Aerosol Propellant
Dimethyl ether is a common propellant in aerosol formulations due to its low boiling point and non-corrosive nature. It is a favoured alternative to chlorofluorocarbons (CFCs) in various consumer and industrial spray products.
Chemical Synthesis
As a key methylating agent, dimethyl ether is utilised in various organic synthesis pathways. It is instrumental in the production of other chemicals and intermediates.
Refrigerant
Its thermodynamic properties allow dimethyl ether to be used as a refrigerant in specific cooling applications. It offers an alternative to traditional refrigerants in certain industrial settings.
Fuel Additive
Dimethyl ether has been explored as a potential clean-burning fuel and fuel additive, offering reduced particulate emissions compared to traditional diesel fuels.
