摘要： 为探究芦苇基醋酸纤维素制备的可行性,在传统乙酰化催化的基础上,以醋酸为溶剂、醋酸酐为酰化剂,并首次以浓硫酸和La3+为协同催化剂,构建芦苇基溶解浆粕乙酰化反应的高效催化体系。借助红外光谱、扫描电镜和X射线衍射技术,系统地研究了醋酸酐用量、乙酰化反应时间、乙酰化反应温度及La3+添加量对乙酰化产物取代度和结晶性能的影响。结果表明:反应时间为2 h,反应温度为70 ℃,芦苇基溶解浆粕、乙酸、乙酸酐的固液比为2∶100∶18时,在活化过程中加入硫酸和硝酸镧混合催化剂,当硝酸镧添加量与芦苇基溶解浆粕质量比为22.5%时,醋酸纤维素的取代度达到了最大值2.85。进一步运用密度泛函理论(DFT)对La3+协同强化催化芦苇基溶解浆粕乙酰化反应机制进行理论分析,计算结果证实随着La3+加入,因其独特的电子结构和强配位能力,La3+和醋酸酐分子相互作用生成中间体络合物[La(Ac2O)2]3+,络合物中的电子密度重新分布,极大降低了硫酸电离出的电子给予体HSO−4与之反应生成乙酰基磺酸的能垒,继而乙酰基磺酸与芦苇基溶解浆中的纤维素发生乙酰化反应。

Abstract:

Objective Aiming at the high value utilization of reed-based pulp, obtained from the rich reed resources in Dongting Lake area, this research explores the feasibility for the preparation of reed-based cellulose acetate under an efficient catalytic system and tests and analyzes the microstructure and performance of the thus-obtained reed-based cellulose acetate. Meanwhile, the co-catalytic mechanism of La3+ in the process of acetylation was studied in detail.

Method The reed-based cellulose acetate was prepared by low temperature acetylation., where acetic acid is used as solvent, acetic anhydride as acylating agent, concentrated sulfuric acid and La3+ as co-catalyst for the first time. The effects of acetic anhydride dosage, acetylation time, acetylation temperature and the addition amount of La3+ on the degree of substitution and crystallinity of the acetylation products were systematically studied. The whiteness and polymerization degree of the prepared reed-based cellulose acetate were evaluated. The degree of substitution, crystallization property, morphology and structure of the thus-obtained sample were scrutinized, measured and analyzed. The density functional theory was used to analyze the synergistic catalytic mechanism of La3+ during the acetylation of dissolved reed pulp.

Results Under the conditions that the reaction time was 2 h, the reaction temperature was 70 ℃, and the solid-liquid ratio of acetic anhydride to acetic anhydride was 2∶100∶18, the corresponding acetylation products showed obvious acetyl functional group characteristic absorption peaks around 1 750, 1 380 and 1 235 cm-1, regardless of whether La3+ was added. However, it is worth noting that when the mass ratio of lanthanum nitrate to reed-based pulp was 22.5%, the acetyl functional group characteristics in the corresponding FT-IR spectrum illustrated obvious blue shift, which was due to the fact that the hydroxyl group in the dissolved pulp was replaced by a larger acetyl group during the acetylation reaction, resulting in breakage of the intermolecular and intramolecular hydrogen bond of the product. The maximum degree of substitution was 2.85, the whiteness of the thus-obtained cellulose acetate was 87.45 and the average degree of polymerization was 171. Scanning electron microscope images of the acetylation products under different conditions showed porous structures. The characteristic (210), (310), (021) and (012) crystal planes representing cellulose acetate showed diffraction peaks of acetylated products after the addition of different amounts of lanthanum nitrate. When the ratio of lanthanum nitrate to reed pulp was 22.5%, the characteristic diffraction peak was the strongest. In addition to the slight increase of grain size corresponding to (021) crystal plane, the grain size corresponding to other crystal planes was decreased significantly, indicating that under the synergistic catalysis of an appropriate amount of La3+, the acetylation reaction of dissolved reed pulp was easier to penetrate into the crystallization zone, so that the hydrogen bond in the fiber chain was continuously opened and then broken. The DFT calculation results supported and confirmed that with the addition of La3+, due to its unique electronic structure and coordination ability, La3+ and acetic anhydride molecules interact to form an intermediate complex [La(Ac2O)2]3+, and the electron density in the complex is redistributed. This greatly reduces the energy barrier for the ionized electron donor HSO−4 of sulfuric acid to react with it to form acetyl sulfuric acid, which in turn acetylates with cellulose in the dissolved reed pulp.

Conclusion The reed-based cellulose acetate was successfully prepared by low temperature acetylation by using concentrated sulfuric acid and La3+ as co-catalyst. Density functional theory (DFT) analysis shows that the addition of La3+ can effectively improve the catalytic efficiency of acetylation. The successful preparation of reed-based cellulose acetate will provide a foundation for high-value utilization of natural renewable cellulose resources, which has important academic significance and obvious social and economic value.
