Boiling Point:-88.8±3.0 °C at 760 mmHg Vapour Pressure: 28534.0±0.1 mmHg at 25°C Enthalpy of Vaporization: 16.8±0.8 kJ/mol Flash Point:-129.5±6.6 °C Index of Refraction: Together with a high-permittivity solvent (e.g. https://en.wikipedia.org/w/index.php?title=Dimethoxyethane&oldid=966341838, Pages using collapsible list with both background and text-align in titlestyle, Articles containing unverified chemical infoboxes, Creative Commons Attribution-ShareAlike License, This page was last edited on 6 July 2020, at 15:14. From Wikipedia. On cooling under normal pressure, the first modification to appear is a … However, at low temperature and/or high pressures the gas becomes a liquid or a solid. Ethylene is separated from the resulting mixture by repeated compression and distillation. 1,2-Dimethoxyethane - chemical product info: properties, production, applications. Acetylene (systematic name: ethyne) is the chemical compound with the formula C 2 H 2. Ethane is a gas at standard conditions. Missed the LibreFest? At standard temperature and pressure, ethane is a colorless, odorless gas. Have questions or comments? Acetylene (systematic name: ethyne) is the chemical compound with the formula C2H2. [Note: Commercial grade has a garlic-like odor. As an alkyne, acetylene is unsaturated because its two carbon atoms are bonded together in a triple bond. It is a hydrocarbon and the simplest alkyne. It is also suitable for palladium-catalyzed reactions including Suzuki reactions and Stille couplings. In the laboratory, DME is used as a coordinating solvent. Melting point −58 °C (−72 °F; 215 K) Boiling point: 85 °C (185 °F; 358 K) Add Spectra . It is unstable in its pure form and thus is usually handled as a solution. For more information contact us at info@libretexts.org or check out our status page at https://status.libretexts.org. [2] Dimethoxyethane is miscible with water. Dimethoxyethane is often used as a higher boiling alternative to diethyl ether and THF. Acetylene (systematic name: ethyne) is the chemical compound with the formula C2H2. It is unstable in its pure form and thus is usually handled as a solution. Dimethoxyethane is also a good solvent for oligo- and polysaccharides. propylene carbonate), dimethoxyethane is used as the low-viscosity component of the solvent for electrolytes of lithium batteries. Dimethoxyethane, also known as glyme, monoglyme, dimethyl glycol, ethylene glycol dimethyl ether, dimethyl cellosolve, and DME, is a colorless, aprotic, and liquid ether that is used as a solvent, especially in batteries. We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. Grignard reactions and hydride reductions are typical application. Watch the recordings here on Youtube! It is a hydrocarbon and the simplest alkyne. It is therefore often used in organometallic chemistry. Legal. Boiling point −103.7 °C (−154.7 °F; 169.5 K) Solubility in water. D. Berndt, D. Spahrbier, "Batteries" in Ullmann’s Encyclopedia of Industrial Chemistry 2005, Wiley-VCH, Weinheim. The curve between the critical point and the triple point shows the ethane boiling point with changes in pressure. Unless otherwise noted, LibreTexts content is licensed by CC BY-NC-SA 3.0. It has a boiling point of −88.5 °C (−127.3 °F) and melting point of −182.8 °C (−297.0 °F). Solid ethane exists in several modifications. The carbon–carbon triple bond places all four atoms in the same straight line, with CCH bond angles of 180°. Pure acetylene is odorless, but commercial grades usually have a marked odor due to impurities. ]; Colourless gas with garlic-like ordour. This colorless gas is widely used as a fuel and a chemical building block. This colorless gas is widely used as a fuel and a chemical building block.
