Mild oxidation of Jincheng No.15 anthracite

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.
