Dimethyl ether product description
Dimethyl ether (DME) is a colorless, non-toxic gas with a slight ethereal aroma that can be liquefied for storage. It is an important clean energy source and chemical raw material, known as a "green alternative to liquid fuel gas."
Due to its advantages such as complete combustion, clean emissions, and convenient storage and transportation, DME has been widely used in various fields, including energy, chemicals, refrigeration, and aerosol propellants.

Key Characteristics of Dimethyl Ether
Clean and Environmentally Friendly:
· Combustion products are primarily carbon dioxide and water, with no smoke, sulfur, or particulate matter emissions.
· Conforms to the trend of clean energy development and can significantly reduce air pollution.
Excellent Combustion Performance:
· Excellent ignition performance, high combustion efficiency, and no carbon deposits.
· Has a high cetane number (approximately 55-60) and superior combustion stability to diesel.
Easy to Liquefy and Store and Transport:
· Can be liquefied at room temperature with slight pressurization (approximately 0.5 MPa).
· Storage and transportation methods are similar to those of liquefied petroleum gas (LPG), allowing for shared storage and transportation facilities.
Wide Applications:
· Can be used as household gas, a diesel alternative fuel, a spray propellant, a refrigerant, and a chemical raw material.
· Is a key intermediate for a variety of high-end chemical products (such as dimethylamine, dimethylsulfuric acid, acetic acid, and polyoxymethylene).
Diverse Sources:
· Can be synthesized from a variety of feedstocks, including coal, natural gas, biomass, and methanol.
· Supports renewable energy routes (such as biomass-based dimethyl ether and biomethanol).
High Safety:
· Non-toxic and non-corrosive, with stable combustion and no significant environmental damage.
· Wide explosion range (3.4% to 27%), but easy to detect and control.
Immense Development Potential:
· An important new energy source that replaces traditional fossil fuels and promotes energy transition.
· Against the backdrop of achieving carbon peak and carbon neutrality, dimethyl ether is becoming a vital component of the green energy industry.
