Gas Phase Dehydration of Isoamylalcohol on Alumina Catalyst

Gas phase dehydration of isoamylalcohol on spherical alumina catalyst was studied by a packed bed reactor. The reaction was operated under the constant conditions of 350°and the atmospheric pressure. The main products were 3-methyl-1-butene, 2-methyl-1-butene, 2-methyl-2-butene and water, and we could neglect the other byproducts for our calculation. The reverse process of dehydration reaction might be neglected. By the analysis of our results (Fig 3, 4), this dehydration reaction was summarised as equations (7)-(12), and we determined the rate-constants from our results.
