Abstract

This paper presents the adsorption of o-xylene in zeolite AgZSM-5 at a temperature of 303 K. To measure the isotherms and differential heats of adsorption, we used a system consisting of a universal high-vacuum adsorption unit and a differential modified microcalorimeter of the Tiana-Calve DAK-1-1A type connected to it. The adsorption entropy of o-xylene was calculated from isotherms and differential heats of adsorption using the Gibbs-Helmholtz equation. It has been determined that, in general, the molar differential entropy of o-xylene adsorption is lower than the entropy of liquid o-xylene, which indicates a sharp limitation of the mobility of o-xylene molecules in the zeolite.
