Abstract: High-Speed Experimentation (HSE) techniques are newly developed methods allowing the fast preparation of large numbers of parallel experiments to screen an extensive parameter space. These techniques are particularly useful to investigate chemical systems for which a precise knowledge of the overall mechanism of reaction is not available. Here we report the application of HSE techniques to the study of the synthesis of two families of silicate-based compounds: zeolites and silsesquioxanes. In both cases many parameters influence the synthesis determining which structures are formed and in which amounts. Zeolites are well-¬known crystalline microporous materials with broad applications as heterogeneous catalysts. Silsesquioxanes are small, discrete siloxane cages used both as homogeneous catalysts and as model compounds for silica surfaces and zeolites. With our HSE approach we were able to investigate the synthesis of aluminium-rich zeolite beta (Si/Al ratio from 2.5 to 5) and to identify a new and efficient (fast, low cost) way to synthesise silsesquioxane precursors for Ti-catalysts active in the epoxidation of alkenes.
