Oxidation of Huolinguole Lignite with NaOCl

摘要

Huolinguole lignite (HL) was oxidized with aqueous NaOCl solution under mild conditions. The oxidation products were analyzed by GC/MS. In total 111 products from the HL oxidation were detected, most of which were benzene polycarboxylic acids and short-chain alkanoic acids, while a predominant chlorinated compounds such as trichloromethane, dichloroacetic acid, trichloroacetic acid were also identified. These results indicate that oxidation of coals with aqueous NaOCl solution may be a promising method for high value-added utilization of coals.
