Abstract: The synthetic pathways of levulinic acid and alkyl levulinates were introduced. The synthetic routes of levulinic acid mainly includes catalyzed hydrolysis of furfuryl alcohol, direct hydrolysis of biomass and hydrolysis of hemicellulose. The synthetic pathways of alkyl levulinate were esterification of levulinic acid, direct alcoholysis of biomass, alcoholysis of furfuryl alcohol and alcoholysis of 5-chloro methyl furfural. Recent research of solid catalysts used in conversion of biomass into levulinic acid and alkyl levulinates were reviewed, and the brief overview of the solid catalyst types that used in biomass conversion such as super acid, molecular sieve, heteropoly acid and resin was conducted. Furthermore, the development and application in the future of solid catalyst were also prospected.

Key words: levulinic acid, alkyl levulinates, biomass, solid catalyst
