Data for 2013 from a variety of sources including IHS Markit, 2016. Much of this ethylene glycol is used as antifreeze in automobile radiators. Ethylene glycol is an alcohol that is used as an antistatic agent in combination with other organic chemicals to make numerous formulations. 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 physical properties of ethylene glycol-water mixtures are therefore extremely important. Ethylene glycol is a chemical compound that has an alcohol with two -OH groups. … If the flow direction of one of the fluids is reversed. Safety is key when handling Ethylene Glycol. It is odorless liquid and has a sweet taste. Read More. 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. Acute (short-term) exposure of humans to ethylene glycol by ingesting large quantities causes three stages of health effects: central nervous system (CNS) depression, followed by cardiopulmonary effects, and later renal damage. Consult your pharmacist or physician. 4. Food Industry; Another testament to the non-toxic nature of PG is its use in the food industry where it serves as a humectant, solvent and preservative among other things. 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. 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. It is produced commercially from ethylene oxide, which is obtained from ethylene. If you work in an industry that uses or manufactures ethylene glycol you may also could be exposed by ethylene glycol … It is a colorless liquid which has a syrup-like consistency. Polyethylene Glycol: Polyethylene glycol has many uses including medical uses, chemical uses, biological uses, industrial uses, etc. Conclusion. In pure form, ethylene glycol is a clear liquid. Shengyu Shi. This reaction can be catalyzed by either acids or bases, or can occur at neutral pH under elevated temperatures. Indeed 45% of the polyester is used for bottles 1. Uses. The site uses state-of-the-art ethylene glycol process technology. Ethylene glycol (EG) is a common cause of toxic ingestions. 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). Mono Ethylene Glycol is used as a reactant in the manufacture of Alkyd resins which are used in paints, enamels, and varnishes. 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. Polyethylene glycol is produced by the interaction of ethylene oxide with water, ethylene glycol, or ethylene glycol oligomers. Conservation of fuel and energy essay and ethylene glycol properties essay and applications. To understand the purpose of glycol, you must first understand how a chiller works. Protective eye-wear, proper clothing, and gloves should be standard PPE when handling … This chemical also named as Ethane-1,2-diol or Monoethylene glycol. 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. Ethylene glycol is a colorless, odorless, sweet-tasting chemical. Ethylene Glycol: Ethylene glycol is mainly used for the manufacturing of polyester fibers and as an automotive antifreeze. Let us have a look at the ethene structure and formula. They are alcoholic compounds due to the presence of –OH groups. Ethylene Glycol can be used safely and effectively without injury. 3. Mono Ethylene Glycol (MEG) is an essential component used as raw material in diverse industrial processes such as the manufacture resins, polyester, fibers and various types of films. High‐Fidelity End‐Functionalization of Poly(ethylene glycol) Using Stable and Potent Carbamate Linkages. Glycol comes in two varieties: ethylene glycol and propylene glycol. The compound ethylene glycol is a clear, colorless, viscous liquid principally used as a component in automotive antifreeze or coolant products and also has manufacturing and industrial applications. This organic compound is highly toxic. 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. PEG has low toxicity with systemic absorption less than 0.5%. Ethylene is a hydrocarbon. Through a streamlined process design, this results in lower capital and energy cost and higher raw material efficiency. 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. It is poisonous if swallowed. However, it is not just to keep the radiator from freezing but… A daring feat of construction . Percentage of glycol used can be determined by a location’s lowest outdoor ambient temperature and also the temperature of the process application loop. The end uses for ethylene glycol are numerous. Gas chromatography (GC)-based laboratory assays are the gold standard for diagnosing EG intoxication. Ethylene glycol can enter your body when it is ingested, or when materials that contain it are ingested (antifreeze/coolant, inks, brake fluids, etc.) 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. 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. 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. Find Lowest Prices. Monoethylene glycol (MEG) is an important raw material for industrial applications. Its chemical formula is C 2 H 4 (OH) 2. Propylene glycol is used in antifreeze because, like ethylene glycol, it lowers the freezing point of water by disrupting the formation of ice crystals. It is a colorless syrupy liquid, toxic and has a sweet taste. Ethylene glycol is an antifreeze product used in industrial glycol cooling equipment. 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. It is also used in antifreeze applications and in pharmaceuticals and cosmetics. Side Effects. The widespread use of ethylene glycol as an antifreeze is based on its ability to lower the freezing point when mixed with water. Monoethylene glycol (MEG), also known as ethylene glycol (EG) or simply glycol, is a diol mostly used for the production of polyester fibers and polyethylene terephthalate (PET) resins. Ethylene glycol and propylene glycol based coolants and antifreeze have some fundamental differences that can determine the best product for the application. The main difference between propylene glycol and ethylene is the level of toxicity and efficiency of performance. 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. Ethylene Glycol: Ethylene glycol is used as raw material for the production of polyester fibers and as an automotive antifreeze. MEG is also used in antifreeze applications.
