Abstract: A two-step 2.5 FDCA integrated production process is described, comprising a first step for generating 5-HMF from streams comprising an aqueous carbohydrate solution wherein sub-critical water works as a catalyst by dehydrating the carbohydrates and generating 5-HMF, and a second step wherein 5-HMF is oxidized into 2.5 FDCA.
