Single crystals of ZSM-5 were synthesized in three systems containing Na + -TPA, Li + -TPA, and NH 4 + -TPA, respectively. Applying a reaction mixture of the molar composition 8 TPA + 123(NH 4 ) 2 O + Al 2 O 3 + 59 SiO 2 + 2280 H 2 O, alkaline-free, homogeneous, and pure single crystals of ZSM-5 were prepared up to a length of 350 μm. The crystal size and yield were found to be dependent on the water content of the starting reaction mixture and on the type of aluminium source; for example, boehmite and aluminiumtriisopropylate.
