“…The ring protons emerge due to the asymmetry as three groups of signals in a region 6.57–7.67 ppm (3H). Similar 1 H NMR signals were previously revealed by Ismiyarto et al 33 for furfural prepared from hydrolysis of dried biomass of water hyacinth ( Eichornia crassipes ). Likewise, similar peaks were depicted for the standard furfural sample provided by Sigma.…”

“…Bands at 3133, 2853, 2808, and 1367 cm −1 are characteristic of aldehyde groups. 33 The C–O stretching vibration is ascribed to peaks located at 1159 and 1222 cm −1 . The aromatic C C bending and C–H out-plane bending vibration are ascribed to peaks from 1565 to 1464 cm −1 and 927 to 841 cm −1 , respectively.…”

“…The gas composition in the headspace of the cell was analyzed using in‐line gas chromatography analysis every 20 minutes until the completion of the reaction. Liquid products were analyzed by 1 H NMR (Bruker 300 MHz) of crude reaction mixtures combined with an internal standard (1,2,4,5‐tetrachlorobenzene) and compared against the previously reported NMR data furfural and hydrofuroin [18,45] …”

Electrochemical Hydrodimerization of Furfural in Organic Media as an Efficient Route to Jet Fuel Precursor

Upgrading biomass-derived compounds to value-added products, especially fuels, represents a green route alternative to fossil fuels energy sources. Here, we report an efficient electrosynthesis of a jet fuel precursor hydrofuroin from furfural, which is one of the most valuable compounds derived from biomass. Despite the high value of this process, few studies have been focused on the development of synthetic strategies for electrocatalytic hydrodimerization of furfural to hydrofuroin. In this work, we systematically examine how operating parameters, including the electrolyte, applied potential, furfural concentration, and catalyst nature affect the efficiency of hydrofuroin electrosynthesis in organic media. We show that under the optimized conditions, the electrosynthesis can be carried out in a simple undivided cell with a high faradaic efficiency (up to 74 %) and an excellent hydrofuroin yield (up to 100 %).

“…For monomer in Fig. 3, a, absorption band at 3130 cm 1 was due to aromatic C-H, peaks about 2845 and 2812 cm 1 are attributed to the C-H aldehyde, peak at 1670 cm 1 was related to C=O aldehyde, and the peaks between 1500 cm 1 and 1000 cm 1 were due to C=C in furan ring and C-H out of plane [17]. In Figure 3, b, FT/IR spectra of polymer have same peaks as in the spectra of monomer, but peak at 1670 cm 1 (C=O aldehyde) is weakened due to consumption of aldehyde by polymerization.…”

In this paper, polyfurfural is synthesized by hydrochloric acid as catalyst in ethanol. The resulting polymer is characterized by FT/IR, EDS and XPS to determine the polymer structure. By SEM, the morphology of resulting polymer is studied. As found, the polymer consists of globule particles, which clump together and form clusters with average size of about 700 nm. Globule particles are composed of small spherical particles with an average size of 18.6 nm. Polymer thin film is fabricated by anchoring on glass; thin film has rough surface (Rms2.120.3 nm) and nanoparticles size of 17.8 nm. Based on x-ray diffraction, the crystallization ratio and the nanocrystals' size (7.42 nm) are calculated. A new method for the determining nanoparticle size from x-ray diffraction data is proposed. The particle size is of 16.18 nm that is less than the size specified by SEM or AFM.У даній роботі поліфурфурол синтезується соляною кислотою як каталізатором в етанолі. Одержаний полімер характеризується інфрачервоною спектроскопією на основі перетвору Фур'є, енергодисперсійною рентґенівською спектроскопією та рентґенівською фотоелектронною
