Dimethyl ether, also known as methoxymethane, oxybismethane, methyl ether, wood ether, and DME, is a colorless gaseous ether with an ethereal odor. Dimethyl ether gas is water soluble. It has the formula CH3OCH3. Dimethyl ether is used as an aerosol spray propellant. And used in conjunction with propane to create a chemical reaction in which cryogenic freezing is used for the removal of common warts found on the human body. Dimethyl ether is also a clean-burning alternative to liquified petroleum gas, liquified natural gas, diesel and gasoline. It can be made from natural gas, coal, or biomass.
