“…Liu et al [145,146] modified sugarcane bagasse cellulose by succinoylation catalyzed with I 2 in butyl-3-methylimidazolium chloride [C 4 mim]Cl and DMSO system. It was found that, at 110°C and 60 min, the succinoylation efficiency increased in the following order 0.74, 0.92, 1.13, 1.25, 1.29, and 1.30, for I 2 increase of 2, 4, 6, 8, 10, and 15%, respectively.…”

Not only does the molecular iodine play a leading role in organic synthesis but also in the polymer synthesis. Different kinds of polymerization initiated by molecular iodine are herein screened: cationic polymerization, radical polymerization, living/controlled radical polymerization (LCRP) such as reverse iodine transfer polymerization, polycondensation, and ring-opening polymerization (ROP). Also, the functionalization of polymers using molecular iodine, such as the acetylation of polysaccharides (cellulose, starch), and the use of iodine-polymer complex in organic synthesis are also discussed. Numerous natural and synthetic polymers are prone to make complexes with molecular iodine, and one feature of such complexes is their propensity as polymer-supported reagent and catalysts in many organic syntheses.

“…The spectrum shows also (-C-H) stretching vibration at peak with wavenumber of 2,897 cm -1 . Finally, the absorption band at 3,347 cm -1 is due to the stretching frequency of the (-OH) group as well as the intra-and inter-molecular hydrogen bonds within cellulose macromolecules [39,40].…”

“…As reported in literature, peaks appearing at wavelength of 1,620 cm 1 and 1,423 cm -1 represented specific functions in CMC [31,[43][44][45][46]. The intensity of the peak at 1,025 cm -1 for C-O-C stretching slightly decreased due to the degradation of the cellulose simple during the modification's process [40]. The infrared spectra of modified vine stem (CMCNa-VS-1 and CMCNa-VS-2) is given in Fig.…”

Synthesis and Characterization of Carboxymethyl Cellulose from Tunisian Vine Stem: Study of Water Absorption and Retention Capacities

et al. 2014

The aim of this work was to study the effect of the degree of substitution (DS) and the purity of sodium carboxymethyl cellulose (CMCNa) prepared from Tunisian vine stem on the absorption and retention of water. Vine stem was first delignified using souda-anthraquione, then bleached and finally chemically modified, in order to synthesize different CMCNa derivatives. The carboxymethylation reaction was carried out in presence of NaOH (40 %) and monochloroacetic acid (ClCH 2 COOH), in n-butanol as a reaction solvent. The obtained CMCNa derivatives were characterized using different tools such as the DS, Fourier transforms IR techniques, CP-MAS 13 C-NMR, the exchange capacity as well as the determination of modification reaction yield. The performance of the prepared derivatives in term of absorption capacities and retention capacities was established. The performance of CMCNa derivatives was compared with that achieved by commercial counterparts and it was concluded that the prepared ones exerted higher efficiency.

“…The band at 1375 cm −1 was associated with O-H bending. The peak at 1158 cm −1 represented C-O antisymmetric bridge stretching (Liu et al 2011). The new band at 1732 cm −1 in the SMC spectrum illustrated that an esterification reaction occurred between the cotton linter and SA.…”

A new chelating material from mercerized cotton linter was prepared by a reaction with succinic anhydride in the presence of toluene/triethylamine and a 4-dimethylaminopyridine catalyst, followed by reacting with Fe(III) to obtain the final product. The materials were characterized by Fourier transform infrared spectrometry, scanning electron microscopy, and energy dispersive spectrometer; the adsorption of chromium(VI) from an aqueous solution was examined. The Langmuir isotherm accurately fit the experimental data, and the calculated adsorption ability of Fe(III)-loaded adsorbent for chromium(VI) was 11.1 mg/g. The adsorption process followed a pseudo-second-order kinetic model.
