DME (Dimethyl Ether) is an organic compound with the chemical formula C₂H₆O. As a colorless, flammable gas at room temperature, it serves as a homolog of methyl ether with excellent physical and chemical properties that make it valuable across multiple industrial applications.
DME exists as a colorless gas under standard conditions, with a boiling point of -24.9°C and melting point of -141.5°C. Its polar molecular structure provides low solubility in water but miscibility with most organic solvents. Chemically stable under normal conditions, DME undergoes clean combustion to produce CO₂ and water.
