Abstract

Titanium-containing MCM-41 was prepared from the synthesis gel derived from Ti(OC 4H 9) 4 and several Si sources. By using tetraethyl orthosilicate (TEOS), which is free from Al and Na, as a silica source, we were able to incorporate titanium into the framework of MCM-41 without the formation of anatase. Ti-MCM-41 was applicable to the oxidation of bulky alkenes with H 2O 2 or t-butyl hydroperoxide (TBHP) as an oxidant. The stability of Ti-MCM-41 against water was low compared to pure-silica MCM-41.
