ABSTRACT:
A process for producing a titanium-containing zeolite such as TS-1 titanium silicalite is disclosed. A precursor mixture comprising a silica source such as tetraalkylorthosilicate, a titanium source such as titanium alkoxide, a growth medium comprising a nitrogen-containing organic base such as an amine, a fluoride-containing mineralizing agent such as hydrogen fluoride, and an optional organic solvent, is formed then heated to yield the titanium-containing zeolite as solid crystals. A controlled amount of water may be present in the growth medium. The process is capable of providing good yields of high purity zeolites containing framework titanium atoms even in the absence of a quaternary ammonium salt.
