“…The band at 1642 cm -1 is associated with adsorbed water in cellulose and probably some hemicelluloses [17,[37][38]. The bands at 1430, 1370, 1335 and 1320 cm -1 are attributed to CH2 symmetric bending, CH bending, in-plane OH bending, CH2 rocking vibration, respectively [17,[38][39], and the bands at 1162, 1111, 1057, 1033, 898 cm -1 are assigned to asymmetric C-O-C bridge stretching, anhydroglucose ring asymmetric stretching, C-O stretching, in-plane C-H deformation and C-H deformation of cellulose, respectively [17,[38][39][40][41]. The total crystalline index (TCI), lateral order index (LOI), hydrogen bond energy (EH), and hydrogen bond intensity (HBI) were calculated from the spectra obtained from FTIR spectroscopy.…”

“…The band at 1642 cm -1 is associated with adsorbed water in cellulose 19,22,23 . The bands at 1430, 1370, 1335 and 1320 cm -1 are attributed to CH 2 symmetric bending, CH bending, OH in plane bending, CH 2 rocking vibration, respectively [21][22][23] , and the bands at 1162, 1111, 1057, 1033, 898 cm -1 are assigned to asymmetric C-O-C bridge stretching, the anhydroglucose ring asymmetric stretching, C-O stretching, C-H in plane deformation, C-H deformation of cellulose, respectively [21][22][23][24]26 . On the other hand, the peaks for xylan from hemicelluloses are derived from molecular vibrations in the uronic acids at 1730 and 1600 cm -1 [28] .…”

“…Several techniques as X-ray diffraction and FTIR spectroscopy were used to evaluate the wood and cellulose crystallinity 5,7,8,9,10,12 . However, FTIR spectroscopy has been used as a simple technique for obtaining rapid information about the structure of cellulose and chemical changes taking place in cellulose due to various treatments 10,21,22,[25][26][27] . As mentioned earlier, the crystalline structure of cellulose affects the physical, mechanical and thermal properties of cellulose fibers.…”

In this study Eucalyptus grandis (CEG) and Pinus taeda (CPT) cellulose fibers obtained from kraft and sulfite pulping process, respectively, were characterized using Fourier transform infrared (FTIR) spectroscopy and thermogravimetry (TGA). The degradation kinetic parameters were determined by TGA using Coats and Redfern method. FTIR results showed that CPT presented a more ordered structure with higher crystallinity than CEG. Thermogravimetric results showed that CPT had a higher thermal stability than CEG. The kinetic results revel that for CEG the degradation mechanism occurs mainly by random nucleation, although phase boundary controlled reactions also occurs while for CPT the degradation process is more related with phase boundary controlled reactions. Results demonstrated that differences between thermal stability and degradation mechanisms might be associated with differences in the cellulose crystalline structure probably caused by different pulping processes used for obtaining the cellulose fibers.

“…The changes in the diffractograms of the TW were analyzed in order to determine the crystallinity index (CI); these values are reported in Table 3. The CIXRD value of the TW at pH 8 was higher, followed by the TW at pH 9, pH 10, pH 11, and raw wood, respectively (Chen et al 2010). The resulting values are due to the removal of wax, hemicellulose, and pectin from wood, and the decrease in amorphous movement of the wood cell wall by polymerized 4-methyl catechol at lower pH levels (Howell et al 2009;Agubra et al 2013).…”

“…This peak was due to the conversion of the aromatic ring of 4-methylcatechol to aliphatic alkene (Jha and Halada 2011). The absorbance at 1510 cm -1 corresponded to the benzene ring stretching vibration in lignin (Chen et al 2010).…”

Four types of treated wood (TW) were prepared by the impregnation of solid wood each with a solution of 4-methyl catechol at pH 8, a solution of 4-methyl catechol at pH 9, a solution of 4-methyl catechol at pH 10, and a solution of 4-methyl catechol at pH 11. These TW were characterized by Fourier transform infrared spectroscopic, X-ray diffraction (XRD), scanning electron microscopic, 3-point bending, freefree-vibration, and thermo-gravimetric analysis. FT-IR result showed that TW had more than one carbonyl absorbance band between 1745 and 1690 cm -1 , while raw wood had only one carbonyl absorbance band in this regard. TW at pH levels of eight and nine showed higher crystallinity index (CIXRD) than that of raw wood. The SEM micrograph of TW at pH 8 had a smoother surface compared with other treated wood and raw wood. The modulus of elasticity (MOE), and modulus of rupture (MOR) of TW at pH 8 and pH 9 significantly increased. The raw wood exhibited a higher water uptake compared with the TW. The TGA results showed that TW were thermally less stable between 267 and 400 °C than raw wood.
