摘要 研究[Cr_3(M_3-O)(M-OOCH)_6(H_2O)_2OOCH)·xH_2O[表示为(Cr_3FF)],在乙炔、水汽系统中的反应行为时发现,当温度高于220℃时,脱了部分配体的(Cr_3FF)碎片具有活化乙炔进行加氢和加水反应的性能。为进一步探讨这些活性组分,综合采用了差热分析(DTA),热重分析(TGA),高温X射线粉末衍射(HXRD)和红外光谱法(IR)对(Cr_3FF)的热解过程进行定性、定量研究。基于此,讨论了活性组分的本质。 During the study of the reaction behavior of the title comlex [shown as (Cr_3 FF)] in asystem of acetylene and steam, it has been observed that when the temperature was over 220℃some active componednts ware formed by losing part of the ligands of (Cr_3 FF), that canactivate the addition reaction of acetylene with water or hydrogen. In order to clearify thesecomponente the thermal decomposition process of (Cr_3 FF)has been carried out quantitativelyand qualitatively by means of differential thermal analysis, thermogravimetric analysis, hightemperature X-ray powder diffraction, and infrared spectra. On the basis of these experimantsthe nature of the active components has been discussed.
