Abstract

Adsorption of n-alkanes (C7H16–C11H24), cyclohexane, benzene, CHCl3, CCl4, and ClCH2CH2Cl by polymethylsilsesquioxane [MeSi(OH)0.4O1.3]n was investigated by inverse gas chromatography in the Henry region. The adsorption isotherms are linear for all adsorbates. The standard changes in the thermodynamic parameters of adsorption were determined. The absence of specific selectivity with respect to aliphatic, cyclic, or aromatic hydrocarbons or chloroalkanes indicates that the adsorbent is chemically homogeneous.
