【Abstract】 The catalysts for synthesis of 1,4-dioxane by cycl od ehydration of diethylene glycol were reviewed. Liquid catalysts, solid acid cata lysts, macroreticular cation exchange resins, heteropolyacid, heteropolyacid sal t catalysts and zeolite were introduced. The yield and selectivity of each catal yst used were presented.更多还原
