Abstract: Levulinate esters have been recognized as an important platform chemicals and have a wide range of applications. This article summarizes the route of biore?nery，and then presents the up-to-date development of biorefinery in technologies and applications. Three routes of levulinate esters production are introduced，which include the route of synthesis reaction from levulinic acid，the route of conversion from furfuryl alcohol and the route of cellulosic biomass alcoholysis；and the advantages and disadvantages were also compared. Finally，for further application，the direct alcoholysis of biomass to produce levulinate esters will be the future trend. It is necessary to obtain the thermodynamic properties and other data during the reaction of direct alcoholysis of biomass and to strengthen the research with the related subjects，so as to build the theory foundation of the direct alcoholysis of biomass to produce levulinate esters.

Key words: levulinate esters, biore?nery, alcoholysis, levuniate acid
