It is odorless liquid and has a sweet taste. Antifreeze Ethylene Glycol (MEG) is used as an active ingredient in engine coolants and antifreeze, offering benefits including a high boiling point, low vapor pressure, excellent heat transfer abilities, and the ability to depress the freezing point of water. Much of this ethylene glycol is used as antifreeze in automobile radiators. Side Effects. Ethylene glycol and its oligomers are preferable as a starting material instead of water, because they allow the creation of polymers with a low polydispersity (narrow molecular weight distribution). If the flow direction of one of the fluids is reversed. DESCRIPTION: Ethylene glycol is a useful industrial compound found in many consumer products, including automotive antifreeze, hydraulic brake fluids, some stamp pad inks, ballpoint pens, solvents, paints, plastics, films, and cosmetics; it also is used as a pharmaceutical vehicle. Though both materials are bad for living things, propylene glycol is most often used near food and ethylene glycol is most often used in industrial applications. Read More. Water is used to cool ethylene glycol in a 10-m-long double pipe counterflow heat ex- changer made of 4-std and 2-std (both type M) copper tubing. Ethylene glycol (also called 1,2-ethanediol, molecular formula HOCH 2 CH 2 OH) is a colourless, oily liquid possessing a sweet taste and mild odour. In pure form, ethylene glycol is a clear liquid. Polyethylene Glycol: Polyethylene glycol has many uses including medical uses, chemical uses, biological uses, industrial uses, etc. The addition of ethylene glycol to water causes the freezing point of the latter to decrease, thus the damage that would be caused by the water freezing in a radiator can be avoided by using a mixture of water and ethylene glycol as the coolant. Gas chromatography (GC)-based laboratory assays are the gold standard for diagnosing EG intoxication. 4. Ethylene Glycol can be used safely and effectively without injury. This article is for information only. Ethylene Structure. This chemical also named as Ethane-1,2-diol or Monoethylene glycol. Solution for A mixture of ethylene glycol (C2H6O2) and water is used as an antifreeze in cars. Ethylene glycol (EG) is a common cause of toxic ingestions. Percentage of glycol used can be determined by a location’s lowest outdoor ambient temperature and also the temperature of the process application loop. Ethylene Glycol: Ethylene glycol is mainly used for the manufacturing of polyester fibers and as an automotive antifreeze. CAS Key Laboratory of Soft Matter Chemistry, Hefei National Laboratory for Physical Sciences at the Microscale, Department of Polymer Science and Engineering, University of Science and Technology of China, 96 Jinzhai Road, Hefei, Anhui Province, 230026 China . The world-class facility is also next to a cracker, which supplies the plant with ethylene. Ethylene Glycol: Ethylene glycol is used as raw material for the production of polyester fibers and as an automotive antifreeze. Basic Uses of Ethylene Glycol in Industrial Processes. It is a colorless syrupy liquid, toxic and has a sweet taste. The flow rate of the ethylene glycol is 10 kg/s, while that for the water is 15 kg/s. Most ethylene glycol poisonings occur due to the ingestion of antifreeze. MEG is also used in antifreeze applications. Conclusion. Conclusion. The physical properties of ethylene glycol-water mixtures are therefore extremely important. Ethylene Glycol (C2H6O2) - Ethylene glycol is the first member of the series of alkane diols and is also known as glycol. Further, ethylene is also used in agricultural practices to ripen fruits, germination of the seed, etc. The reaction is catalyzed by acidic or basic catalysts. Ethylene is abundantly used in the chemical industry, and the polyethene is extremely produced using ethylene. Uses. Ethylene glycol may be swallowed accidentally, or it may be taken deliberately in a suicide attempt or as a substitute for drinking alcohol (ethanol). Ethylene glycol is an antifreeze product used in industrial glycol cooling equipment. Polyethylene glycol, referred to as PEG, is used as an inactive ingredient in the pharmaceutical industry as a solvent, plasticizer, surfactant, ointments, and suppository base, and tablet and capsule lubricant. Using a hierarchy of controls protects employees from exposure and injury due to the chemical. MEG is conventionally produced through the hydrolysis of ethylene oxide (EO), which itself is obtained via ethylene oxidation. Propylene Glycol: Propylene Glycol is used as a solvent for intravenous, oral, and topical pharmaceutical preparations. Propylene glycol has the E-Number E1520. It can also pass through the skin. The water inlet temperature is 15 C and the ethylene glycol inlet temperature is 80 C . The widespread use of ethylene glycol as an antifreeze is based on its ability to lower the freezing point when mixed with water. Mono Ethylene Glycol is used as a reactant in the manufacture of Alkyd resins which are used in paints, enamels, and varnishes. TCC’s Ethylene Glycol’s major end uses are as an antifreeze, which accounts for more than 50% of ethylene glycol’s commercial use, and as raw material in the production of polyester fibers and plastics, mainly PET, which accounts for 40% of total ethylene glycol consumption. How to use Ethylene Glycol Liquid. Its chemical formula is C 2 H 4 (OH) 2. Most monoethylene glycol (MEG) is used to make polyester fibres for textile applications, PET resins for bottles and polyester film. If you work in an industry that uses or manufactures ethylene glycol you may also could be exposed by ethylene glycol … Because this material is cheaply available it finds many niche applications. Protective eye-wear, proper clothing, and gloves should be standard PPE when handling … It is produced commercially from ethylene oxide, which is obtained from ethylene. Ethylene glycol is an alcohol that is used as an antistatic agent in combination with other organic chemicals to make numerous formulations. Ethylene glycol can enter your body when it is ingested, or when materials that contain it are ingested (antifreeze/coolant, inks, brake fluids, etc.) It is primarily used as a raw material to produce polyester fibers for the fabric industry, and polyethylene terephthalate resins (PET) used in the bottle industry. Side Effects. Construction of the 110 acre site took under two years. Ethylene glycol is produced from ethylene, via the intermediate ethylene oxide Ethylene oxide reacts with water to produce ethylene glycol according to the chemical equation C 2 H 4 O + H 2 O → HOCH 2 CH 2 OH. The site uses state-of-the-art ethylene glycol process technology. Consult your pharmacist or physician. Ethylene glycol and propylene glycol based coolants and antifreeze have some fundamental differences that can determine the best product for the application. This organic compound is highly toxic. Ethylene is a hydrocarbon. Ethylene glycol is a colorless, odorless, sweet-tasting chemical. However, it is not just to keep the radiator from freezing but… Propylene glycol is used in antifreeze because, like ethylene glycol, it lowers the freezing point of water by disrupting the formation of ice crystals. Indeed 45% of the polyester is used for bottles 1. • The use of MEGlobal Ethylene Glycol Products (MEG, DEG) as a component of heat transfer fluids in systems where the heat transfer fluids could infiltrate (i.e., via an exchanger leak, backflow prevention failure, or other means) a potable water system is not supported by MEGlobal. MEG is primarily used as raw material in different forms for carrying out a number of industrial processes including: Coolant & Heat Transfer Agent– Majorly ethylene glycol acts as a medium for convective heat transfer like in automobiles & liquid cooled computers. A daring feat of construction . A rat study comparing some aspects of ethylene glycol and diethylene glycol toxicity showed that blood and kidney oxalate concentrations were higher when ethylene glycol was given [59]. By far the most important uses of the diol is in the manufacture of polyesters, particularly PET (polyehylene terephthalate), used widely for clothes and for packaging. Ethylene glycol, which is derived from ethylene oxide, is used to manufacture fiberglass used in products ranging from jet skis to bathtubs to bowling balls, as well as polyethylene terephthalate (PET) plastic resin to make beverage containers and packaging film. Which are used in the manufacture of Alkyd resins which are used in industrial cooling applications freeze.
