Abstract

Anion-exchange resins modified with metal-porphine (M-Pr) have been investigated to develop a solid catalyst in the oxidative reaction of phenols by O2 in air. Co-Pr, which is easily prepared and separable from the reaction mixture, has been proved to accelerate the oxidative reaction of phenols such as 3,5-di-tertbutyl-4-hydroxyanisole. The resulting main oxidative products were identified to be quinones by using the GC-MS method.

摘要

已对用金属卟啉（M-Pr）改性的阴离子交换树脂进行了研究，以开发一种用于空气中O₂氧化酚类反应的固体催化剂。已证明易于制备且可从反应混合物中分离的Co-Pr能加速3,5-二叔丁基-4-羟基苯甲醚等酚类的氧化反应。通过气相色谱-质谱联用（GC-MS）方法确定所得的主要氧化产物为醌类。
