The present invention concerns a method for the production of a titanium-containing
zeolite by: (a) combining a hydrolyzable silicon compound and a hydrolyzable titanium
compound; (b) adding a basic quaternary ammonium compound in an aqueous medium
to the mixture from (a) and hydrolysing the reaction mixture at a temperature in
the range from 0 C. to 100 C. to form a synthesis sol; then (c) heating
the synthesis sol to a temperature in the range from 150 C. to 190
C.; and (d) crystallizing the synthesis sol at this temperature, characterized
in that the heating-up time in step (c) is less than 240 min.
