Titanium silicalite TS-1 is environmentally friendly catalyst, catalytic oxidation system and dilute hydrogen peroxide solution TS-1/H2O 2 overcome the traditional craft serious pollution, harsh reaction conditions, complex operation The drawback in many organic reactions, exhibits excellent catalytic performance. The successful application of the system in the field of catalytic oxidation, known as the \To participate in an organic reaction of TS-1 carbon is very serious, life is short, which largely prevents the TS-1 of a wide range of applications. Therefore, it is very necessary to find a method to extend the life of TS-1. The angle of departure from the mitigation of the TS-1 carbon, two different catalysts were prepared. First, in order to the modified TiO 2 for the titanium source, and succeeded in preparing a powder with a lower content of strongly acidic centers TS-1; cordierite carrier, using a coating method, the preparation of TS- / cordierite monolithic catalyst, which is in addition able to solve the difficult problem of TS-1 powder separation, but also increase the relative speed between the TS-1 with the reaction liquid phase, to reduce the the outer diffusion resistance of the reaction product, is conducive to the reaction product diffusion of TS-1 carbon mitigation. To modified TiO 2 the titanium source preparation powder TS-1, With the help of FT-IR and UV-vis technology, effects of different titanium silicon molar ratio of different crystallization time and 0.5 M HCl solution post-processing factors such as different times of TS-1 structure, framework titanium and non-framework titanium content. The results showed that the the modified TiO 2 less than the classic method for the synthesis of titanium source of TS-1 strongly acidic centers; synthesis process, the modified TiO to 2 amount of high or low are not suitable, and the most modified TiO 2 in the crystallization 24h into the framework; 0.5M HCl solution for 24h to think that the powder TS-1 processed completely. Herein, the powder TS-1 catalyzed cyclization of cyclohexanone oxime ammonia reaction results were as follows: The cyclohexanone conversion was 94.04%, cyclohexanone oxime in a yield of 90.13%, the selectivity of the reaction was 95.84%. Preparation of TS-1 / cordierite monolithic catalyst, the paper examines the factors of the coating, the solvent viscosity, and immobilized. When the coating is applied, a single coating time 3min coating (TS-1); preparation of TS-1 slurry viscosity of the solvent has little influence of TS-1 coated; results showed that ultrasonic treatment, coated with TS- Good mechanical strength of the coating, combined with the surface of the cordierite is very strong. Cyclohexanone ammoximation continuous operation reaction evaluation prepared by the TS-1 / cordierite monolith catalyst, the catalyst was found after 117h, the quality of the coating of TS-1 was dropped from 3.0922g 2.9702g, lost only 0.122 g; life than powder TS-1 is longer; after the circulation amount is increased to make the decreased activity of TS-1 / cordierite monolith catalyst of the catalytic effect of rebound.
