  磁性二氧化硅负载布朗斯台德酸性离子液体的制备用于木质素解聚为芳香族单体

  摘要：

  木质素是自然界中最丰富的芳烃可再生资源，被公认为化石燃料和化学品的替代品。在此，我们提出了一种利用磁性二氧化硅负载的布朗斯台德酸性离子液体（BAIL-Fe 3 O 4 @ SiO 2 ）通过木质素解聚获得芳香族单体的有效方法，与传统的木质素解聚相比，该方法具有更高的催化活性和更容易的分离性能。离子液体。制备的BAIL (30 wt%)–Fe 3 O 4 @ SiO 2催化剂具有磁性、介孔、热稳定性和核壳结构，直径为500-600 nm，BET表面积为185.7 m 2 g -1, 孔径为 4.362 nm。结果表明，在 40 wt% 的 BAIL (30 wt%)–Fe 3 O 4 @ SiO 2存在下，在 160 °C 处理 3 h，木质素的转化率显着提高到 54.0% 和 33.0% 的芳香族单体收率。被收购。在 BAIL (30 wt%) 上来自木质素解聚的乙醇可溶液体产品中–Fe 3

  Four novel Brønsted acidic ionic liquids with two different acid sites on the imidazolium cations were synthesised and employed as catalysts and solvents for the ring-opening of cyclic anhydrides to synthesise half-esters. The results showed that these novel Brønsted acidic ionic liquids were efficient and recyclable. Good yields, short reaction times and mild reaction conditions were achieved.

  Imidazolium-silica heterogeneous catalyst (SG-[(CH2)(3)SO3H-HIM]HSO4) was prepared by immobilization of acidic ionic liquid 1-(propyl-3-sulfonate) imidazolium hydrosulfate ([(CH2)(3)SO3H-HIM]HSO4) on silica-gel using tetraethoxysilane (TEOS) as silica source in this study. The properties of the samples were characterized by FT-IR, SEM and TG/DSC. The results suggested that [(CH2)(3)SO3H-HIM]HSO4 had been successfully immobilized on the surface of silica-gel and the immobilized ionic liquid catalyst SG-[(CH2)(3)SO3H-HIM]HSO4 had good thermal stability. The original smooth surface of silica-gel was covered with [(CH2)(3)SO3H-HIM]HSO4 and a rough surface of SG-[(CH2)(3)SO3H-HIM]HSO4 was formed, but the size of particles had no obvious change. Moreover, SG-[(CH2)(3)SO3H-HIM]HSO4 exhibited high catalytic activity for a series of acetalization and could be recovered easily. After reused for 10 times in the synthesis of benzaldehyde ethanediol acetal, the catalyst could still give satisfactory catalytic activity. (C) 2011 Elsevier B.V. All rights reserved.

  Polystyrene (PS)-supported 1-(propyl-3-sulfonate) imidazolium hydrosulfate acidic ionic liquid (PS-CH2-[SO3H-pIM][HSO4]) catalyst was prepared by supporting the ionic liquid onto highly cross-linked chloromethylated polystyrene (PS-CH2Cl). FT-IR, SEM and TG-DSC were employed to characterize the structure and property of the catalyst. Results suggested that acidic ionic liquid was supported onto the surface of PS-CH2Cl by covalent bond. The original rough surface of PS-CH2Cl was covered with acidic ionic liquid, forming a compact and thin surface layer, and its size had no obvious change. Moreover, the PS-CH2-[SO3H-pIM][HSO4] catalyst showed a better thermal stability than that of PS-CH2Cl support. It also exhibited high catalytic activity for a series of esterifications. After the catalyst was reused for 13 times in the synthesis of n-butyl acetate, the yield only decreased 7.3%. A reaction mechanism of esterification over this new catalyst was proposed as well.
