Ethyl levulinate

Ethyl levulinate is an organic compound with the formula CH₃C(O)CH₂CH₂C(O)OC₂H₅. It is an ester derived from the keto acid levulinic acid. Ethyl levulinate can also be obtained by reaction between ethanol and furfuryl alcohol.^[3] These two synthesis options make ethyl levulinate a viable biofuel option, since both precursors can be obtained from biomass: levulinic acid from 6-carbon polymerized sugars such as cellulose, and furfural from 5-carbon polymerized sugars such as xylan and arabinan.
