DTA investigations of n-octadecanol films on complex carbon-silica adsorbents as a method for determination of their surface properties

Summary The properties of n-octadecanol films on complex carbonsilica adsorbents were investigated. It was found that two forms of oriented surface film exist on Carbosil surface. The structure of each form of the film distinctly depends on the nature of the surface patches of Carbosil. It was shown, using differential thermal analysis that it is possible to determine the ratio of carbonized and hydroxylated parts of the Carbosil surface.
