Abstract

Titanium-containing molecular sieves are prepared by adding an aqueous template solution to a mixture of tetraalkyl orthosilicate and tetraalkyl orthotitanate, crystallizing the reaction mixture in an autoclave and separating the solid obtained optionally, the solid is washed and calcined. The titanium-containing molecular sieves can be used as catalysts, inter alia in the epoxidation of olefins.
