CORRELATION BETWEEN THE REACTIVITY AND THE STRUCTURAL AND THERMAL-PROPERTIES OF SUPPORTED METAL NITRATES

Montmorillonite-supported iron(III) nitrate and copper(II) nitrate rea gents, and other supported metal nitrates prepared in the same way, we re investigated by thermal and X-ray powder diffraction methods. The m etal nitrates are present on the support in the form of crystalline hy drate and not as acetone solvate as supposed earlier. Thermal decompos ition of metal nitrates that are active in model reactions proceeds in a different way from that of the practically inactive nitrates. In th e former case, water release and nitrate decomposition itself are simu ltaneous process. These and other results contributed to determination of suitable reaction conditions for the montmorillonite-supported rea gents.
