Epoxidation catalyzed by mesoporous titanium

Copper, titanium, cobalt and iron substituted mesoporous silicas (Cu-, Ti-, Co-, and Fe-HMS) were synthesized with dodecylamine surfactant as templating reagent. Three assembled pathways were used to bond Ti tartrate complex over mesoporous silicas (HMS). The above described catalysts were characterized by XRD and FT-IR, their metal loadings were measured by chemical analysis method. In catalytic testing, Cu-HMS and especially Fe-HMS show the best catalytic activity for hydroxylation of phenol with H2O2 in the presence of water. Ti-HMS and especially Ti tartrate complex assembled HMS catalysts exhibit the best epoxidative activity for catalyzing epoxidation of styrene with rcrt-butyl hydroperoxide. [Pg.312]
