From cellulose raw material,a variety of technical routes for the synthesis of ethyl levulinate are summarized.Through comparing advantages and disadvantages of technical routes,the direct alcohol hydrolysis of cellulose is preferred,and the key reaction mechanism of the formation of ethyl levulinate under the direct alcoholysis of cellulose is explored.In addition,the research progress in the catalysts for preparation of ethyl levulinate is reviewed,and three existing problems in this field are discussed.The selection of suitable biomass varieties is emphasized,and the development of catalysts in this field is introduced.
