A novel synthetic crystalline molecular sieve designated as SSZ-109 is disclosed. SSZ-109 is synthesized using a structure directing agent comprising one or more of N,N,N,N-tetramethyl-N,N-diisobutylhexane-1,6-diammonium cations, N,N,N,N-tetramethyl-N,N-dineopentylhexane-1,6-diammonium cations, and N,N,N,N-tetramethyl-N-isobutyl-N-neopentylhexane-1,6-diammonium cations.

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 metal source selected from IIA to IVA elements and a template agent; 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.
