Summary 1. The use of the NMR pulsed gradient method has permitted the selective measurement of the coefficients of intracrystalline self-diffusion (CSDs) of mixtures of substances sorbed by zeolites. 2. In a study of binary mixtures of n-heptane and benzene adsorbed by zeolite NaX, dependences of the CSD on the degree of filling that are typical for the sorption of individual substances have been obtained. With an increase in the total degree of filling, the CSD of n-heptane decreases monotonically, while the CSD of benzene remains constant up to medium values of the total degree of filling. 3. The differences in the dependences of the CSDs on the degree of filling for the two substances can be explained by the different natures of their interaction with the zeolite.
