Product Description

Bulk Dimethyl Ether (DME) Compound Solvent LPG Substitute (CAS 115-10-6)

Main Uses of Dimethyl Ether (DME)

1. Replacement of Chlorofluorocarbons as Aerosols

With increasing global environmental awareness, DME serves as an eco-friendly alternative to chlorofluorocarbons previously used in aerosol applications.

2. Refrigerant and Foaming Agent Applications

DME's low boiling point, high heat of vaporization, and vaporization characteristics similar to chlorofluorocarbons make it ideal for:

Refrigerators and air conditioning systems
Food preservation applications
Foaming agent for polystyrene, polyurethane, and thermoplastic polyester foams

Foamed products using DME exhibit uniform pore size with enhanced flexibility, pressure resistance, and crack resistance.

3. Fuel Applications

DME's properties make it an excellent clean energy alternative:

Similar vapor pressure to LPG (liquefies under low pressure, gasifies at normal conditions)
High cetane number (~55) suitable for diesel engine applications
Low toxicity and excellent combustion characteristics
Applications in clean civilian fuels, automotive engine fuels, and alcohol fuels

Production Methods

Methanol Dehydration Method

Primary industrial production method using methanol dehydration reaction with catalysts (γ-alumina, ion exchange resins):

2CH₃OH → CH₃OCH₃ + H₂O

Advantages include simple process and low production costs.

Synthesis Gas Production Method

Utilizes syngas (CO + H₂ mixture) through:

One-step method: Direct DME synthesis from syngas

2CO + 4H₂ → CH₃OCH₃ + H₂O

Two-step method: Syngas to methanol conversion followed by dehydration

Benefits include wide raw material availability and high production efficiency.

Market Prospects

Growing global demand for clean energy and chemical raw materials positions DME for significant market expansion, particularly in China where government policies strongly support DME industry development. Continuous technological advancements and expanding applications promise enhanced economic and environmental benefits.

Conclusion

DME's unique properties enable diverse applications across fuel, refrigeration, foaming, and chemical industries. With methanol dehydration and syngas methods as primary production technologies, DME is poised to play an increasingly vital role in sustainable industrial development and environmental protection.
