Field of concentrations and conditions of template structure formation of a silica mesoporous molecular sieves of MCM-48 type

The region of composition and concentration of the reaction mixtures for template structure formation of silica mesomorphous molecular sieves of the MCM-48 type have been determined, the boundary concentrations of the reagents have been determined, and also the effects of synthesis conditions (in particular the ratio of the template and the skeleton-forming elements and the temperature factor) on the structure transformation in the CTAB-TEOS-NaOH-H₂O system. Reproducible methods have been developed for the synthesis of highly ordered MCM-48 with minimization of the amount of surfactant and without the use of additional organic substances. __________ Translated from Teoreticheskaya i éksperimental’naya Khimiya, Vol. 44, No. 3, pp. 186–190, May–June, 2008.
