Studies on the synthesis of ETS-10 II. Use of organic templates

Abstract

ETS-10 has been synthesized using titanosilicate gels and organic templating agents such as choline chloride [OHCH2CH2(CH3)sN+C1 -] and the bromide salt of hexaethyl diquat-5 [Br-(C2Hs)3N+(CH2)sN+(CzHs)3Br-]. The influences of temperature and concentration of the ingredients on the kinetics of synthesis are reported. Physicochemical characterizations of the samples have been carried out by X-ray diffraction (XRD), scanning electron microscopy (SEM), infrared (IR) spectroscopy, nuclear magnetic resonance (NMR) spectroscopy and differential thermogravimetric analysis (DTA)/thermogravimetric analysis (TGA), and adsorption of water, n-hexane and mesitylene. The catalytic activities of H-ETS-10 in the dehydration of n-butanol and in the isomerization of m-xylene and 1,3,5-trimethylbenzene are reported.
