Dimethyl ether, diethyl ether & ethylene from alcohols over tungstophosphoric acid based mesoporous catalysts

Catalytic Ethanol Dehydration to Ethylene over Nanocrystalline χ- and γ-Al₂O₃ Catalysts

“…At low temperature, ethanol dehydration is predominantly a bimolecular reaction whilst the unimolecular reaction route prevails at high temperature 30 . On the contrary, the mechanism of ethylene formation has been expected from the decomposition of diethyl ether at higher temperature 31,32 .…”

Ethylene Formation by Catalytic Dehydration of Ethanol with Industrial Considerations

“…Ciftci et al (2012) also studied the modification of tungstophosphoric acid (TPA) by impregnating it into MCM-41 [31]. The resulting TPA-MCM-41 catalyst achieved 99.9% ethylene selectivity at 300 °C, with about 98% ethanol conversion.…”

Diethyl ether cracking and ethanol dehydration: Acid catalysis and reaction paths

“…Other authors believe that DEE can be formed by reaction of an adsorbed ethanol molecule with an ethoxide group [15] or of two ethoxide groups [16]. Several authors [12,[17][18][19][20][21][22] also suggest that diethyl ether might be an intermediate in the dehydration of ethanol to ethylene. The selective production of DEE can be of interest because it is in fact a considerable product of the chemical industry, mostly used as a solvent in a number of fine chemistry, fragrance and pharmaceutical chemical processes, and in some processes involved in explosives synthesis [23].…”
