Kinetics of desolvation of inclusion compounds of 9,10-derivatives of trans-9,10-dihydroxy-9,10-dihydroanthracene with benzene

Abstract

The structures of the inclusion compounds of trans-9,10-dihydroxy-9,10-di-p-tert-butylphenyl-9,10-dihydroanthracene (DDTBDA) and trans-9,10-dihydroxy-9,10-di-α-naphthyl-9,10-dihydroanthracene (DDNDA) with benzene, with host : guest ratios of 1:3 and 1:1, respectively, have been elucidated. Their isothermal kinetics of desolvation have been studied. DDTBDA·3benzene desolvates in a single deceleratory step following the first-order kinetic model. The αvs. time curves for the desolvation of DDNDA·benzene are of truncated sigmoidal shape and are best described by the Prout-Tomkins model.
