This product may not be used in the applications or end markets listed below. [24] The major danger is due to its sweet taste, which can attract children and animals. Water was removed by azeotropic distillation to shift the equilibrium to the right. Our products are typically delivered 1-3 (You will help other colleagues find this blog).

Ethylene Glycol Water Mixture Density Table Jazmin Miclette October 17, 2017 Uncategorized Leave a comment 642 Views Ethylene glycol heat transfer fluid ethylene density and specific weight density of ethanol water mixtures viscosity of automotive antifreeze
Density vs Specific Weight vs Specific Gravity I would like to point out that there are conceptual differences between density, specific weight and specific gravity.
[31] While prolonged low doses of ethylene glycol show no toxicity, at near lethal doses (≥ 1000 mg/kg per day) ethylene glycol acts as a teratogen. Ingestion of sufficient amounts is fatal if untreated. Skip to the beginning of the images gallery, No Country of Origin information available. See the article on. business days after order processing. The measurements have been performed in the temperature range from ‐−20°C to 180°C for thermal conductivity, from ‐−10°C to 150°C for density, and from – 10°C to 100°C for viscosity. EC Number 239-122-6. Ethylene glycol (IUPAC name: ethane-1,2-diol) is an organic compound with the formula (CH 2 OH) 2.It is mainly used for two purposes, as a raw material in the manufacture of polyester fibers and for antifreeze formulations.

Give us feedback about your experience on this site, 1.115 @ 20 °C (68 °F) Reference substance: (water = 1), 19.83 - 21 mPa.s @ 20 - 25 °C (68 - 77 °F). Op die manier wordt de carbonylgroep chemisch beschermd. [22] In this example, isophorone was protected using ethylene glycol with p-toluenesulfonic acid in moderate yield. It and its toxic byproducts first affect the central nervous system, then the heart, and finally the kidneys. ChemCentral offers Monoethylene/Ethylene Glycol in a variety of sizes in stock and ready to ship. [33], Except where otherwise noted, data are given for materials in their, Pure propylene glycol does not taste bitter, and pure propylene glycol is often used as a food additive, for instance in cake icing and shelf-stable whipped cream. Ethylene glycol is 17.93M. 12th ed. 55 gallon drum of Ethylene/Monoethylene Glycol (99%). Ethylene glycol is a diol, an alcohol with a molecular structure that contains two hydroxyl (OH) groups, and terephthalic acid is a dicarboxylic aromatic acid, an acid with a molecular structure that contains a large, six-sided carbon (or aromatic) ring and two carboxyl (CO2H) groups. Et2O) gives the corresponding a 1,3-dioxolane, which is resistant to bases and other nucleophiles. The 1,3-dioxolane protecting group can thereafter be removed by further acid hydrolysis. It enters the environment through the dispersal of ethylene glycol-containing products, especially at airports, where it is used in deicing agents for runways and airplanes. [26], Antifreeze products for automotive use containing propylene glycol in place of ethylene glycol are available.
It is an odorless, colorless, sweet-tasting, viscous liquid.
[29], Australia, the UK, and seventeen US states (as of 2012) require the addition of a bitter flavoring (denatonium benzoate) to antifreeze. Follow the link if you want to learn more about these differences. [30], Ethylene glycol is a high-production-volume chemical; it breaks down in air in about 10 days and in water or soil in a few weeks. How about an incentive to share this post? If the product is less than 100% pure,correct for the purity.
"[32] This molecule has been observed in outer space. Not found any post match with your request, STEP 2: Click the link on your social network, Can not copy the codes / texts, please press [CTRL]+[C] (or CMD+C with Mac) to copy. Thermal conductivity, density, and viscosity of ethylene glycol – water mixtures have been measured. Gelson Luz is a Mechanical Engineer, expert in welding and passionate about materials. EG has excellent electrical properties as a conductor and is suitable for freeze point depression.
They are generally considered safer to use, as propylene glycol isn't as palatable[note 1] and is converted in the body to lactic acid, a normal product of metabolism and exercise.
Ethylene glycol, also called ethane-1,2-diol, the simplest member of the glycol family of organic compounds.
MDL number MFCD00078666. Kroonethers, zoals 18-kroon-6, zijn vaak cyclische penta- en hexameren van 1,2-ethaandiol. [25] Several deaths are recorded annually in the U.S.
JavaScript seems to be disabled in your browser. A glycol is an alcohol with two hydroxyl groups on adjacent carbon atoms (a 1,2-diol). Upon ingestion, ethylene glycol is oxidized to glycolic acid, which is, in turn, oxidized to oxalic acid, which is toxic. Linear Formula DOCD 2 CD 2 OD . Ethylene Glycol. "Based on a rather extensive database, it induces skeletal variations and malformations in rats and mice by all routes of exposure. This is calculated using the density (1.113 g/ml) and the molecular weight (62.07 g/mol). In December 2012, US antifreeze manufacturers agreed voluntarily to add a bitter flavoring to all antifreeze that is sold in the consumer market of the US. Glycol is een grondstof voor zwavelmosterdgas, een verboden gifgas. PubChem Substance ID … alone. For the best experience on our site, be sure to turn on Javascript in your browser. The common name ethylene glycol literally means “the glycol derived from ethylene.” Search for "Gelson Luz" in your favorite browser to learn more. Molecular Weight 68.10 . [23], Ethylene glycol is moderately toxic, with an oral LDLo = 786 mg/kg for humans. Industrial-grade propylene glycol usually has a slightly bitter or acrid taste due to impurities. Ethylene glycol-d 6 98 atom % D CAS Number 15054-86-1.
