Abstract.

The isothermal gas adsorption of two hexane isomers (n-hexane and cyclohexane) in the mesopores of MCM-41 silica have been investigated by small angle neutron scattering (SANS). This has been achieved by performing SANS measurements under contrast matching conditions for the silica matrix and condensed hydrocarbon confined in the mesopores. Insight into the kinetics of adsorption have been derived from changes in the intensity of the (100) diffraction peak associated with the ordered hexagonal mesoporous structure of the MCM-41 silica.
