The dehydration reaction of an alcohol catalyzed by acids is a reversible unimolecular elimination reaction following Saytzev's rule. As a dehydrating agent, any strong acid (sulfuric acid, phosphoric acid, or oxalic acid) can be used. ...
WebThe dehydration of cyclohexanol will give cyclohexane as product. The balanced reaction of the same is as follows: C6H13OH + H+ = C6H12 + H2O No …. Dehydration of an Alcohol Dehydration of an Alcohol The dehydration of an alcohol is the loss of water from the alcohol, resulting in an alkene. Alcohols do not easily undergo base-catalyzed ... WebCyclohexanol is dehydrated to cyclohexene by heating it in the presence of a heteropolyacid catalyst. The heteropolyacid is selected from tungstophosphoric acid, tungstosilicic acid, molybdophosphoric acid and molybdosilicic acid. Tungstophosphoric acid can be improved in its catalytic performance by calcination. The dehydration reaction is …
