CH3OCH3 Dimethyl Ether DME Gas For LPG Blending Clean Combustion & Cost Effective

Introduction to DME

DME is an organic compound with a chemical formula of C2H6O. It is a homologue of methyl ethre and has the characteristics of being colorless, flammable and gaseous. Due to its excellent physical and chemical properties, dimethyl ethre has a wide range of application prospects in modern industry. This article will discuss in detail the uses, properties and production methods of dimethyl ethre.

Physical and chemical properties of DME

DME is a colorless gas at room temperature and pressure. Its boiling point is -24.9℃, melting point is -141.5℃, and density is 1.59 kg/m³. DME has a polar molecular structure and low solubility, but it is miscible with most organic solvents. Its chemical properties are relatively stable and it is not easy to react with acids and alkalis, but it can undergo combustion and oxidation reactions at high temperatures or in the presence of catalysts to produce carbon dioxide and water.
