Retrieved December 30, Carbide maintained a monopoly on the direct oxidation process untilwhen the Scientific Design process was commercialized and offered for licenses. Ethylene glycol can be recovered from the natural gas and reused as an inhibitor after purification treatment that removes water and inorganic salts.

In the plastic industryethylene glycol is an important precursor to polyester fibers and resins. Ethylene glycol is also used in the manufacture of some vaccinesbut it is not itself present in these injections.

Ethylene glycol is used as a protecting group in organic synthesis to protect carbonyl compounds such as ketones and aldehydes.

Water was removed by azeotropic distillation to shift the equilibrium to the right. The Rested Dog Inn. In this application, ethylene glycol flows down from the top of a tower and meets a rising mixture of water vapor and hydrocarbon gases.

Ethylene glycol

The oxidative carbonylation of methanol to dimethyl oxalate provides a promising approach to the production of C 1 -based ethylene glycol. The relative sweetness of ethylene glycol [24] and propylene glycol [25] is discussed in the Merck Index, and neither compound is described as bitter.


Retrieved December 31, Polyethylene terephthalateused to make plastic bottles for soft drinksis prepared from ethylene glycol.

The glycol and water are separated, and the glycol recycled. Part of the Automobile series. Ethylene glycol is highly toxic. Because of its high boiling point and affinity for water, ethylene glycol is a useful desiccant. Ingestion of sufficient amounts is fatal if untreated.

So, while providing freeze protection and an increased boiling point, ethylene glycol lowers the specific heat capacity of water mixtures relative to pure water. Ethylene glycol is used as a protecting group for carbonyl groups in organic synthesis. Royal Society of Chemistry.

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 wthanediol below the freezing temperature of water.

Instead of removing water, ethylene glycol ethanedilo also be used to depress the temperature at which hydrates are formed. Therefore, only carbon monoxide, hydrogen, and oxygen are ethsnediol. See the article on propylene glycol for more information.

Archived from the original on etjanediol December Retrieved from ” https: Australia, the UK, and seventeen US states as of require ethaediol addition of a bitter flavoring denatonium benzoate to antifreeze.
