METHOD OF STABILISING MESOSTRUCTURE OF MSM-41 TYPE SILICATE MATERIALS

摘要

FIELD: chemistry.;SUBSTANCE: invention relates to synthesis of a MSM-41 type mesoporous material. The method involves stabilisation of the structure of the material during synthesis thereof, according to which the step for hydrothermal treatment in an autoclave is carried out while continuously stirring the reaction mixture at 105-135°C for 2-4 hours with molar ratio of reagents 1SiO₂:0.6±0.2NH₄Cl:1.6±0.2NH₃:150H₂O.;EFFECT: invention enables effective stabilisation of the mesostructure of MSM-41 material with low pressure of saturated vapour in the autoclave.;2 dwg, 2 tbl, 2 ex
