2) lignin‐SO3Cu(OTf), and 3) lignin‐IL@NH2 (IL=ionic liquid). These solid materials were then examined in many organic transformations. It was finally found that, compared with its homogeneous counterpart as well as some other solid catalysts that are prepared by using different supports with the same metal or catalytically active species, the lignin‐supported catalysts showed better performance in these reactions
木质素磺酸盐(LS)是有机废物,是造纸过程中亚硫酸盐制浆过程中蒸煮过程的副产品。本文将LS用作固定阳离子物种的阴离子载体材料,然后将其用作某些有机转化中的非均相催化剂。与此策略,制备了三种木质素为载体的催化剂进行,包括1)木质素-SO 3钪(OTF)2,2)木质素-SO 3的Cu(OTF),和3)木质素IL @ NH 2(IL =离子液体)。然后在许多有机转化中检查了这些固体材料。最终发现,与同质对应物以及通过使用具有相同金属或催化活性物种的不同载体制备的其他一些固体催化剂相比,木质素负载的催化剂不仅在以下方面表现出更好的性能:活动,也涉及可回收性。
