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.
