Under the studied conditions for synthesis of mesophase materials, with the increase of the length of alkyl radical of alkylpyridinium halides the density of packaging of their molecules in packet micelles also in- creases. The differences in the packaging density of the molecules of these surfactants essentially stipulate the degree of perfection of the hexagonal structure and the features of sorption properties of the resulting mesophase MCM-41 materials.


Key words template, alkylpiridinium halide, MCM-41, structure order, sorption, X-ray analysis.
