METHOD FOR ACCELERATED PREPARATION OF MESOPOROUS AND MESOSTRUCTURED MCM-41 TYPE SILICATE MATERIALS

摘要

FIELD: silicon-containing materials. ^ SUBSTANCE: method comprising preparation of silicate materials from alcohol-ammonia reaction medium followed by hydrothermal treatment is characterized by following molar ratios of reactants: 1 C8H20O4Si : 0.2±0.02 cetyltrimethylammonium bromide : 22±2.2 NH3 : 50±5 C2H5OH : 475±50 H2O and by that further hydrothermal treatment of materials is performed in continuously rotated autoclave at 120±15°C for 2-4 h. ^ EFFECT: increased thermal, hydro- and mechanical stability. ^ 1 dwg, 2 ex
