Abstract:
The conventional and modified synthesis of titanium silicalite-1 is in the organic system[1,2]. We have reported the TS-1 could be prepared with colloidal SiO2 and TiCl3 as Si source and Ti source respectively in inorganic system[3]. The present paper deals with the ammoximation of cyclohexanone to cyclohexanone oxime over TS-1 prepared by the method described above. Tests are carried out for 5 hours at 65℃,with NH3 and H2O2 in the liquid phase, acetone as solvent, reactants adding to reactor all at once over these two kinds of TS-1. The results show that oxime yield over TS-1 produced in inorganic system is as good as or better than that catalyzed by conventional TS-1 at the same conditions. More over, more satisfied yield of oxinone could be achieved if it reacts at some optimal reaction conditions[4,5]. In addition, the same result has been reached at the epoxidation of propylene catalyzed by these two kinds of TS-1 Following table is the results of reaction catalyzed by these two kinds of TS-1.
