%X Two coals were oxidized with aqueous NaOCl solution under mild conditions.The reaction mixture acidified was sequentially extracted with ethoxyethane,CS2,petroleum ether,acetic ester and benzene,followed esterification by CH2N2 and analysis with GC/MS.The results show that chloro-substituted compounds,aliphatic acids and aromatic polycarboxylic acids are main products.The oxidative product was sequentially extracted with different polar solvents and achieved a simple group separation.Effective separation and analysis of oxidation products of coal in aqueous NaOCl solution,established by the study,provides a feasible method for high value-added use of coal.
