Abstract: | The thermodynamic characteristics of adsorption equilibria of primary aromatic alcohols and thiols on graphitized carbon black at 300 K were determined by the molecular-statistical method. The influence of intramolecular effects under the action of the force field of the sorbent on the conformation of the molecules studied was considered in comparison with n-alkylbenzenes having similar structures. An increase in the chain length by one-CH2 group was shown to influence the formation of intramolecular H-bonds in alcohol and thiol molecules. In adsorption, a considerable fraction of molecules assumed configurations close to planar. An exception was the nonplanar conformation of the 2-phenylethanol molecule stabilized by the intramolecular H-bond. |
