pb/dmf-etoh体系中煤炭的电化学加氢：利用溶液萃取法研究煤炭在电解过程中的结构变化
, PP. 262-269
Keywords: 煤炭,电化学还原,氢化,铅电极,有机电解液
Abstract:
？以dmf（氮，氮-二甲基甲酰胺）/乙醇为电解质溶液，研究了煤炭在铅电极表面的电化学加氢作用。利用有机溶剂萃取得到电解产物，并对其进行表征。通过元素分析分析发现，电解产物h/c原子比有了显著提高，体现出该电解体系较高的加氢效率。红外光谱显示，电解过程中c=o键和芳环结构得到了有效还原。煤分子结构中的桥键，如c-o-c，也发生了裂解反应。通过1h-nmr分析，进一步印证了煤电解过程中的结构变化，并提出了可能的反应机理。
