FIELD: chemistry.
SUBSTANCE: invention discloses a method of producing boron-aluminum silicate zeolite with smaller crystallite size, includes the framework aluminum atoms and framework boron atoms. Zeolite B/Al-ZSM-12 can be used for catalytic processes of selective isomerization of components of the benzene-toluene-xylene fraction and a number of other aromatic hydrocarbons, disproportionation of toluene, as well as hydroconversion of higher alkanes, etc. The synthesized product has a crystallite size of not more than 75 nm, contains in its structure more than 95% framework aluminum atoms and more than 90% framework boron atoms.
EFFECT: obtaining a method of producing boron-aluminosilicate zeolite ZSM-12.
