An Integrated Approach for the Production and Isolation of 5-Hydroxymethylfurfural from Carbohydrates

Crystal clear: An integrated, simple, efficient, reusable, and scalable methodology for the dehydration of fructose to HMF offers outstanding yields and high purities. The method uses wet tetraethylammonium bromide as reaction medium, allowing the isolation of HMF by crystallization from the reaction medium. The process is also feasible starting from other carbohydrates, such as glucose, sucrose, or inulin.
