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.
