义马萃余煤NaOCl氧化产物的GC／MS分析

GC/MS ANALYSIS OF PRODUCTS FROM OXIDIZED YIMA COAL RESIDUE WITH NaOCl AQUEOUS

用四氢呋喃/二硫化碳混合溶剂对义马煤进行了彻底萃取.在超声波辐射条件下用次氯酸钠水溶液氧化所得的萃余煤,用GC/MS对从反应混合物分离所得的水溶液中的苯可溶物进行了分析.结果表明,在该苯可溶物中共鉴定出16种有机化合物,其中蒽的含量高达85%,其次是棕榈酸、蒽酮和蒽醌,含量各为3%左右,其他化合物的含量都小于1%.

Yima coal was exhaustively extracted with tetrahydrofuran/carbon disulfide mixed solvent. The residue was oxidized with NaOCl aqueous solution under ultrasonic irradiation. Benzene-soluble fraction （BSF） from water-soluble fraction in the reaction mixture was analyzed with GC/MS. The results show that total sixteen organic compounds were identified in the BSF, in which anthracene relative content is as high as 85% and following abundant components are palmitic acid, anthrone and anthraquinone with contents around 3%, whereas contents of others are less than 1%.
