Dimethyl ether and ethanol
WebDiethyl ether is produced from ethanol by this method. Cyclic ethers are readily generated by this approach. Elimination reactions compete with dehydration of the alcohol: R–CH 2 –CH 2 (OH) → R–CH=CH 2 + H 2 O The dehydration route often requires conditions incompatible with delicate molecules. Several milder methods exist to produce ethers. WebDME has been used as an ignition improver additive for methanol fuelled compression-ignition engines. DME is the lightest ether with a boiling point of only -25°C. It is a gaseous fuel at normal temperature and pressure, however, a mild pressure of approximately 6 bar is sufficient to keep it in liquid form.
