The heats of adsorption on weakly activated γ-aluminium oxide for a number of linear alkanes (from n-butane to n-nonane) and for 2.2.4-trimethylpentane have been determined by GSC and extrapolated to zero surface coverage.The dependance of the adsorption energy on the number of carbon atoms is discussed on the basis of the bidimensional gas model: it is shown that the interactions of the adsorbates with the oxidic surface are mainly due to London dispersion forces.

Adsorption Heats

The heats of adsorption on weakly activated γ-Al2O3 of a number of linear 1-monoolefins (C4 to C9) and cyclic saturated and unsaturated hydrocarbons have been measured by gas-solid chromatography and extrapolated to zero surface coverage.The double bond contribution to the adsorption energy is shown by comparison of the adsorption heats with those of the corresponding saturated molecules and is related to the existence of Brensted acid centers on the adsorbent surface. The effect of cyclization is also shown.

Bi(2-C4H3S)3 shows an enantiotropic phase transition that is dominated by London dispersion forces. DFT calculations on model compounds were carried out in order to investigate the competition between Bi⋯S and Bi⋯π heteroarene interaction.
