中文摘要：
两种煤于温和条件下在次氯酸钠水溶液中进行降解,所得水溶液经酸化后,水溶物依次用乙醚、CS2、石油醚、乙酸乙酯和苯进行分级萃取,萃取物经重氮甲烷酯化后用GC/MS分析。结果发现氯代物、脂肪酸和芳酸是煤的NaOCl水溶液降解的典型化合物,不同极性溶剂分级萃取可以实现产物的初步族组分分离。通过该研究建立煤的次氯酸钠氧化反应混合物有效分离和分析的方法,为煤的高附加值利用提供有效的途径。
英文摘要：
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.
