✦ Synopsis

Thermally stable titanium pillared montmorillonite has been prepared by the intercalation of four different titanium alkoxides. X-ray diffraction, BET, chemical analysis, thermogravimetric analysis, differential thermal analysis, temperature-programmed desorption of ammonia and IR spectra of samples allow the determination of the structure. The catalysts prepared from Ti(OBt), present the most interes$.ing structural properties after calcination. The titanium pillared montmorillonita with pillars of ca. 12 A shows high activity in the dehydration of 1-butanol. The selectivity of the catalyst is directly related to its acidic properties.

Titanium-pillared inter-layered clays (TiPILCs) were prepared by intercalating polymeric cationic species in clay layers. The intercalation was obtained by hydrolysis of TiCl, with HCl (TiPILC-Cl) and HISO, (TiPILC-S). The influence of the determinant parameters viz. the H+/Ti and Ti/clay ratios, wa
