Colorless, easily liquefied gas with a slightly bright flame when burning. Key physical properties:

• Boiling point: -24.9°C
• Melting point: -141.5°C
• Flash point (open cup): -41.4°C
• Relative density: 1.617 (air=1)
• Liquid density: 0.661g/cm³
• Critical pressure: 5.32MPa
• Critical temperature: 128.8°C

• Explosion limit (in air): 3.45%~26.7% (volume)
• Soluble in water, gasoline, carbon tetrachloride, benzene, chlorobenzene, and methyl acetate

• Environmentally Friendly: Combustion produces only CO₂ and H₂O, with no sulfur oxides or particulates
• High Purity: Suitable for sensitive applications like aerosol propellants
• Energy Efficient: High calorific value alternative to traditional fuels
• Easily Transportable: Storable as liquid under moderate pressure

• Clean energy with no soot emissions
• Versatile industrial, automotive, and domestic applications
• Cost-effective alternative to LPG and diesel
• Safe storage with minimal degradation risk
• Reliable supply from abundant methanol/natural gas resources

• Fuel:
  • LPG replacement for domestic/industrial cooking
  • Alternative diesel for automotive and power generation
• Aerosol Propellant: Cosmetics, pharmaceuticals, household sprays
• Chemical Feedstock: Synthesis of dimethyl sulfate, acetic acid
• Refrigerant: Efficient cooling agent replacement for Freon
• Welding/Cutting: Fuel for oxy-DME applications

Advanced methanol gas-phase catalytic dehydration produces fuel-grade DME (>99.0% concentration). Further separation yields refined (99.9%) and high-purity (99.99%) grades.

Combustion equation: CH₃OCH₃ + 3O₂ → 2CO₂ + 3H₂O + Energy
