FIELD: chemistry.
SUBSTANCE: described is method of regulation of crystal microporous silicoalumophosphte structure with structure SAPO, free of admixtures of other crystal microporous silicoalumophosphtes, by introduction in water initial reaction mixture, which contains sources of aluminium and silicon, of phosphoric acid, as well as organic structure-forming compound - di-n-dibytylamine, inoculating crystals of target phase, namely, crystal microporous silicoalumophosphtes, free of admixtures of other crystal microporous silicoalumophosphtes, with further crystallisation of prepared mixture in hydrothermal conditions,necessary for formation of crystals with zeolite-like structure, separation and drying of obtained material.
EFFECT: obtaining phase-pure product of crystallisation.
