Dimethyl Ether

March 16, 2026

The Council of Scientific and Industrial Research- National Chemical Laboratory (CSIR-NCL) in collaboration with a processing engineering partner is ready to scale up the Dimethyl Ether technology to an industrial scale demonstration.

About Dimethyl Ether:

  • It is a synthetically produced alternative to diesel for use in specially designed compression ignition diesel engines.
  • Properties of Dimethyl Ether 
    • It has a very high cetane number, which is a measure of the fuel’s ignitibility in compression ignition engines.
    • Under normal atmospheric conditions, DME is a colorless gas.
    • It burns cleaner, emitting minimal amounts of soot, nitrogen oxides (NOx), sulfur oxides (SOx), and particulate matter.
    • Furthermore, DME exhibits thermal efficiency that is comparable to traditional fuels, making it a viable substitute
    • It can be a viable alternative fuel and engine technology to adapt to conventional diesel engines used in India’s agricultural and transport sectors.
  • Application of Dimethyl Ether:
    • It is used extensively in the chemical industry and as an aerosol propellant.
    • It is used in chemical industries and also to produce dyes and plastics.
