More Information
Summary:The invention belongs to the technical field of preparation of ethyl levulinate and particularly relates to a method for preparing ethyl levulinate by using straw-type biomass. According to the method, lignin in cellulose biomass is removed by ethanol extraction, alcoholysis esterification is performed, and both ethanol lignin and ethyl levulinate are obtained, so the utilization rate of raw materials is improved. Moreover, the method has the advantages of short reaction time, less side reaction and high product concentration.
