Summary

Linear alcohols form solid multilayers at the graphite-liquid interface. Even-numbered alcohols consistently form multilayers, while shorter odd-numbered alcohols also show multilayer formation, indicating complex interfacial behavior.

Area of Science:

Physical Chemistry
Materials Science
Surface Science

Background:

Understanding interfacial behavior is crucial in various chemical and physical processes.
Adsorption phenomena at solid-liquid interfaces influence material properties and reaction kinetics.
Linear alcohols exhibit diverse behaviors depending on chain length and molecular structure.

Purpose of the Study:

To investigate the formation of adsorbed solid multilayers of linear alcohols at the graphite-liquid alcohol interface.
To determine the influence of alcohol chain length and parity (even/odd) on multilayer formation.
To characterize the structural and thermal properties of these adsorbed layers.

Main Methods:

Differential scanning calorimetry (DSC) for thermal analysis.
Incoherent elastic neutron scattering for structural investigations.
Neutron diffraction to probe the arrangement of adsorbed molecules.

Main Results:

All studied linear alcohols (C5-C18) form at least one adsorbed monolayer at the graphite-liquid interface.
Even-numbered alcohols (C6OH-C18OH) consistently exhibit multilayer formation.
Shorter odd-numbered alcohols (C5OH-C11OH) show distinct features indicative of multilayer formation, unlike longer odd-numbered alcohols.

Conclusions:

Linear alcohols can form stable solid multilayers at the graphite-liquid interface.
The formation of these multilayers is dependent on both the chain length and parity of the alcohol.
Neutron scattering and calorimetry provide powerful tools for elucidating interfacial structures and phase behavior.
