Jostle Effect of Salts Dispersing into Zeolite Internal Pores

A salt can jostle into zeolite internal pores by heating the mixture of the salt and a zeolite even though the salt ion is a little larger than the zeolite channel. For example, Cl^-（3.6Å） can disperse into 3A zeolite pores and I^-（4.4Å） can go into 3A and 4A zeolite pores. This may be explained by nonrigility of atoms of salts and zeolite channels. However, C₆H₄（CO₂H） CO₂^-（7.9Å） couldn’t disperse into 3A, 4A and 5A zeolite internal pores because it is greatly larger than the channels of 3A, 4A and 5A zeolites, but it could disperse into 13X zeolite pores（8-9Å）.
