Abstract
运用循环伏安和现场fTIr反射光谱研究了碱性介质中乙二醇在铂电极上的吸附和氧化行为。结果表明,乙二醇的氧化与溶液酸碱性密切相关,除成功地检测到CH_2OH-COO--、--OOC-COO--等中间产物及CO_2、等最终产物外,还发现乙二醇氧化过程中有乙烯酮中间体生成。
 
The electrooxidation of ethylene glycol (EG) in alkaline media has been investigated with in situ FTIR spectroscopy and cyclic voltammetry.The main products such as CO_2 and were detected clearly.Besides CH_2OHCOO ̄- and  ̄-OOC-COO- species, a new intermediate, (with its IR absorption band at 2027cm ̄(-1) in 0.1 mol/L and at 2036 cm ̄(-1) in 0.05 mol/L NaOH solution), was determined and a possible mechanism to Form this intermediate was proposed.
