Title: HMF production from glucose in ionic liquid media

Abstract

Methods of converting lignocellulosic derivatives form 5-hydroxymethyl furfural (HMF) in ionic liquids are provided herein. Glucose is enzymatically converted to fructose by isomerization with glucose isomerase and a borate salt. Conversion of fructose to HMF includes dehydration of fructose using ionic liquids or ionic liquids with an acid catalyst to achieve high yield of HMF.
