Abstract:
A new process for the production of furfuryl alcohol from corncob was constructed by using deep eutectic solvents and whole cell catalysis in this paper. Firstly, the corncob was treated with deep eutectic solvents to convert the xylan into furfural, and then the pretreated corncob residue was enzymatically hydrolyzed to obtain a glucose-rich enzymatic hydrolysate, which was used to provide NADH for Bacillus coagulans NL01 during the process of furfural reduction. The furfural yield could reach 46% using the selected choline chloride-oxalic acid as catalysts and corncob as substrate under the optimized catalytic condition at 120 °C for 30 min. The final furfuryl alcohol yield of 20.7% was achieved with corncob as substrate. Moreover, this catalytic system realized the recycling of deep eutectic solvents three times, the high-value production of furfuryl alcohol, and the comprehensive utilization of corncob.

The acid-catalyzed addition of water to the double bond of alkenes is a large-scale industrial method used to synthesize low-molecular-weight alcohols. An acidic atmosphere is required to allow the hydrogen in the water molecule to act as an electrophile and attack the double bond in an alkene. The addition of a proton to the double bond creates a carbocation intermediate. The proton preferentially bonds to the less substituted end of the double bond to create a more stable carbocation...
