Method for the production of a titanium-containing zeolite

Production of a titanium-containing zeolite comprises: (a) hydrolyzing a mixture of hydrolyzable silicon (Si) and titanium (Ti) compounds with a quaternary ammonium base in an aqueous medium in amounts such that the Si/Ti molar ratio is at least 30 and the nitrogen/silicon (N/Si) molar ratio is 0.12...

More Information
Summary:Production of a titanium-containing zeolite comprises: (a) hydrolyzing a mixture of hydrolyzable silicon (Si) and titanium (Ti) compounds with a quaternary ammonium base in an aqueous medium in amounts such that the Si/Ti molar ratio is at least 30 and the nitrogen/silicon (N/Si) molar ratio is 0.12-0.2; and (b) crystallizing the resulting gel at 150-220 degrees C for less than 3 days. An Independent claim is also included for a Ti-containing zeolite produced by the above process, having a primary crystallite size of 0.1-2.0 mu m.
