Abstract:
1. A method for preparing a titanium-silicalite molecular sieve, comprising 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) wherein R 1 , R 2 , R 3 and R 4 are independently C 1 -C 10 alkyl, C 1 -C 10 alkoxy, C 2 -C 10 hydroxyalkyl, in which R 5 and R 6 are independently C 1 -C 3 alkyl, and at least two of R 1 , R 2 , R 3 and R 4 have a carbon number more than 4; 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.
