用原位红外光谱技术研究Co/SiO_2催化剂上的Kolbel-Engelhardt反应,发现两个吸收峰(585,1390cm~(-1)),与甲酸的吸附比较证实,此两峰为甲酸根在金属钴原子上的吸附所产生的吸收峰,由此我们认为:甲酸根可能是Kolbel-Engelhardt反应的中间体。
The Kolbel-Engelhardt reaction on the Co / SiO 2 catalyst was investigated by in-situ FTIR spectroscopy. Two absorption peaks (585 and 1390 cm -1) were found. The comparison with the formic acid showed that the two peaks were formate Atomic absorption due to the absorption peaks, which we believe: Formate may be Kolbel-Engelhardt reaction intermediates.
