摘要: 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.

Abstract: In this paper, thermal decomposition of metal hexacarbonyls M(CO)6(M = Cr, Mo, W) in zeolites Y has been studied by infrared spectroscopy (IR) and temperature programmed decomposition-mass spectra (TPDE-MS), and properties of metal hexacarbonyls absorbed in zeolites MY (M = Na, K, Rb, Cs) have also been discussed. It is found that stable intermediates "M(CO)3" are produced during thermal decomposition of M(CO)6 in zeolites. The temperature at which molybdenum hexacarbonyls begin to decompose is the lowest: Mo3" is intermediate of stability thermal order the However, W>Mo>Cr.
Keywords: metal hexacarbonyl  zeolite  thermal decomposition  infrared spectroscopy  temperature programmed-mass spectra
