Surface tension of dimethyl ether - NASA/ADS
WebDensity and surface tension for binary mixtures of diethylene glycol dimethyl ether, triethylene glycol dimethyl ether, and tetraethylene glycol dimethyl ether with water are … Dimethyl ether is a low-temperature solvent and extraction agent, applicable to specialised laboratory procedures. Its usefulness is limited by its low boiling point (−23 °C (−9 °F)), but the same property facilitates its removal from reaction mixtures. See more Dimethyl ether (DME; also known as methoxymethane) is the organic compound with the formula CH3OCH3, (sometimes ambiguously simplified to C2H6O as it is an isomer of ethanol). The simplest See more The largest use of dimethyl ether is as the feedstock for the production of the methylating agent, dimethyl sulfate, which entails its reaction with sulfur trioxide: CH 3OCH 3 + SO 3 → (CH 3) 2SO 4 Dimethyl ether can also be converted into acetic acid See more Unlike other alkyl ethers, dimethyl ether resists autoxidation . Dimethyl ether is also relatively non-toxic, although it is highly flammable. BASF Explosion Disaster on July 28, 1948 in See more • Methanol economy See more Approximately 50,000 tons were produced in 1985 in Western Europe by dehydration of methanol: 2 CH3OH → (CH3)2O + H2O The required methanol is obtained from synthesis gas (syngas).
