"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.
