The complex system of six reactions occurring when 1-butanol is dehydrated on alumina at 260 °C was investigated. Initial kinetics of 1-butanol, di-(1-butyl) ether and 1-butene transformations were analyzed and best fitting rate equations for all reactions were selected. The inhibiting effects of water on initial rates was quantitatively expressed. Very low conversion data provided additional evidence for the validity of the parallel-consecutive reaction network of alcohol dehydration. In all the alkene-forming reactions, 1-butene was the primary product which was then isomerized into a mixture of cis- and trans-2-butenes.
