The present invention provides a titanium-silicalite molecular sieve and a method for preparing the same. The method includes the steps of preparing a mixture of a titanium source, a silicon source, a transition metal source, a template agent and water; heating the mixture to form a gel mixture; heating the gel mixture in a water bath; and calcining the gel mixture after the gel mixture in the water bath to form the titanium-silicalite molecular sieve. The present invention further provides a method for preparing cyclohexanone oxime by using the titanium-silicalite molecular sieve as the catalyst which results in high conversion rate, high selectivity and high usage efficiency of hydrogen peroxide.

The present invention provides a method for preparing a large-sized titanium-silicalite molecular sieve, and a method for preparing cyclohexanone oxime using the large-sized titanium-silicalite molecular sieve. The method for preparing a large-sized titanium-silicalite molecular sieve includes preparing a mixture of a titanium source, a silicon source and a template agent; heating the mixture to form a gel mixture; mixing a colloidal silica with the gel mixture; heating the gel mixture mixed with the colloidal silica in a water bath; and calcining the gel mixture mixed with the colloidal silica. In the present invention, the average particle size of the large-sized titanium-silicalitem molecular sieve is more than 10 um, and the particle size distribution is centralized, so as to avoid the formation of titanium-oxygen-titanium bonding. The method for preparing cyclohexanone oxime using the large-sized titanium-silicalite molecular sieve results in high conversion rate, high selectivity and easy recovery.

摘要:
A flexible radio frequency identification label and a method for fabricating the same are proposed. A first flexible protection layer is attached to a second flexible protection layer to form a closed space for receiving a radio frequency identification circuit. By such arrangement, a good flexibility can be provided by the flexible protection layers, and the closed space also enables the radio frequency identification circuit to be protected and isolated from the moisture in the outside environment, such that the circuit can be prevented from being oxidized and the service life of the product can be extended.
