METHOD OF PRODUCING COMPOSITE BASED ON MICROPOROUS ZEOLITE AND MEZOPOROUS SILICON OXIDE Russian patent published in 2017 - IPC C01B39/04 

FIELD: chemistry.

SUBSTANCE: first mixture consisting of tetraethylorthosilicate, water, tetrapropylammonium hydroxide and aluminum isopropoxide is prepared. The second mixture consisting of water, cetyltrimethylammonium bromide and sodium hydroxide is prepared. The first mixture is exposed to microwave radiation at a temperature of 100-115°C. The second mixture is added to the resulting product in a mass ratio of product:second mixture equaling 1:1.5-1.7. The resulting suspension is crystallized under the impact of microwave radiation at a temperature of 180-190°C. The resulting precipitate is separated by centrifuging, washed, dried and calcined to obtain the desired product.

EFFECT: obtaining the desired product with mesopores of larger size than in the desired product produced using the known method, while reducing the time of crystallization.
