DME (Dimethyl Ether), also known as methyl ether and methoxymethane, is the simplest fatty ether. 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 ether 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:
Our DME production utilizes advanced methanol gas-phase catalytic dehydration technology, yielding fuel-grade dimethyl ether 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:
