Abstrakt: Using the method of mass-spectroscopic thermal analysis, it has been shown that when the surface of rutile is modified with n-butylamine and acetic acid, it is possible for the two substances to interact in the surface layer, with the result that the order in which the amine and the acid are adsorbed affects the structure of the resulting adsorbed layers. The chemisorbed layer on the surface of a sample of TiO-AA-BA consists of molecules of both modifiers and the product of their surface reaction. Acetic acid adsorbed on TiO-BA displaces the coordinatively bound amine molecules from the surfaces, leading to the formation of butylacetamide and the chemisorption of the acid molecules on unoccupied areas of the TiO surface.
