摘要：

Pure MFI and MEL zeolites were obtained at 170 degrees C from clear solutions of general composition SiO2: 0.0004 Al2O3: 0.30 Na2O : aTAABr (or TAAOH) : 40H(2)O with a = 0.03 -0.16 and TAA = TEA, TPA or TEA. The physicochemical characteristics (XRD, SEM, d.t.g., d.t.a., FT i.r., and multi-n.m.r.) allow one to compare the products obtained from the clear solution with those obtained from a hydrogel.
