晋城15号无烟煤的温和氧化

Mild oxidation of Jincheng No.15 anthracite

摘要: 用钌离子催化氧化法探究了晋城15号无烟煤(J15A)的结构特征,结果表明,J15A富含紧密的芳香性结构.在温和条件下,先用H₂O₂对J15A进行预处理,然后用NaOCl对其氧化从而生成苯多酸.结果表明,H₂O₂预处理可提高NaOCl氧化J15A生成苯多酸的产率,而且该方法可以高收率、高选择性地获取苯多酸化学品.

Abstract: Jincheng No.15 anthracite (J15A) was subjected to ruthenium ion-catalyzed oxidation to characterize its structural feature. The results show that J15A is abundant in peri-condensed aromatic structure. The NaOCl oxidation of J15A promoted by pretreatment with H₂O₂ was conducted under mild conditions to produce benzene polycarboxylic acids (BPCAs). The pretreatment with H₂O₂ is proved to enhance the yields of BPCAs. It is potential to obtain BPCAs in high yield and selectivity by NaOCl oxidation of pretreated J15A with H₂O₂.
