STRUCTURE-ACTIVITY-RELATIONSHIPS IN ADSORPTION AND CHEMISORPTION OF ORGANIC-COMPOUNDS ON METAL-OXIDE SURFACES

The application of several physicochemical parameters of organic compo und structures for description of their nonspecific and specific inter actions at adsorption on the oxide surface as well as for chemisorptio n kinetics in these systems is discussed. An approach to calculate the distribution functions on the coefficients of linear equations, conne cting 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 equ ilibria and chemisorption kinetics of organosilicon compounds on the S iO2 surfaces and for determination of the dispersive and specific comp onents of the free surface energy of Si, Ti, and Al oxides.
