One-Pot Synthesis of 2,5-Furandicarboxylic Acid from 2-Furoic Acid by a Pd-catalyzed Bromination-Hydroxycarbonylation Tandem Reaction in Acetate Buffer.

For the first time using a Pd-catalyzed bromination-hydroxycarbonylation tandem reaction in HOAc-NaOAc buffer, a one-pot synthesis of 2,5-furfurylic acid from 2-furoic acid yielded a 57 percent. Hence, Br 2 should be consumed in the first bromination step as fully as possible in this practical one-pot synthesis, and CO is introduced after the first bromination step is complete.

Efficient Production of Adipic Acid by a Two-Step Catalytic Reaction of Biomass-Derived 2,5-Furandicarboxylic Acid.

A promising but difficult reaction to make adipic acid from 2,5-furan dicarboxylic acid is an efficient catalytic ring-opening with hydrogenation. Fortunately, Ru/Al 2 O 3 has been shown to be a more cost-effective catalyst for hydrogenation and hydrogenolysis of FDCA, resulting in THFDCA and 2-hydroxyadipic acid, respectively, where ruthenium is more cost-effective than well-known palladium or rhodium hydrogenation catalysts. The alumina phase positively influences Ru nanoparticles and supports' interaction, resulting in a mixture with high dispersion and small size of Ru NPs, which in turn are responsible for the high conversion of FDCA.

Production of the 2,5-Furandicarboxylic Acid Bio-Monomer From 5-Hydroxymethylfurfural Over a Molybdenum-Vanadium Oxide Catalyst.

Durandicarboxylic acid, a key bio-monomer that may be able to convert degradable polyesters from terephthalic acid. In the last decades, efficient selective oxidation of biomass-based 5-hydroxymethylfurfural to FDCA has been a significant yet challenging task. A novel molybdenum-vanadium oxide catalyst was developed by a simple procedure and showed excellent catalytic capacity for converting HMF to FDCA in this research. HMF oxidation's estimated activation energies were obtained after fitting experimental results with the first-order kinetics equation.

Enabling Efficient Aerobic 5-Hydroxymethylfurfural Oxidation to 2,5-Furandicarboxylic Acid in Water by Interfacial Engineering Reinforced Cu-Mn Oxides Hollow Nanofiber.

Mn 2 O 3 and Cu 1. 4 Mn 1. 6 O 4 was constructed by electrospinning and a customised thermal treatment technique, herein. The tuning thermal treatment resulted in tailored Cu I sites and surface oxygen species of the catalyst, providing improved oxygen vacancies for increased oxygen adsorption, while the concomitant increased lattice oxygen activity in the assembled composite catalyst ensured the increased catalytic oxidation capability. In the best catalyst, the optimal ratio of oxygen vacancy and lattice oxygen in the composite catalyst was found, which was helpful to accelerate the reaction cycle.
