Реферат:
Influence of the anion X nature in tetraethylammonium compound [N(C2H5)4]X used as SDA in the non-seeded “SiO2 – Al2O3 – Na2O – [N(C2H5)4]X – H2O” reacting system on Beta zeolite formation selectivity was investigated. On the base of crystallization product phase composition as a function of synthesis time, the studied series of anions
may be arranged in the following sequence: F¯, SO42-, PO43-, (CH2COO)22- > HCOO¯ >(COO)22-, CH3COO¯ >> Cl¯ ~ NO3¯ >> Br¯ >> I¯ >> ClO4¯ with decreasing zeolite Beta formation potency from left to right . Particularly, F-
, SO42-, PO43- and succinate anions facilitate formation of Beta zeolite in a wide range of the reaction gel chemical
composition, while ClO4¯, I¯, Br¯ anions prevent the zeolite crystallization. It was experimentally showed that “zeolite-promoting” anions allow to crystallize Beta zeolite in the same wide range of Si/Al composition as it is in TEAOH system, as well as to synthesize the substituted versions of Beta zeolite. The found sequence generally
coincides with the well-known Hofmeister series of anions.
