One-pot direct conversion of raw straw to furan chemicals simultaneously in a choline chloride-lactic acid/methyl isobutyl ketone biphasic system
The direct and simultaneous production of furan chemicals from raw straw in an efficient deep eutectic solvents/methyl isobutyl ketone (DES/MIBK) biphasic pretreatment system was performed in this study. The deep eutectic solvent was formed by choline chloride (ChCl) as hydrogen-bond acceptor (HBA) and lactic acid (LA) as hydrogen-bond donor (HBD). The effects of straw type and particle size, DES composition (ChCl/LA, molar ratio), reaction time, and temperature on the yield of furan chemicals were investigated. The maximum yield was 25.26%, 21.33%, and 39.21% for 5-hydroxymethylfurfural (HMF) and 5.26%, 9.89%, and 15.48% for 2, 5-furandicarboxaldehyde (DFF) coupled with 5.03%, 5.38% and 8.93% for 2, 5-furandicarboxylic acid (FDCA), respectively, when sweet potato, sorghum, and corn straw were used as the raw biomass. After conversion, the proportion of cellulose as well as its crystallinity index significantly increased. The corn straw was observed as an ideal feedstock with the highest yield of furan chemicals among the tested three raw straws under this conversion system. Results from this study show a simple and operability system without extra catalyst addition for lignocellulosic biomass conversion, which provides new information for direct furan production from raw straw.
