The vapor phase dehydration of ethanol to diethyl ether, as catalyzed by ion exchange resin, has been studied experimentally and theoretically for the transient state period following a step increase in flow rate. A mathematical model is developed to account quantitatively for the effects of adsorption and surface reaction on the product distribution in the effluent of a tubular reactor. The solution of the model is in good agreement with the experimentally observed behavior.
