Last week, we took a look at the properties behind this highly toxic compound.This week, we’re talking about its many uses that stretch across a variety of different industries. This chemistry permits ethylene glycol to act as an intermediate in a wide range of reactions. Ethylene glycol is highly toxic to humans and is not used in food products. TCC’s Ethylene Glycol (MEG) is a toxic, colorless, practically odorless, low-volatility, low-viscosity, hygroscopic liquid. Ethylene glycol, a sweet-tasting, odorless liquid, is the active ingredient in antifreeze. The hydroxyl groups on glycols undergo the usual alcohol chemistry, giving a wide variety of possible derivatives. It is miscible in water, alcohol, ether, acetone, and ethylene glycol. The most common use of ethylene glycol is in antifreeze formulations. It is slightly viscous in nature and shows miscibility with alcohols, water, and aldehydes. Ethylene glycol is not presently a concern for the environment or human health at current levels of exposure. Origin. Like ethanol, ethylene glycol is rapidly absorbed in the GI tract, with peak absorption in 30-60 minutes. Both ethylene glycol and diethylene glycol are produced from same starting material; ethylene. Most ethylene glycol poisonings occur due to the ingestion of antifreeze. Ethylene glycol can facilitate convective heat transfer in automobiles and liquid cooled computers. Ethylene glycol (EG) is the organic compound commonly used in antifreeze. Immediate steps should be taken to limit its spread to the environment. Since it is a liquid it can easily penetrate the soil and contaminate groundwater and nearby streams. It is used to make polyester and to make antifreeze. References This page was last changed on 24 May 2020, at 17:52. Any petrochemical industry, tries to maximize the production of Diethylene Glycol and ethylene glycol because of their variety of applications in the oil and gas industry. Polyethylene glycol 3350 may also be used for purposes not listed in this medication guide. Ethylene glycol is rapidly absorbed from the gastrointestinal tract and slowly absorbed through the skin or lungs. DEG is a widely used solvent. Reference: 1. Ethylene glycol is rapidly absorbed from the gastrointestinal tract and slowly absorbed through the skin or lungs. Ethylene Glycol based water solutions are common in heat-transfer applications where the temperature in the heat transfer fluid can be below 32 o F (0 o C).Ethylene glycol is also commonly used in heating applications that temporarily may not be operated (cold) in surroundings with freezing conditions - such as cars and machines with water cooled engines. List of boiling and freezing information of solvents Solvent Boiling point (°C) Kf (°C/mol/kg) Ethylene glycol 197.3 –3.11 Formic acid 101.0 –2.77 Naphthalene 217.9 … The difference between ethylene glycol and diethylene glycol is that an ethylene glycol molecule is an individual molecule whereas diethylene glycol molecule is formed by the combination of two ethylene glycol molecules via an ether bond. Diethylene glycol (DEG) is an organic compound with the formula (HOCH 2 CH 2) 2 O. It and its toxic byproducts first affect the central nervous system (CNS), then the heart, and finally the kidneys. It is used in a wide variety of industrial applications, including as a compound in the manufacture of polyurethane plastic, in natural gas production, and as a solvent. Ethylene glycol and propylene glycol differ when considering physical, environmental, and heat transfer characteristics. Ethylene glycol can also be found, in lower concentrations, in some windshield de-icing agents, hydraulic brake fluid, motor oils, solvents, paints, film processing solutions, wood stains, inks, printer cartridges, etc. EG is also found in solvents, some resins, and low-freezing dynamites. There are a number of benefits using ethylene glycol over propylene glycol, especially in closed loop systems were risk of contact with food is minimal. Apart from this, it also plays a crucial role in the production of coolants, antifreeze and solvents. Ethylene glycol (EG) is the organic compound commonly used in antifreeze. However studies have shown that metabolism to significant amounts of ethylene glycol does not occur, and that the type of renal toxicity seen with DEG is different than what is seen with ethylene glycol.
