicarbonous acid Monoethylene glycol 1,2-Dihydroxyethane. The highest yields of ethylene glycol occur at acidic or neutral pH with a large excess of water.

Because of its high boiling point and affinity for water, ethylene glycol is a useful desiccant. See the article on propylene glycol for more information. Ethylene glycol is produced from ethylene ethenevia the intermediate ethylene oxide. Ethylene glycol is highly toxic. The major byproducts are the oligomers diethylene glycoltriethylene glycoland tetraethylene glycol.

It is one of only a few treatments that are successful in dealing with rot in wooden boats, and is relatively cheap. Ethylene glycol is used in the natural gas industry to remove water vapor from natural gas before further processing, in much the same manner as triethylene glycol TEG. National Institute for Occupational Safety and Health.

It has been used in a few cases to treat partially rotted wooden objects to be displayed in museums. It enters the environment through the dispersal of ethylene glycol-containing products, especially at airports, where it is used in deicing agents for runways and aeroplanes. InCarbide started up the first plant based on Lefort’s process for vapor-phase oxidation of ethylene to ethylene oxide. Archived from the original on July 14, Protective Groups in Ethanedoil Synthesis Ethanedkol ed. Australia, the UK, and seventeen US states as of require the addition of a bitter flavoring denatonium benzoate to antifreeze.
