Titanium-silicalite molecular sieve and the method for its preparation |
摘要 |
The present invention relates to a titanium-silicalite (TS-1) molecular sieve and the method for preparation of the same, wherein each crystallite of said titanium-silicalite molecular sieve has a hollow cavity with a radial length of 5-300 nm. The benzene adsorption capacity of the molecular sieve determined at 25° C. and P/P0=0.10 for 1 hour is at least 70 mg/g; and the method for preparation of said molecular sieve comprises an acid-treatment and then an organic-base treatment of the synthesized TS-1 molecular sieve, or only an organic-base treatment. The TS-1 molecular sieve of the present invention has a relatively high reactivity and activity stability in the catalytic oxidation.
