Product Description
High Purity DME Dimethyl Oxybismethane Gas Aerosol Propellant Low Sulfur ODM
Introduction to Oxybismethane
Oxybismethane (DME) is an organic compound with chemical formula C₂H₆O. As a homologue of methyl , this colorless, flammable gas offers excellent physical and chemical properties with wide industrial applications.
Physical and Chemical Properties
Oxybismethane appears as a colorless gas with a distinct aroma at room temperature (boiling point: -24.9°C, melting point: -141.5°C). With polar molecular structure and low solubility, it mixes well with organic solvents while maintaining chemical stability against acids and alkalis. At high temperatures or with catalysts, it undergoes combustion to produce carbon dioxide and water.
