Abstract:
Layered double hydrotalcites pillared by heteropolyoxometates, ZnAl- GeW11Z (Z=Ni2+, Cu2+) and ZnAl-GeW11 have been synthesized by ion exchange. A procedure for intercalating layered double hydroxides is described in this paper, powder X-ray diffraction and IR spectra measurements confirm that for GeW11O39Z (H2O)6- and GeW11O398- intercalation takes place and the gallery heights are of 9.9Å. The new compounds are found to be calalytically efficient for the esterification of acetic acid with n-butanol in liquid-phase.
Key words: Transition element, Heteropolyoxometales, Clays, Esterification activity
