PROCESS FOR THE TRANSFORMATION INTO AN AQUEOUS MEDIUM OF THE CARBOHYDRATES PRESENT IN A BIOMASS INTO ALKYL LEVULINATES

摘要

The invention relates to a method for converting the carbohydrates present in a biomass into alkyl levulinates which consists in an esterification of said biomass in an acidic aqueous medium and in the presence of at least one alkene and which is characterized in that said alkene is a disubstituted alkene the number of carbon atoms of which is greater than or equal to 7 and which comprises at least one ring, said at least one ring having a number of carbon atoms between 5 and 7 and containing the double bond of alkene.
