Abstract
The possibility of determining the function characterizing the connectedness of pores of different types and sizes from the experimental adsorption isotherms is discussed. It is shown that the presence of joints of pores manifests itself by two indications in phase diagrams and adsorption isotherms that contain hysteresis loops. The first indication is related to the appearance of an additional phase transition in the phase diagram and/or a density jump in the isotherm. The second indication is related to different numbers of density jumps in the desorption and adsorption branches of adsorption isotherms. The character of the behavior of the adsorption branch of the isotherm in the case of the presence of regions of joints in a porous system is established.
