Abstract
TMP, L VP and ZrVP as an inorganic material SUppOit for transition metal catalysts are used
in this project. The basic parameters such as: elemental analysis, IR spectrum, hydrogen ion
exchange capacity, pH titration and moisture contents for each exchanger have been studied.
Catalytic applications of ZrVP, L VP and TMP as a support by loading CrJ+ on each, and
Cu'+ and Fe3+ on ZrVP, have been studied in dehydration of cyclohexanol and in the hydration
of cyclohexene. From the GC analyses the suppOited catalysts were found to be efficient in
dehydrating cyclohexanol but not for the hydration of cyclohexene. The major product identified
by retention time coincidence test and peak enhancement teclmique was cyclohexene. In this
work the most efficient being ZrVP and the percentage composition of the product obtained are
48% for ZrVPlFe3+, 35% for ZrVP/Cr'+ and 29% for ZrVP/C112+
