CONVERSION OF CARBOHYDRATES TO LEVULINIC ACID ESTERS

摘要

The present invention relates to the field of converting carbohydrates into levulinic acid, a platform chemical for many chemical end products. More specifically the invention relates to a method for converting carbohydrates such as mono-, di- or polysaccharides, obtained from for example biomass production into a suitable levulinic acid ester in the presence of a zeolite or zeotype catalyst and a suitable alcohol, and the ester may be further converted into levulinic acid if desired.

主权项

1. A method of converting saccharide(s) into levulinic acid ester, comprising heating said saccharide(s) to a suitable temperature in the presence of a suitable zeolite or zeotype catalyst with a pore size diameter of at least 6 Å and a solvent selected from suitable alcohols in a pressurized batch reactor.
