DME (Dimethyl ), also known as methyl and methoxymethane, is the simplest fatty . It is derived from the dehydration condensation of two methanol molecules. At room temperature, it appears as a colorless, non-toxic gas or compressed liquid with a slight aroma. As an important organic chemical product and intermediate, DME serves multiple industrial purposes.

DME demonstrates excellent stability in air, is non-corrosive, slightly toxic, and non-carcinogenic. It exhibits good miscibility with most polar and non-polar organic solvents.

As a chemical intermediate, DME participates in various reactions:

• Alkylation with benzene (catalyzed)
• Reaction with carbon monoxide to produce methyl acetate
• Homologation reactions forming ethyl acetate and acetic anhydride
• Reaction with carbon dioxide yielding methoxyacetic acid
• Reaction with fuming sulfuric acid producing dimethyl sulfate
• Reaction with hydrogen cyanide forming acetonitrile

• Exhibits methylation reaction properties with various compounds
• Forms explosive mixtures when combined with air
• Stable under normal conditions
• Incompatible with: strong oxidizers, acids, halogens, sulfur compounds
• Avoid contact with air and light
• No polymerization hazard

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

Our DME production utilizes advanced methanol gas-phase catalytic dehydration technology, yielding fuel-grade dimethyl exceeding 99.0% concentration. Further purification through a lightness removal tower (employing high-efficiency corrugated rolled perforated plate filler) achieves refined (99.9%) and high-purity (99.99%) grades.

DME's chemical stability and low molecular weight enable high reactivity for energy and chemical processes. Combustion reaction:
