WebDME can be produced by a gas phase condensation reaction of methanol using an acid catalyst. The reaction of Methanol to DME is as follows: 2 MeOH <-> DME + H 2 O It is an exothermic equilibrium reaction catalyzed by an acid. There are numerous options for the catalyst, but typically solid (heterogeneous) catalysts are suggested in the literature. WebTheoretically, as the dehydration of methanol to DME is an exothermic reaction, the DME production is favored at low temperature. The catalysts used to conduct this reaction are of solid-acid type. 2.2Direct synthesis method More recently, a direct synthesis method has been developed. This route allows the synthesis of DME directly from syngas:
