Diffuse X-ray scattering near a two-dimensional liquid–vapor phase transition at the n-hexane–water interface

Abstract

The molecular structure of neutral n-triacontanol mesophases at the n-hexane–water interface has been studied by diffuse X-ray scattering using synchrotron radiation. According to the experimental data, a transition to the multilayer adsorption of alkanol occurs at a temperature below the transition from a gas phase to a liquid Gibbs monolayer.
