Isotherms of adsorption of heptane molecules at 303 K on hybrid bionanocomposite diacetatecellulose-silica (DAC-silica) have been investigated. Isotherm of adsorption can be described by three-member equation of theory of volume filling of microspores from the initial part before filling. It was determined that differentional heat of adsorption on n-heptane molecules on DAC-silica nanocomposite is stepped and at this interaction adsorbent-adsorbate has carried out with evaluation heat 94 kJ/mol and at quantity of adsorbate more than 0,5 mmol/g interaction adsorbate-adsorbate has been observed, adsorption can be described as polymolecular. On the base of curve of differentional molar entropy has been shown that molecules of n-heptane are in solid state in adsorbent before 0,55 mmol/g.
