摘要：

Data on the optimization of alkalinity of the reaction mixture and the reaction temperature in the formation of the siliceous porous mesophase material C-16-SiO2-MMM are presented. A criterion for the evaluation of the level of structure optimization for mesoporous mesophases is formulated. Measurements of the texture parameters of the materials treated in acidic media led to the assumption that the walls in the pure siliceous C-16-SiO2-MMM system consist of separate blocks, which, apparently, are not bound completely to one another by chemical interactions.
