Hydrothermal synthesis of analcime (ANA) with N,N′-dibenzyl-N,N,N′,N′-tetramethyl ethylene diamine
(DBTMED) as template was systematically studied. The various parameters that affect the crystallization of
analcime, temperature, time, Al source and Si/Al ratio were investigated. Systematic variations of these
parameters revealed that this zeolite was obtained from the reaction mixture with the optimized ratio
SiO2/Al2O3=20 in presence of DBTMED comparing to those which obtained by template-free clear solution
with composition SiO2/Al2O3≥ 110. When experiments were conducted at 130 and 150ºC for 96 h, a mixture
of analcime and zeolite P was present in the samples and a pure analcime sample could be obtained at the
range 160 to 180 ºC. The products obtained were characterized by XRD, SEM and IR.
