China and the United States are the leading exporters of dimethyl ether, together accounting for a majority of global shipments, while India, South Korea, and Germany represent the largest importers. Dimethyl ether prices have remained relatively stable amid steady demand from industrial fuel and aerosol propellant applications. Exports from China have expanded modestly over the past three years, while Indian imports have risen consistently, reflecting growing domestic use in clean cooking fuel programs.
Dimethyl ether (DME) is a colorless, highly volatile gas at ambient temperature with a mild, ethereal odor; it is typically handled as a liquefied gas under moderate pressure and has a boiling point of −24.8 °C and a melting point of −141.5 °C. It is classified as an aliphatic ether and a simple oxygenated hydrocarbon. DME serves primarily as an aerosol propellant, a clean-burning alternative fuel for diesel engines and cooking applications, and a chemical intermediate in the production of dimethyl sulfate and methyl halides. It is also used as a solvent and extraction medium in pharmaceutical and polymer processing, and as a feedstock in methanol-to-olefins (MTO) processes for light olefin synthesis.
Dimethyl ether is used as a solvent in aerosol formulations.
Dimethyl ether is a liquefied gas and exists as a liquid at room temperature when contained under its own vapor pressure, or as a gas when exposed to room temperature and pressure.It is a clear, colorless, virtually odorless liquid. In high concentrations, the gas has a faint ether-like odor.
