Process for preparing microporous crystalline titanium silicate

摘要

A process for the preparation of crystalline microporous titanium silicates using ethylsilicate-40 and titanium peroxide as silicon and titanium sources respectively is described. The process permits a significant decrease in the production cost of titanium silicate containing higher amount of titanium (Si/Ti=20) because of cheaper raw materials as well as reduction in the quantity of tetarpropylammonium hydroxide (TPAOH) template (SiO2:TPAOH=1:0.06-0.1) required for preparation. The material obtained by the present invention is useful as an active catalyst in the reactions such as oxidation of hydrocarbons, alcohols, sulphides, and thioethers.
