Abstract
Carbohydrates as derived from plant biomass can be converted into mono-alcohols, diols, and/or bi-functional alcohols or into carboxylic acid derivatives. By catalytic transesterification of such carbohydrate derivatives, ester-type diesel-fuel blendstock components may be produced. More specifically, alkyl levulinates are catalytically trans-esterified with hydroxyl-functionalized compounds where both the alcohols and the alkyl levulinates are derived from biomass carbohydrates. Esters produced in this way show physicochemical characteristics that make them suitable for use as diesel fuel blendstock.
