Preparation of levulinic acid from fructose using an acid catalyst, a polyethylene glycol and an end-capped polyethylene glycol

摘要

A method of preparing levulinic acid comprising:combining a fructose source, at least one of polyethylene glycol and end capped polyethylene glycol, and an acid catalyst to form a reaction mixture;heating the reaction mixture to a temperature and for a time sufficient to promote an acid-catalyzed dehydration reaction of fructose in the fructose source and to form levulinic acid in a product mixture; andisolating levulinic acid from said product mixture.
