Abstract
EMT- and FAU-type zeolites were prepared by using a mixture of organic molecules, i.e., crown-ether + ethylene glycol or crown-ether + 1,3,5 -trioxane. The products were characterized by elemental analysis, XRD, SEM, thermal analysis, n-hexane adsorption, and n.m.r. spectroscopy. Depending on the method used to prepare the starting gel, the solids o btained showed different characteristics. D.t.a. proved to be a good t ool to determine, from the thermal decomposition of the organic templa tes the presence of structure defects in the EMT and FAU samples.
