Abstract
The present invention concerns a method for the production of a titanium-containing zeolite whereby a synthesis gel is formed by combining and hydrolysing a hydrolysable silicon compound, a hydrolysable titanium compound and a basic quaternary ammonium compound in an aqueous medium, in quantities such that relative to the starting compounds the molar ratio of Si/Ti is greater than or equal to 30 and that of N/Si is 0.12 to less than 0.20, and the synthesis gel is then crystallised at a temperature of 150 ° C. to 220 ° C. for a period of less than 3 days, and a titanium-containing zeolite obtainable by this method.
