PCT No. PCT/FR96/01209 Sec. 371 Date May 4, 1998 Sec. 102(e) Date May 4, 1998 PCT Filed Jul. 31, 1996 PCT Pub. No. WO97/05060 PCT Pub. Date Feb. 13, 1997A method is provided for preparing fully lattice-inserted titanium zeolites by post-synthesis processing of the synthetic zeolite optionally containing titanium with an inorganic acid, wherein the post-synthesis processing comprises processing the zeolite in the presence of at least one titanium source with a solution containing at least one oxidizing inorganic acid having a higher redox potential than an acidic tetravalent titanium solution. The invention is also directed to the use of the zeolites.
