A series of SO3H-functionalized polymers were prepared and employed as heterogeneous catalysts for one-pot transformation of\nfructose into 5-ethoxymethylfurfural (EMF) that is considered to be one of potential liquid biofuels. A high EMF yield of 72.8%\ncould be obtained at 110�°C for 10 h, and the polymeric acid catalysts could be recycled for five times without significant loss of\ncatalytic performance.
