Mesoporous　W-MCM-22　molecular　sieves　were　prepared　for　the　first　time　by　directly　hydrothermal　synthesis　using　silica　gel　as　the　source　of　silicon,　sodium　tungstate　as　the　tungsten　source,　piperidine　as　a　structure-directing　agent　(SDA)　and　boric　acid　as　a　structure-supporting　agent　under　dynamic　state.　The　catalyst　was　characterized　and　analyzed　by　powder　X-ray　diffraction　and　UV-visible　spectroscopy.　The　influence　of　tungsten　content　on　catalytic　performance　for　epoxidation　of　allyl　alcohol　was　investigated.　The　catalytic　performances　of　W-MCM-22　with　different　ratio　of　n(Si)/n(W)　were　compared　with　the　zeolite　of　MCM-22　without　adding　sodium　tungstate　in　synthesis.　The　results　showed　that　the　mesostructure　of　MCM-22　was　maintained　very　well　in　W-MCM-22　as-synthesized　when　the　ratio　of　n(Si)/n(W)　was　above　40　in　the　gel.　The　tungsten　atoms　entered　the　framework　dispersively,　and　there　was　no　any　kind　of　tungsten　oxide　in　the　framework.　The　W-MCM-22　with　n(Si)/n(W)　of　40　in　the　gel　showed　better　catalytic　performance　obviously　than　MCM-22　for　epoxidation　of　allyl　alcohol　to　glycidol,　with　hydrogen　peroxide　as　oxidant　in　aqueous.
