Dehydration of butanols on refractory carbides


The dehydration of 1-butanol and 2-butanol was studied in a microcatalytic reactor over refractory carbides (except Hf and Cr) in a temperature range between 40 and 500°C. The activity was comparable with that of oxides and salts. Varying the pulse size, the surface coverage — and the amount of reaction products—was found to be in good correlation with aLangmuir adsorption isotherm. Heats of adsorption and activation energies were calculated from experiments at different temperatures, the activation energies, using two different methods with good agreement. The activity of the refractory carbides increased in the periodic table of the elements from the left to the right and from bottom to top, as observed with salt-catalysts.
