摘要
A new approach which allows the solvation surroundings of macrocyclic molecules to be simulated is proposed on the basis of thermogravimetric data. For the first time the compositions are determined of saturated solvates of tetraphenylporphin (H2TPP) with benzene, pyridine and carbon tetrachloride: H2TPP· 16C6H6, H2TPP· 18C5H5N and H2TPP·16CCl4. The energetic parameters of the interparticle interactions in the near solvation surroundings of H2TPP are characterized. A method is proposed for the evaluation of the change in enthalpies of solvation of macrocyclic molecules based on the values of the heats of evaporation. © 1990.
