The oxidative carbonylation of methanol to dimethyl oxalate provides a promising approach to the production of C 1 -based ethylene glycol. Royal Society of Chemistry.
Ethylene glycol is also ethanedjol 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. Mannitol Sorbitol Galactitol Iditol. Ethylene glycol may also be one of the minor ingredients in screen cleaning solutions, along with the main ingredient isopropyl alcohol.

Minor uses of ethylene glycol include the manufacture of capacitors, as a chemical intermediate in the manufacture of 1,4-dioxaneas ethajediol 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 reaction can be catalyzed by either acids or basesor can occur at neutral pH under elevated temperatures. 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. Water was removed by azeotropic distillation to shift the equilibrium to the right.
Ethylene glycol is a high-production-volume chemical ; it breaks down in air in about 10 days and in water or soil in a few weeks. Retrieved December 30, The Rested Dog Inn. Natural gas is dehydrated by ethylene glycol. So, while providing freeze protection and an increased boiling point, ethylene glycol lowers the specific heat capacity of water mixtures relative to pure water.
Antifreeze products for automotive use containing propylene glycol in place of ethylene glycol are available. Ethylene glycol is produced from carbon monoxide in countries with large coal reserves and less stringent environmental regulations.
Industrial-grade propylene glycol usually has a slightly bitter or acrid taste due to impurities. 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.
The ethylene glycol either gains energy from the source lake, ocean, water well or dissipates heat to the sink, depending on whether the system is being used for heating or cooling. Ethylene glycol can be recovered from the natural gas and reused as an inhibitor after purification treatment that removes water and inorganic salts.

The carbon dioxide comes in part from the ethylene oxide production, where a part of the ethylene is completely oxidized.
Moreover, the injection rate for hydrate suppression is much lower than the circulation rate in a glycol dehydration tower.
Alkanediols Alcohol solvents Household chemicals Hazardous air pollutants Commodity chemicals Vicinal diols. In the United States, semicommercial production of ethylene glycol via ethylene chlorohydrin started in Not to be confused with Propylene glycolDiethylene glycolor Glycol. Ethylene glycol is produced from ethylene ethenevia the intermediate ethylene oxide.
The 1,3-dioxolane protecting group can thereafter be removed by further acid hydrolysis. Treating a ketone or aldehyde with ethylene glycol in the presence of an ethanedkol catalyst e.
