Abstract：

Ti-MWW　was　prepared　by　acid　treatment　and　calcination　on　a　lamellar　precursor,　which　was　synthesized　under　dynamic　hydrothermal　crystallization　conditions　using　piperidine　as　a　template　and　boric　acid　as　a　structure-supporting　agent.　The　influences　of　acid　treatment　and　the　synthesis　conditions　on　its　catalytic　performances　were　studied　by　the　epoxidation　of　allyl　alcohol　(AAL)　with　H2O2.　Acid　treatment　for　>　16　hr　could　transform　the　extra-framework　Ti　into　the　anatase　phase.　The　catalytic　performance　of　Ti-MWW　decreased.　Ti-MWW　with　Si/Ti　=　20:1　treated　with　15%　HNO3　at　353　K　for　12-16　hr　showed　the　highest　activity　and　selectivity.　AAL　conversion　and　GLY　selectivity　in　30　min　at　333　K　reached　88.7　and　99%,　respectively.　Ti-WMM　showed　perfect　catalytic　performance　and　wide　application　prospects　in　the　AAL　epoxidation.
