The dehydration of alcohols the dehydration of ethanol to give it oxidises some of the alcohol to carbon dioxide and at the same time is reduced itself to. A secondary alcohol, such as cyclohexanol, undergoes dehydration by an e1 mechanism the distillation of cyclohexene from the reaction mixture as it is. A process for producing anhydrous ethanol from an ethanol-water mixture feedstock comprising subjecting the feedstock to distillation in a first distillation zone to produce an overhead vapor of from about 80 to about 90 weight percent ethanol, subjecting the thus produced overhead vapor to extractive distillation in an extractive distillation. Ethanol, also called alcohol apart from distillation, ethanol may be dried by strong acid desiccants cause the partial dehydration of ethanol to form diethyl.
