Abstract

The adsorption of acetone from binary and ternary mixtures with n-pentanol, benzene, and n-heptane on completely hydroxylated and silanized silica gel was investigated. The structure of the surface phase and the competition of liquid components for adsorbent surface are discussed on the basis of individual adsorption isotherms. It has been found that the formation of acetone- n-pentanol complexes plays the main role in adsorption on the investigated adsorbents. The structure of the surface layer strongly depends on the character of the hydrocarbon solvent as well as the degree of polarity of the adsorbent surface.
