Research Abstract

Lignin was oxidized for 2 min at 200 ℃, the total yield of organic acids was as large as 0.45 g/g-lignin. And an efficient production of pyruvate by the oxidative dehydrogenation of lactate was achieved using a micro flow system based on gas liquid slug flow. Finally, the two-step oxidation process in which valuable chemicals (HMF, organic acids) were recovered with the total yield of as much as 60% was developed.
