Preparation of Benzene Polycarboxylic Acids by Oxidation of Coal with NaOCl

Abstract:

Article Preview

Taixi anthracite coal (TXC) was subjected to oxidation with NaOCl aqueous solution under mild conditions. The reaction mixture was extracted with ethoxyethane, followed by esterification with CH2N2, affording esterification products, which were analyzed by GC/MS. A large extent of benzene polycarboxylic acids (BPAs) were obtained in the coal oxidation products. The results showed that oxidation of coals with NaOCl aqueous solution is a useful technique for the high value-added utilization of coals.
