Abstract This study investigated the conversion of sugars into furan derivatives, specifically 2,5-dimethylfuran, through catalytic processes using bibliographic analysis. This method evaluates scientific outcomes and impact within a specific field by analyzing data such as publication trends, references, collaborative models, leading authors, and institutions. The study utilized data from the reliable Scopus database and conducted analysis using the visualization of similarity (VOS) viewer program to gain in-depth insights into the current state of research on this topic. The findings revealed that “5 hydroxymethyl furfural” was the most used keyword, followed by “biomass” and “catalysis.” The research More >

Abstract Sugarcane bagasse is an agro-waste that could replace timber resources for the production of bio-composites. Composite boards such as particleboard offer an issue for the use and recycling of poor quality timber, and these engineered products can overcome some solid wood limitations such as heterogeneity and dimension. Bagasse offers an alternative to wood chips for particleboard production but present some disadvantages as well, such as poor physico-mechanical properties. To address these issues, bagasse fibers were treated with an innovative natural resin formulated with tannin and furfural. Impregnated particles with different concentrations of resin (5%, 10%,… More > Graphic Abstract

Abstract Renewable resources based polymers provides a sustainable alternative to petroleum derived polymeric materials. As a part of our series on synthesis of vanillin based renewable polymers, we report the synthesis of poly(hydrovanilloin-furfural) [poly(HVL-Fur)] and poly(hydrovanilloin–5-hydromethylfurfural) [poly(HVL-5-HMF)]. Vanillin was dimerized to a mixtures of meso/DL-hydrovanilloins with 94% meso product by electrochemical reductive coupling in aqueous sodium hydroxide using lead electrodes in quantitative yield. Then sodium hydroxide catalyzed condensation of hydrovanilloin with furfural in water at 80°C for 72 h was used to synthesize poly(HVL-Fur) with Mw = 8600 g mol⁻¹, PDI = 1.28 in 78% yield. Similarly, condensation of hydrovanilloin More > Graphic Abstract

Abstract Hemicellulose and lignin are not reasonably utilized during the dissolved pulp preparation process. This work aimed to propose a process for the co-production of dissolving pulp, furfural, and lignin from eucalyptus. High-grade dissolving pulp was prepared from eucalyptus using a combination of extremely low acid (ELA) pretreatment, Kraft cooking, and elementary chlorine-free (ECF) bleaching. The obtained pre-hydrolysate was catalytic conversion into furfural in a biphasic system, and lignin during Kraft cooking and ECF was recovered. The process condition was discussed as well as the mass flow direction. The results showed that ELA pretreatment could effectively… More >

Abstract An effect of phase compositions (rutile, Rut and anatase, Ant) of TiO₂ supports on the selective hydrogenation of furfural to furfuryl alcohol was investigated. The 15%wt Ni/TiO₂ catalysts were prepared by incipient impregnation method. The result showed that Ni supported on anatase-rutile mixed phase TiO₂ (91% Rut and 9% Ant, A2) provided the highest furfuryl alcohol yield at 43.8% due to the relatively strong Ni-TiO₂ interaction, its appropriate crystallite sizes, and high average pore sizes. Furthermore, the effect of cobalt as a promoter on Ni/ TiO₂-A2 catalysts was studied. The result showed that the Ni-Co/TiO₂-A2 catalysts exhibited poorer More > Graphic Abstract

Abstract The main principles of the technological realisation of the furfural obtaining process have been formulated by Ricard [1]. Based on his recommendations, all investigators proceeded from the assumption that the depolymerisation of pentosans and the dehydration of pentoses in the one-step production of furfural from raw plant material must be accelerated with diluted catalyst solutions. According to this theory, uniform impregnation of the raw material with a catalyst solution is considered necessary. The reduction in the amount of the catalyst solution down to 30–40% of the mass of the dry raw material, suggested by Miner… More >

Abstract Raman (resonance Raman, FT-Raman), IR and UV-visible spectroscopy and quantum chemistry calculations were used to investigate the photodissociation dynamics of furfural in S₂ state. The resonance Raman(RR) spectra indicate that the photorelaxation dynamics for the S₀→S₂ excited state is predominantly along nine motions: C=O stretch ν₅ (1667 cm^-1), ring C=C antisymmetric stretch ν₆ (1570 cm^-1), ring C=C symmetric stretch ν₇ (1472 cm^-1), C2-O6-C5 symmetric stretch/C1-H8 rock in plane ν₈ (1389 cm^-1), C3-C4 stretch/ C1-H8 rock in plane ν₉ (1370 cm^-1), C5-O6 stretch in plane ν₁₂ (1154 cm^-1), ring breath ν₁₃ (1077 cm^-1), C3-C4 stretch ν₁₄ (1020 cm^-1), C3-C2-O6 symmetric stretch ν₁₆ (928 cm^-1 ).

Abstract An adhesive based on the reaction of a very fast reacting procyanidin-type condensed tannin, namely purified pine bark tannin, with a biosourced nontoxic and nonvolatile aldehyde derived from the pulp and paper industry, namely hydroxymethylfurfural (HMF), was shown to almost satisfy the relevant standards for bonding wood particleboard. The conditions of pH used are determinant for the result. The oligomers obtained by the reaction and their distribution have been determined by matrix-assisted laser ionization desorption time-of-flight (MALDI-TOF) mass spectrometry. Of the two reactive groups of hydroxymethylfurfural capable of reacting, the furanic aldehyde one and the More >
