Dimethyl Ether CAS 115-10-6 | High-Purity Aerosol Propellant & Clean Fuel
Dimethyl Ether (DME, CAS 115-10-6) is a colorless, easily liquefied gas with a slight ethereal odor. Recognized as an environmentally superior chemical, DME features ultra-low global warming potential (GWP) and zero ozone depletion potential (ODP).
- Clean Combustion & Eco-Friendly Fuel Profile:Burning DME produces no particulate matter (PM), soot, or sulfur oxides (SOx). With a high cetane number (55-60), DME offers high combustion efficiency as an alternative to diesel and a blendstock for LPG.
- High Energy Density: DME offers higher energy density than traditional LPG, providing more efficient combustion and performance.
- Low-Temperature Liquefaction: DME can be easily liquefied at relatively low temperatures, making it convenient for storage and transportation.
Dimethyl ether Description
Name: Dimethyl ether (DME)
Synonyms: methoxymethane / Methyl ether / Oxydimethane / Wood ether / Dimethyl oxide / Methyl oxide / Dymel A
Molecular Formula: CH3OCH3
Molecular Weight: 46.07
CAS NO.: 115-10-6
Density: 0.7±0.1 g/cm3

Flashing point: -85.9±5.7 °C
Appearance: Colorless gas with ethers characteristic odor.
Water Solubility: Soluble in water, ethanol, ether.
Properties: Colorless, easily liquefied gas, with a slightly bright flame when burning. Soluble in water, gasoline, carbon tetrachloride, benzene, chlorobenzene, acetone and methyl acetate, DME is a low-temperature solvent and extraction agent.
Storage: For the safe storage of flammable gases, adhere to these critical guidelines: Maintain a cool, well-ventilated environment, far removed from ignition sources and heat. Ensure reservoir temperatures remain below 30°C. Isolate from incompatible materials like oxidants, acids, and halogens. Employ explosion-proof lighting and ventilation. Utilize non-sparking tools and equipment. Equip the storage area with comprehensive spill response materials.
Safety Protection: The anesthetic effect is weaker than ether. Contact with skin may cause dermatitis. Operators should wear masks and rubber gloves.
