Effect of solubilization in bitemplate synthesis of a homologous series of organosilica mesophases and mesoporous molecular sieves

Abstract

Peculiarities of bitemplate synthesis of a homologous series of organosilica mesophases (precursors of mesoporous molecular sieves of MCM-41 type) were studied, and an influence of a nature of templating substances and a solubilization on a perfection of their spatial structure was found. n-alkyl(C8–C18)pyridinium halides as solubilizers (micelle-forming surfactants) and monoethanolamides of saturated n-(C10–C16)aliphatic acids as solubilizate were used. Some physicochemical factors promoting a spatial ordering of organosilica mesophases and mesoporous molecular sieves were considered.
