Beschreibungen/Notizen

• When benzene is sorbed into activated carbon powder, two distinct fractions are found using longitudinal field muon spin relaxation measurements, and are characterized by activation energies of 6 and 26 kJ mol−1 in respect of molecular reorientation. This is due to location of benzene in large (meso and macro) pores and micropores, respectively; escape from the latter is accompanied by a large, positive activation entropy of +52 J mol−1 K−1.
