Abstract

In a previous paper we proposed an experiment for detecting the inclusion of an azo-dye with a-cyclodextrin and measuring the equilibrium constant of the formation of the corresponding inclusion complex. In this article we study the kinetics of the formation of that inclusion complex of the guest molecule, mordant yellow 7 (MY7), 3-methyl-5-(4-sulfophenylazo)salicylic acid, in the host molecule, a-cyclodextrin.
