Allyl compound with fully biomass content derived from 2,5-furandicarboxylic acid and eugenol to form high-performance thiol-ene click polymers

A biomass-based monomer with complete biomass content is of utmost importance for achieving sustainability, as it is in accordance with the target of Carbon neutrality and Carbon peak. The findings revealed that FDEU/4SH and FDEU/3SH had similar curing reactivity, and FDEU/4SH displayed improved thermal stability, modulus, and strength, respectively, according to the study. GPa was also the tensile strength of FDEU/4SH, as demonstrated by the tensile modulus of FDEU/4SH, whereas tensile modulus FDEU/4SH was GPa. The key reason behind these outstanding comprehensive properties of FDEU/4SH is its well-designed chemical system, which not only contains 100% of biomass content but also has a rigid crystalline framework and furan ring.

Efficient oxidation of 5-hydroxymethylfurfural to 2,5-furandicarboxylic acid by a two-enzyme system: Combination of a bacterial laccase with catalase.

Many polyesters and polyamides can be produced by using a 2,5-Furandicarboxylic acid. Dioxygen O2 can be produced in a fast and simple manner by using clean H2O2 as the source. Continuous production of O2 is vital, according to the limitations of the O2 diffusion into the inner space of CotA laccase's inner space, and over generation of O2 is not necessary. The bacterial laccase has been shown to produce FDCA by coupling with electron transfer mediator TEMPO and catalase.

Boosting 2,5-Furandicarboxylic acid production via coating carbon over CeO2 in a Pt catalyst

5-hydroxylmethylfurfural production via aerobic oxidation of 5-hydroxylmethylfurfural is promising but it is also difficult due to the catalyst's unsatisfied performance and instability. Na u2082COu2083 is a trademark of the United States CeOu2082 coated carbon supporting Pt catalyst developed herein and used it in the oxidation of HMF. The relationship between CeOu2082 and carbon is suggested, and the role of CeOu2082 and carbon coating is discussed. CeOu2082 is in charge of reducing oxygen storage/release electrons to activate oxygen due to its superior redox capability, while carbon coating is responsible for adsorbing HMF and conducting electrons between CeOu2082's core and carbon surface.

Isosorbide and 2,5-Furandicarboxylic Acid Based (Co)Polyesters: Synthesis, Characterization, and Environmental Degradation.

Polyesters with aliphatic moieties, especially degradability, are a promising family of polyesters, mainly based on renewable resources and with tailored properties, with mainly degradability. They showed improved thermal stability, and the glass transition temperature increased with the amount of FDCA from ca. Following values matching 27% vs. 3% weight loss after 63 days of incubation, respectively, the enzymatic conditions lead to the greatest weight loss in comparison to realistic seawater conditions, with the highest weight loss occurring under simulated seawater conditions.
