Аннотация:Approaches to the development of submicron and nanocrystalline silicate materials of MFI structure in a fluorinated surfactant medium were studied with perfluorononanoic acid as an example. In fluorinated surfactants, the crystal structure of the zeolite framework is formed more slowly than in the case of silicalite-1 because of the presence of aluminum atoms. The fractions of the formed Brønsted and Lewis acid sites in zeolites are independent of the amount of aluminum introduced into the reaction mixture. In oligomerization of light alkenes, the activity and operation stability of the synthesized zeolite with lower concentration of Brønsted acid sites and smaller crystal size are similar to those of the commercially available catalyst.
