Abstract

Titanium silicalite - 1(TS - 1) was synthesized from inorganic reactant system using cheap colloidal silicon and TiCl3 aqueous solution as the silicon and titanium sources, respectively, TPABr as the templating agent, and diethylamine, n - butylamine, ammonia as base to provide the alkalinity necessary for crystallization. The TS - 1 synthesized from the inorganic reactant system has been demonstrated to have the same characteristics with the standard TS - 1 from organic synthesis system by XRD, IR, UV - vis, SEM, elemental analysis and N-2 adsorption/desorption. The influence of various synthesis parameters such as base source, SiO2/TiO2 ratio, N-2 protection, seedcrystals, amounts of template, silicon source and crystallization time hasbeen investigated in detail. It has been shown that the control of basicity of the reaction mixture is critical for the synthesis; N-2 protection is essential when reactants were mixed; adding seeds can greatly facilitate the formation of the TS - 1 crystal; there is a critical value for the minimum amount of TBABr required to crystallize TS - 1; TS - 1 crystals obtained with colloidal silicon are usually large.
