Component in civilian composite ethanol and Freon aerosol substitutes
Applications in hair care, skincare, medicine, and coating products
Fuel additive with growing international adoption
Specialized uses in pharmaceutical, dye, and pesticide industries

Safety Information

Concentrations below 7.5mg/L may cause mild discomfort
Anesthesia can occur after 23 minutes of exposure
Loss of consciousness possible after 26 minutes (mouse studies show ~12% concentration threshold)
Skin contact may cause dermatitis
Operators must wear masks and rubber gloves
Highly flammable and explosive - requires strict fire source avoidance

Production Methods of DME

Methanol Dehydration Method

One of the primary production methods using methanol dehydration reaction with catalysts (γ-alumina, ion exchange resins). Reaction equation: 2CH₃OH → CH₃OCH₃ + H₂O. Features simple process and low cost, making it the mainstream industrial production technology.

Synthesis Gas Production Method

Uses synthesis gas (CO and H₂ mixture) as raw material through one-step or two-step processes:

One-step method: Direct DME production from synthesis gas (2CO + 4H₂ → CH₃OCH₃ + H₂O)
Two-stage method: Conversion to methanol first, then dehydration to DME

Advantages include wide raw material availability and high production efficiency.

Market Prospects

With growing global energy demand and environmental awareness, DME as a clean energy source and chemical raw material shows rapid market growth. Particularly in China with strong government support, DME demonstrates significant future potential. Continuous technological improvements and expanding applications will further enhance its economic and social benefits.

Conclusion

DME's unique properties enable diverse applications in fuel, refrigeration, foaming, and chemical production. With methanol dehydration and synthesis gas methods as primary production routes, DME holds promising market prospects. Future technological advancements and application expansions will likely increase DME's industrial importance, contributing to sustainable economic and environmental development.
