摘要：

The theoretical and experimental steps necessary for the rigorous usage of the isomerization of n-butenes as a test reaction to measure the surface acidity of microporous solid catalysts have been developed. The experimental study has been carried out with six catalysts of silica-alumina prepared at different levels of acidity strength. Between 155 and 200 °C and from the kinetic data obtained in the integral reactor, the kinetic constants of the reactions 1-butene to cis-butene, 1-butene to transbutene, and cis-butene to transbutene have been calculated. The calculated values have been compared with the values of the surface acidity measured following two conventional methods, the titration with n-butylamine in the liquid phase using Hammet indicators and the adsorption of tert-butylamine at a programmed temperature. © 1990, American Chemical Society.
