“…In contrast, higher WPGs appeared in furfurylation of Masson pine and Camphor pine wood, ranging between 20.9% to 35.9% and 37.9% to 44.4% with averages of 25.2% and 39.2%, respectively Esteves et al (2011). treated Pinus pinaster with a 70% FA mixture and found an average WPG of 38% Sejati et al (2017). reported that the WPG of European beech (Fagus sylvatia L.) furfurylated with 50% FA and 5% tartaric acid catalyst was 40.7% for larger samples.…”

“…The authors have proposed a composite acidic catalyst for wood furfurylation in a previous study, which produced furfurylated wood with excellent mechanical and durable properties comparable to the widely used maleic anhydride, with less required FA and a lower cost (Li et al 2015). Recently, Sejati et al (2017) studied furfurylation of beech wood using five different catalysts; in addition to citric acid and maleic anhydride, maleic acid, itaconic acid, and tartaric acid were also studied. They indicated that tartaric acid can be considered as a new promising catalyst to perform wood furfurylation.…”

In this study, 1,3-dimethylol-4,5-dihydroxyethyleneurea (DMDHEU) and furfuryl alcohol (FA) modification catalyzed by acrylic acid were comparatively studied. The effects on physical-mechanical properties and durability against mould of Masson pine and Camphor pine wood were investigated, including weight gain rate (WPG), moisture uptake, equilibrium moisture content (EMC), anti-swelling efficiency (ASE), parallel-to-grain compressive strength (CS), modulus of rupture (MOR), and mould resistance. The wood samples modified with DMDHEU closely retained their original color and texture, whereas the color of furfurylated wood became dark brown and the texture became clearer. The WPG of DMDHEU-treated wood ranged from 17.9% to 29.3%, which was lower than that of furfurylated wood that ranged from 36.7% to 39.3%. The equilibrium moisture content of DMDHEU-modified wood was slightly higher than the untreated wood, while furfurylation decreased the EMC of wood by approximately 50% compared with the untreated wood. The dimensional stability, parallel-to-grain compressive strength, and mildew resistance of Masson pine and Camphor pine improved after both modifications noticeably. It was concluded that acrylic acid can be utilized as a catalyst to perform wood furfurylation and DMDHEU modification.

“…Furfurylated wood has light to dark brown colors, depending on the amount of weight percent gain (WPG) due to the loading of FA resin. Furfuryl alcohol, as well as acid catalyst, buffering agent, and water or ethanol (as solvent) is needed for the wood furfurylation process (Sejati et al 2017).…”

Furfural (F) cannot be easily polymerized like furfuryl alcohol, but it is an aldehyde that can react with urea (U) to make a polymeric network. The possibility of preparing F/U polymer along with an acidic catalyzer (maleic anhydride; M) was evaluated as a means to improve some selected properties of birch (Betula pendula) wood. The F+U/M resin was introduced into the wood with a double treatment technology. The first step involved dilution of F in water and methanol, and the second step was immersion in a U/M aqueous solution. The color of treated wood was darkened after resin curing from brown to a spectrum of black depending on the amount of loaded resin. The 60 to 80% of materials were converted to a non-leachable polymer based on the different formulations. The water absorption and volumetric swelling of the treated samples decreased with an increase in weight percent gain (WPG). The analysis of mechanical strength showed that treatment with F + U/M reduced to some extent the hardness and the impact bending of wood, while modulus of rupture, modulus of elasticity, and compression parallel to the grain with WPG were increased. The exposure of the samples to the accelerated weathering showed noticeable changes in color and roughness.

Effect of Furfurylation on Hierarchical Porous Structure of Poplar Wood

et al. 2020

Some wood properties (such as permeability and acoustic properties) are closely related to its hierarchical porous structure, which is responsible for its potential applications. In this study, the effect of wood impregnation with furfuryl alcohol on its hierarchical porous structure was investigated by microscopy, mercury intrusion porosimetry and nuclear magnetic resonance cryoporometry. Results indicated decreasing lumina diameters and increasing cell wall thickness of various cells after modification. These alterations became serious with enhancing weight percent gain (WPG). Some perforations and pits were also occluded. Compared with those of untreated wood, the porosity and pore volume of two furfurylated woods decreased at most of the pore diameters, which became more remarkable with raising WPG. The majority of pore sizes (diameters of 1000~100,000 nm and 10~80 nm) of macrospores and micro-mesopores of two furfurylated woods were the same as those of untreated wood. This work could offer thorough knowledge of the hierarchical porous structure of impregnatedly modified wood and pore-related properties, thereby providing guidance for subsequent wood processing and value-added applications.
