A chart showing production methods of dimethyl ether.

Dimethyl Ether (DME) is created by the dehydration of two methanol molecules methanol across an alumina catalyst.

2 CH3OH --> H2O + CH3OCH3

DME can be created in two steps with the creation of methanol across ZnO and CuO, then its dehydration to DME in the presence of Al2O3.

DME can also be synthesized in a single step which is typically a combination of both catalysts, ZnO/CuO and Al2O3. When the synthesis of methanol and methanol dehydration happen in the same step, an interesting third reaction interaction happens: the water-gas shift.
