摘　　要：The synthesis of titanosilicalite has become a hotspot in the zeolite catalytic fields. In this paper, TS 1 zeolite samples were synthesized with tetrapropyl ammonium bromide as the template, with ammonia as the base source and with the mixture of titanium tetrachloride and tetrabutyl orthotitanate as the titanium source. The TS 1 samples have excellent catalytic performance in epoxidation of propylene with aqueous hydrogen peroxide. The samples were characterized by XRD and IR. The introduction of chlorine decreases the association degree of titanium alkoxides and it may prevent preferential segregation of titanium and silicon.The synthesis of titanosilicalite has become a hotspot in the zeolite catalytic fields.
