When the solute becomes the solvent: orientation, ordering, and structure of binary mixtures of 1-hexanol and cyclohexane over the (0001) α-Al2O3 surface.

Mixtures of 1-hexanol in cyclohexane over the (0001) α-Al(2)O(3) surface were probed in the CH stretching region using vibrational broadband sum frequency generation (SFG). Below 10 mol % 1-hexanol, the alcohol adsorbs to the surface through interactions that result in observed free adsorption energies of around 14-15 kJ/mol obtained from the Langmuir… CONTINUE READING
