本文对六羰基金属化合物M(CO)_6(M=Cr、Mo、W)在Y型沸石上的热分解进行了程序升温分解质谱和原位红外光谱的研究,并初步讨论了这些六羰基金属在不同碱金属交换沸石上的不同行为,发现M(CO)_6在沸石上热分解能形成相对稳定的中间体“M(CO)_3”。六羰基化合物开始分解的温度以Mo为最低:MoMo>Cr。
In this paper, the thermal decomposition of the metal carbonyl compound M (CO) 6 (M = Cr, Mo, W) on zeolite Y has been investigated by temperature programmed desorption mass spectrometry and in-situ infrared spectroscopy. The effects of these metal hexacarbonyls Different behavior on different alkali metal exchanged zeolites, it was found that M (CO) _6 was thermally decomposed on zeolite to form relatively stable intermediate “M (CO) _3”. The temperature at which the hexacarbonyl compound begins to decompose is Mo: Cr Mo> Cr.
