“Structure−Activity” Relationships in Adsorption and Chemisorption of Organic Compounds on Metal Oxide Surfaces

The application of several physicochemical parameters of organic compound structures for description of their nonspecific and specific interactions at adsorption on the oxide surface as well as for chemisorption kinetics in these systems is discussed. An approach to calculate the distribution functions on the coefficients of linear equations, connecting the adsorption or chemisorption parameters on the heterogeneous surface with physicochemical parameters of adsorbates or reagents, is presented. It has been used for the description of some adsorption equilibria and chemisorption kinetics of organosilicon compounds on the SiO<INF>2</INF> surfaces and for determination of the dispersive and specific components of the free surface energy of Si, Ti, and Al oxides.
