英文摘要：In this paper, several technical routes for the preparation of ethylene glycol was briefly explained. The current research of one-pot synthesis of ethylene glycol by oxidative hydration of ethylene with titanosilicate catalysts was analyzed and summarized. The main reasons for the decreased activity of titanosilicate catalysts were discussed. In the end, the development of ethylene oxidized to ethylene glycol in one-pot by titanosilicate catalysts in the future is prospected.
