| 摘要 |
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.
