Synthesis and catalytic properties of titanium containing extra-large pore zeolite CIT-5
Original language description
Titanium containing extra-large pore zeolite CIT-5 (IZA code: CFI) was successfully prepared by direct synthesis using Cab-O-Sil M5 and titanium(IV) butoxide in the presence of LiOH. N-Methylsparteinium hydroxide was used as a structure directing agent.The product crystallized into thin plate crystals with an approximate size of 20 x 5 x 0.2 mu m. The lowest achieved Si/Ti ratio was 23. The necessary duration of hydrothermal synthesis increased with increasing concentration of Ti in the reaction mixture from 11 days (Si/Ti = 63 in product) to 17 days (Si/Ti = 36) at 155 degrees C. Prepared Ti-CFI samples exhibit BET surface areas in the range of 308-346 m(2)/g and micropore volumes of 0.094-0.097 cm(3)/g. CFI possesses extralarge pores (14-ring, 7.2 x7.5 A) accessible for bulky molecules, therefore, Ti-CFI is a useful catalyst for epoxidation of double bonds in bulky molecules used in perfumery and pharmacy. The Ti-CFI samples proved to be catalytically active in epoxidation of 1-oct
