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. In the plastic industryethylene glycol is an important precursor to polyester fibers and resins.
The relative sweetness of ethylene glycol  and propylene glycol  is discussed in the Merck Index, and neither compound is described as bitter. Therefore, only carbon monoxide, hydrogen, and oxygen are consumed. Protective Groups in Organic Synthesis Third ed. Upon ingestion, ethylene glycol is oxidized to glycolic acidwhich is, in turn, oxidized to oxalic acidwhich is toxic.
Silicon dioxide reacts in heated reflux under dinitrogen with ethylene glycol and an alkali metal base to produce highly reactive, pentacoordinate silicates which provide access to a wide variety of new silicon compounds.
It has been used in a few cases to treat partially rotted wooden objects to be displayed in museums.
Instead of removing water, ethylene glycol can also be used to depress the temperature at which hydrates are formed. Ethylene glycol can be recovered from the natural gas and reused as an inhibitor after purification treatment that removes water and inorganic salts. 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.
The carbon dioxide comes in part from the ethylene oxide production, where a part of the ethylene is completely oxidized. The 1,3-dioxolane protecting group can thereafter be removed by further acid hydrolysis. This results in the operating temperature range for heat-transfer fluids being broadened on both ends of the temperature scale.

The Organic Synthesis Archive. 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.
In DecemberUS antifreeze manufacturers agreed voluntarily to add a bitter flavoring to all antifreeze that is sold in the consumer market of the Msrs.
Ethylene glycol has seen some use as a rot and fungal treatment for wood, both as a preventative and a treatment after the fact. In the United States, semicommercial production of ethylene glycol via ethylene chlorohydrin started in Mscs is also used as part of the water-based hydraulic fluid used to control subsea oil and gas production equipment. 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.

Consumer Specialty Products Association. Ethylene ethanediok is produced from ethylene ethenevia the intermediate ethylene oxide. National Institute for Occupational Safety and Health.
Cooling due to other effects such as air draft from fan etc. The increase in boiling temperature is due to pure ethylene glycol having a much higher boiling point and lower ethnediol pressure than pure water, as is typical with most binary mixtures of volatile liquids. Industrial-grade propylene glycol usually has a slightly bitter or acrid taste due to impurities.
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. Retrieved December 30, Elsevier, Ruthenium catalyzed hydrogenation of dimethyl oxalate to ethylene glycolJ.
In other projects Wikimedia Commons. According to most sources, French chemist Charles-Adolphe Wurtz — first prepared ethylene glycol in It is mainly used for two purposes, as a raw material in the manufacture of polyester fibers and for antifreeze formulations. Wurtz named his new compound ethaneeiol because it shared qualities with both ethyl alcohol with one hydroxyl group and glycerin with three hydroxyl groups.
Retrieved from ” https: Ethylene glycol is also ethanedikl in the manufacture of some vaccinesbut it is not itself present in these injections. Retrieved 30 June The highest yields of ethylene glycol occur at acidic or neutral pH with a large excess of water.
