Title: Highly Efficient Conversion of Biomass-Derived Glycolide to Ethylene Glycol Over CuO in Water
Abstract: The efficient conversion of biomass-derived glycolide into ethylene glycol over CuO in water was investigated. After the optimized reaction conditions, the reaction of glycolide was carried out with 25 mmol Zn and 6 mmol CuO with 25% water filling at 250 °C for 150 min, which yielded the desired ethylene glycol at 94% yield. In this work, water acted not only as an excellent environmentally benign reaction medium but also as a hydrogen source. A possible reaction pathway for the in situ hydrogenation of bio-based glycolide into ethylene glycol was proposed. The study provided a green process for the efficient formation of ethylene glycol from biomass-derived glycolide without the use of gaseous hydrogen.
