Aerosol Propellants Dimetil Eter DME Dimethyl Ether Gas Methoxymethane

Dimethyl ether (DME) is an organic compound with a chemical formula of C₂H₆O. This colorless, flammable gas exhibits excellent physical and chemical properties, making it valuable for diverse industrial applications.

Methoxymethane is a colorless gas with a slight ether aroma at standard conditions. With a boiling point of -24.9°C and melting point of -141.5°C, it exhibits polar molecular structure and low solubility while being miscible with most organic solvents. Chemically stable under normal conditions, it undergoes combustion and oxidation reactions at high temperatures or with catalysts.

• Chemical Raw Material: Primary methylating agent for dimethyl sulfate production and synthesis of various chemical compounds.
• Industrial Uses: Functions as alkylating agent, refrigerant, foaming agent, solvent, and extractant across multiple industries.
• Aerosol Propellant: Effective propellant for personal care, pharmaceutical, and coating applications.
• Fuel Additive: Clean-burning alternative fuel with environmental advantages over traditional petroleum products.

Methanol Dehydration: Catalytic dehydration of methanol (2CH₃OH → CH₃OCH₃ + H₂O) using γ-alumina or ion exchange resins - the predominant industrial method.

Synthesis Gas Method: Direct conversion of syngas (2CO + 4H₂ → CH₃OCH₃ + H₂O) or two-stage process via methanol intermediate, offering raw material flexibility.

Growing global energy demands and environmental regulations are driving DME market expansion, particularly in China where government support accelerates adoption. Continuous technological improvements and application discoveries enhance its economic viability.

DME's unique properties ensure diverse applications from chemical manufacturing to clean energy solutions. With advancing production technologies and expanding utilization, DME is positioned to significantly contribute to sustainable industrial development.
