摘要
In this paper. tungstogallic heteropolyaniou trisubstituted with transition metal ferrum GaW9Fe3 was intercalated into ZnAl-NO3 type anion clay by means of ion-exchange for the first time. XRD patterns show that the pillated derivative possesses a gallery height of 0.98nm. IR spectra exhibit that the Keggin structure of intercalated heteropolyanion is remained. The new material was found to be catalytically efficient for the esterification of phthalic anhydride with 2-ethyl hexanol.
