Titanium silicalite-1 (TS-1), first synthesized by Enichem in Italy in 1983, has been paid much attention because of its excellent catalytic and oxidative performance with H2O2 under the mild reaction conditions.

A of Italy successfully developed a new technology in which the ammoxidation of cyclohexanone was catalyzed by titanium silicalite-1.

Oxidative desulfurization of gasoline using hydrogen peroxide over titanium silicalite molecular sieves;

Titanium silicalite molecular sieves are a type of heteroelements-containing molecular sieves which are comprised of Ti-0 tetrahedrons and S:-0 tetrahedrons.

Advances in study of deactivation and regeneration of titanium silicalite;

Removal of organic sulfur from crude benzene over titanium silicalite using hydrogen peroxide;

Titanium silicalite (TS-1) was successfully synthesized with tetrapropylammonium bromide (TPABr) as the templates, titanium tetrachloride as Ti source and colloidal silica as Si source.

Liquid-phase epoxidation of allyl chloride with hydrogen peroxide was carried out over Ti-MWW,a novel titanosilicate with the MWW structure,to synthesize epichlorohydrin selectively and effectively.

A novel bifunctional catalyst that exhibits catalytic activity for both the epoxidation of olefins and the carbonation of organic epoxides has been prepared through grafting quaternary ammonium halide on a titanosilicate.

The preparation methods and catalytic properties of the novel titanosilicates essentially with the MWW structure have been summarized.

Study of extruded titanium silicalite molecular sieve;

H→ 13 C CP/MAS NMR spectroscopy was used to trace the template role of TPAOH in the process of forming titanium silicalite molecular sieve.

XRD and FT-IR spectroscopy were used to trace crystallization course in the forma-tion of titanium silicalite molecular sieve, and its crystallization mechanism was discussed.
