The catalytic efficiency and recyclability of poly(maleic anhydride--1-octadecene) (Od-MA) and poly(maleic anhydride--1-isobutylene) (Bu-MA) were evaluated for use in the development of a metal-free, reusable catalyst for the oxidation of pyridines to pyridine -oxides in the presence of HO. The Od-MA catalyst was easily recovered filtration with recovery yields exceeding 99.8%. The catalyst retained its activity after multiple uses and did not require any treatment for reuse. The Od-MA and HO catalytic system described herein is eco-friendly, operationally simple, and cost-effective; thus, it is industrially applicable. Od-MA and HO could potentially be used in place of percarboxylic acid as an oxidant in a wide range of oxidation reactions.
评估了聚（马来酸酐 - 1 - 十八烯）（Od - MA）和聚（马来酸酐 - 1 - 异丁烯）（Bu - MA）在开发一种无金属、可重复使用催化剂方面的催化效率和可回收性，该催化剂用于在HO存在下将吡啶氧化为吡啶 - 氧化物。通过过滤可轻松回收Od - MA催化剂，回收率超过99.8%。该催化剂在多次使用后仍保留其活性，且无需任何处理即可重复使用。本文所述的Od - MA和HO催化体系环保、操作简单且具有成本效益；因此，它具有工业应用价值。Od - MA和HO有可能在广泛的氧化反应中替代过羧酸作为氧化剂使用。
