Abstract
The present invention provides a method for preparing a titanium-silicalite molecular sieve, and a method for preparing cyclohexanone oxime using the titanium-silicalite molecular sieve. The method for preparing a titanium-silicalite molecular sieve includes the steps of preparing a mixture of a titanium source, a silicon source and a template agent, wherein the titanium source has a structure of formula (I); heating the mixture to form a gel mixture; mixing the gel mixture with water; heating the gel mixture mixed with the water in a water bath; and calcining the gel mixture mixed with the water. The method using the titanium-silicalite molecular sieve for preparing cyclohexanone oxime results in high conversion rate and high selectivity.
