It is a hydrocarbon and the simplest alkyne. Pure acetylene is odorless, but commercial grades usually have a marked odor due to impurities. The LibreTexts libraries are Powered by MindTouch® and are supported by the Department of Education Open Textbook Pilot Project, the UC Davis Office of the Provost, the UC Davis Library, the California State University Affordable Learning Solutions Program, and Merlot. It is also suitable for palladium-catalyzed reactions including Suzuki reactions and Stille couplings. Monoglyme is produced industrially by the reaction of dimethylether with ethylene oxide:[3][4]. D. Berndt, D. Spahrbier, "Batteries" in Ullmann’s Encyclopedia of Industrial Chemistry 2005, Wiley-VCH, Weinheim. It has a boiling point of −88.5 °C (−127.3 °F) and melting point of −182.8 °C (−297.0 °F). However, at low temperature and/or high pressures the gas becomes a liquid or a solid. Dimethoxyethane is also a good solvent for oligo- and polysaccharides. This colorless gas is widely used as a fuel and a chemical building block. ]; Colourless gas with garlic-like ordour. propylene carbonate), dimethoxyethane is used as the low-viscosity component of the solvent for electrolytes of lithium batteries. The curve between the critical point and the triple point shows the ethane boiling point with changes in pressure. Together with a high-permittivity solvent (e.g. Solid ethane exists in several modifications. It is a hydrocarbon and the simplest alkyne. Ethylene is separated from the resulting mixture by repeated compression and distillation. 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. It is a hydrocarbon and the simplest alkyne. Dimethoxyethane acts as a bidentate ligand for some metal cations. [Note: Commercial grade has a garlic-like odor. It also shows the saturation pressure with changes in … It is therefore often used in organometallic chemistry. It is unstable in its pure form and thus is usually handled as a solution. This colorless gas (lower hydrocarbons are generally gaseous in nature) 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. The ethane phase diagram shows the phase behavior with changes in temperature and pressure. Missed the LibreFest? The carbon–carbon triple bond places all four atoms in the same straight line, with CCH bond angles of 180°. Boiling point −103.7 °C (−154.7 °F; 169.5 K) Solubility in water. Acetylene (systematic name: ethyne) is the chemical compound with the formula C2H2. At standard temperature and pressure, ethane is a colorless, odorless gas. Legal. Melting point −58 °C (−72 °F; 215 K) Boiling point: 85 °C (185 °F; 358 K) Acetylene (systematic name: ethyne) is the chemical compound with the formula C2H2. Shipped under pressure dissolved in acetone. Dimethoxyethane is often used as a higher boiling alternative to diethyl ether and THF. Unless otherwise noted, LibreTexts content is licensed by CC BY-NC-SA 3.0. [2] Dimethoxyethane is miscible with water. 1,2-Dimethoxyethane - chemical product info: properties, production, applications. Add Spectra . Ethane is a gas at standard conditions. As an alkyne, acetylene is unsaturated because its two carbon atoms are bonded together in a triple bond. We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. Except where otherwise noted, data are given for materials in their. Acetylene (systematic name: ethyne) is the chemical compound with the formula C 2 H 2. When ethane is the feedstock, ethylene is the product. Grignard reactions and hydride reductions are typical application. On cooling under normal pressure, the first modification to appear is a … It is unstable in its pure form and thus is usually handled as a solution. Boiling point: -84; Solubility: Water, 1200 mg/L (20 deg C) Safety sheet: Not available; Spectra: ChemSpider (IR (1, 2)), also check on SDBS. In the laboratory, DME is used as a coordinating solvent. Have questions or comments? Appearance: Colorless gas with a faint, ethereal odor. 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: 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.
