Dimethyl ether vapor density
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 ether, it is a colorless gas … 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.
