Mechanism / Method Highlights

  • Metal cations form hydrated ions that release H+ through hydrolysis and also act as Lewis acids; Fe3+ and Cu2+ show strong acidity because of high charge density and small ionic radius. The 2-MTHF/H2O biphasic system extracts in-situ furfural into the organic phase, suppressing side reactions with xylose and improving selectivity.

Application Value

  • The GAS-800 microwave reactor provides rapid uniform heating at 10 °C/min and completes prehydrolysis within 20 min.
