The dehydration of 2-methyl 1-butanol (2M1BOH) in the liquid phase was studied by using an ion-exchange resin, Amberlyst 15 in the H+ form. Experiments were carried out in a batch reactor with the dry resin as a catalyst. Considering the inhibition effect of water, the rate expressions based on the Langmuir-Hinshelwood model were formulated. The sorption equilibrium model between liquid and resin phases during resin swelling was included in kinetic modelling. The cross-linked ion-exchange resin was highly selective to water at the beginning of the reaction. The experimental results agreed well with the calculated ones.
