Research on bio-based covalent adaptable networks is popular nowadays in the search for an optimal implementation of thermoset materials and composites in a circular context. Herein, a vanillin derivative is integrated into vitrimers with promising material properties in which the vinylogous urethane associative chemistry has been used as a dynamic...
Research toward bio-based polymers is an expanding field due to environmental concerns. A library of new aliphatic diol-diamide monomers with different chain lengths between the two amido groups was synthesized from sustainable levulinic acid and various linear aliphatic diamines (C 2-C 10). The monomers were prepared by diacylation of the diamines...
Succinic acid (SA) is one of the most important biobuilding blocks in biorefinery. Its production from fermentation of renewable biomass sources is becoming a consolidated alternative that is more sustainable and potentially more economic than the traditional petroleum-based path for SA production. Fermentative production of SA has been successfull...

Two-stage dilute hydrochloric acid (DA)/aqueous ammonia wet oxidation (AWO) pretreatment was used to recover the sugars of corn stover. The morphology characterizations of samples were detected by SEM, BET and SXT. The results showed that DA-AWO process demonstrated a positive effect on sugar recovery compared to AWO-DA. 82.8% of xylan was recovere...

2,5-Furandicarboxylic acid (FDCA), which is usually produced from HMF catalyzed by noble metal catalysts, is an important biobased monomer for the degradable polymer polyethylene furandicarboxylate (PEF). In order to reduce the high costs of starting material and catalysts, a novel approach for the direct conversion of fructose into FDCA was develo...
Selective hydrogenation of biomass-derived 5-hydroxymethylfurfural (HMF) to 2,5-dihydroxymethyl-tetrahydrofuran (DHMTHF) with 96% selectivity and a complete HMF conversion is obtained over palladium catalyst supported on mesoporous graphitic carbon nitride (Pd/mpg-C3N4) under pressured hydrogen atmosphere in aqueous media. The excellent catalytic p...

In this study novel, fully and partially bio-based polyamides containing spiroacetal moieties in the backbone derived from bio-glycerol and bio-ethanol were prepared and characterized. The renewable diamine employed to obtain a series of polyamides was synthesized by means of thiolene click chemistry and therefore contains flexible thioether as wel...
