概要	Environment-friendly hydrothermal systems have been explored as efficient methods for converting cellulose-containing materials (such as cotton and wood waste) into HMF. We developed a hydrothermal flow process for producing HMF from cotton-containing waste using hydrothermal solutions, successfully decreasing the running temperature to 225 °C using citric acid. In this study, we demonstrated a practical purification method to obtain HMF from an HMF-containing product solution. The proposed method uses classical, simple, and well-known materials such as ion-exchange resins, activated carbon, and ethanol. The conditions for the selective removal of BBPs against HMF from hydrothermally treated products using ion-exchange resins were optimized. HMF was purified within 60 min using an anion-exchange resin, the adsorption of HMF using activated carbon was completed within 30 min, and the desorption using ethanol was performed within 10 min.
